Öğe Alterations in quality characteristics and bioactive compounds of blackberry fruits subjected to postharvest salicylic acid treatment during cold storage(Wiley, 2024) Sakaldas, Mustafa; Sen, Fatih; Gundogdu, Muttalip; Aglar, ErdalBlackberry deteriorates rapidly after harvest due to its sensitive structure, limiting their storage time to about a week and resulting in significant economic losses. The study was conducted to determine the effects of salicylic acid applications on postharvest fruit quality in blackberries, the harvested fruit was immersed in salicylic acid solutions prepared at concentrations of 0.5, 1, and 1.5 mM for 15 min. Measurements and analyses such as weight loss, decay rate, soluble solids contents (SSC), pH, acidity, respiration rate, vitamin C, organic acids, and phenolic compounds were performed on fruits stored for 12 days with intervals of 4 days. Applying salicylic acid to fruits resulted in significantly less weight loss and decay rate. Salicylic acid application was effective in increasing SSC rate and decreasing titratable acidity with increasing storage time, and lower SSC and higher titratable acidity were measured with this application. Salicylic acid maintained organic acids and vitamin C postharvest. The decreases in individual phenolic compound levels occurred with extended storage time. Salicylic acid application generally was effective in maintaining concentrations of phenolic compounds during storage, and it was found to be effective on fruit quality, with effectiveness varying depending on application dosage. The study identified 1.5 mM as the most effective dosage of salicylic acid, which could be utilized to maintain postharvest quality and extend cold storage in blackberries. A study was conducted to assess the effects of salicylic acid on postharvest blackberry quality. Measurements such as weight loss, decay rate, soluble solids contents, pH, titratable acidity, respiration rate, vitamin C, organic acids, and phenolic compounds were taken over 12 days at 4-day intervals. Salicylic acid-treated fruits showed significantly less weight loss and decay. It also helped maintain organic acids, vitamin C, and phenolic compounds.imageÖğe Can using a peel-away sheath in shunt implantation prevent ventricular catheter obstruction?(Springer, 2011) Camlar, Mahmut; Ersahin, Yusuf; Ozer, Fusun Demircivi; Sen, Fatih; Orman, MehmetShunt obstruction is the most common shunt complication. In 2003, Kehler et al. used peel-away sheath while implanting the ventricular catheter in 20 patients. They found less revision rate in the peel-away sheath group. We aimed to test the efficacy of this technique in cadavers. We used 100 fresh brains obtained from medicolegal autopsies. Posterior parietal and frontal approaches were used to puncture the lateral ventricle in each cerebral hemisphere. The ventricle is punctured with a peel-away sheath system. After the ventricle is reached, the mandarin is retracted and the ventricular catheter is introduced through the opening. The ventricular catheter was removed from the ventricle, the opening at the tip of the ventricular catheter was checked out for obstruction, and the number of patent and plugged openings was recorded. This procedure was repeated four times for each location with and without using peel-away sheath. The control group consisted of the procedures done without using peel-away sheath. The number of the plugged openings in the peel-away sheath group was significantly smaller than the control group. There was no significant difference between the two groups in terms of gender and left and right cerebral hemispheres. The obstruction rate was significantly lower in the posterior parietal approach. Pearson's correlation showed that increasing age was associated with less obstruction rate. Peel-away sheath decreases the number of plugged openings of the ventricular catheter. A clinical cooperative study is needed to prove that a peel-away sheath should be included in the ventricular shunt systems in the market.Öğe DETERMINING EFFECT OF PHOSPHINE (ECO2FUME (R)) FUMIGATION UNDER ATMOSPHERIC AND VACUUM CONDITIONS ON DRIED FIG QUALITY(Parlar Scientific Publications (P S P), 2015) Sen, Fatih; Aksoy, Uygun; Emekci, Mevlut; Ferizli, Ahmet GurayDried fruit are foods with a long shelf life although several factors, including storage pests,. may limit their marketability. Prior to the decision to phase it out under the Montreal Protocol, Methyl Bromide (MB) was the most extensively used fumigant to control storage pests, due to its efficacy and relatively low cost. The objective of the study was to test the effectiveness of two phosphine (PH3) concentrations (1000 and 1500ppm) under conditions of normal atmospheric pressure (760mmHg) and vacuum (50 and 100mmHg), in order to develop suitable alternatives to MB. For inclusion in the dried fig industry, MB alternatives should, of necessity, be able to prevent storage pest problems via brief exposure periods, as well as preserve the fruit quality. In the experiment, the major quality parameters were analyzed after two months of storage under ambient conditions and compared with the untreated (0% PH3/760mmHg) control. The results revealed that the phosphine treatments revealed no negative effects on the sugaring index, total soluble solids, titratable acidity, total phenolic content and antioxidant activity of the dried figs; however, they exerted a limited effect on the water content, water activity and firmness of the treated fruit. Both the phosphine treatments, under vacuum at 50 mmHg, and 1500ppm PH3 at 100mmHg resulted in lower L* and C* values causing darker fruit color. Therefore, ECOFUME (R) treatment for 24 hours is recommended due to its low investment, operational costs and short exposure period.Öğe DEVELOPMENT OF FRESH MARKET TOMATO LINES WITH SUPERIOR QUALITY ATTRIBUTES(Parlar Scientific Publications (P S P), 2020) Simsek, Duran; Duzyaman, Eftal; Sen, FatihAs a common practice in vegetables, breeding programs designed to develop F1 hybrids mostly focused on yield and disease and pest resistance in tomatoes. However, breeding programs are prioritizing fruit quality attributes to satisfy consumers in. To stay competitive in ever changing markets, seed companies take fruit quality criteria into consideration as yield increase leveling off for hybrid tomato. Therefore, the study was designed to develop new tomato lines with superior fruit quality. Advanced tomato lines resistant to tomato yellow leaf curl virus (TYLCV), tomato spotted wilt virus (TSWV), root-knot nematods (Mi), Verticilium dahlie (Va), Fusarium oxysporum (F. radici Frl. and F. lycoperci I-1, I-2, I-3) and powdery mildew (o1-1, o1-2) were used as the plant materials. the 102 tomato genotypes suitable for autumn-spring cultivation were assessed for fruit quality parameters replicated in time and space in greenhouse trials. the 33 of advanced tomato lines exhibited relatively superior quality attributes for one or more traits measured. Based on parental line results, compatible lines for fruit quality were crossed, resulting with 12 hybrids with commercial level competitive advantage. Four of the 12 hybrids that combined fruit quality with yield and disease resistance were especially found to be highly cornpletive in fresh market tomato market.Öğe The effect of different concentrations of pre-harvest gibberellic acid on the quality and durability of 'Obilnaja' and 'Black Star' plum varieties(Soc Brasileira Ciencia Tecnologia Alimentos, 2016) Harman, Yunus; Sen, FatihThe research work aimed at investigating the effect of pre-harvest gibberellic acid (GA3) treatment on the quality of 'Obilnaja' and 'Black Star' Japanese plum varieties. GA3 was sprayed onto the trees during the fruit color break at 0, 25, 50, 75, and 100 ppm concentrations. After pre-cooling, the plums were placed in modified atmosphere packages and exposed to the following conditions as follows: short storage-transportation (ST) [20 days at 2 degrees C and 90% relative humidity (RH)]; distribution center (DC) (5 days at 6 degrees C and 80% RH), and shelf life conditions (SL) (2 days at 20 degrees C and 70% RH). Pre-harvest GA3 treatments increased the fruit weight and size. Treatment of GA3 at 50, 75, and 100 ppm increased the fruit flesh firmness and total soluble substances (TSS) values in both the plum varieties during storage, transport, and marketing; it also limited the weight loss during the marketing process. Treatment of GA3 had no significant effects on the color, titratable acidity (TA), and the total phenolic and antioxidant activity values of plums. Pre-harvest GA3 treatment at 50 ppm GA3 can be thus recommended for both the plum varieties due to its effect on the fruit quality.Öğe Effect of different covering materials used during the pre-harvest stage on the quality and storage life of 'Sultana Seedless' grapes(Soc Brasileira Ciencia Tecnologia Alimentos, 2014) Sen, Fatih; Kesgin, MetinCovering the grapevine rows to delay the maturity and harvest date became widely practiced in 'Sultana Seedless' vineyards. The research work was conducted to test different cover materials (polypropylene cross-stitch, life pack, mogul and transparent polyethylene) in respect to their effects on grape quality and storability. Harvest was delayed for one month in covered plots. Harvested grapes were packed and transferred to storage rooms after pre-cooling. During packing, the grape clusters were sealed in PE bags with sulphur dioxide pads. The grapes were stored for 90 days in the first year and 120 days in the second year, at -0.5 degrees C and 90% RH. All the grape clusters were healthy and of marketable quality after 90 days of storage period. In the first year, at the end of the storage, only those grapes harvested from the rows covered with polypropylene cross-stitch showed fungal growth. The sensory quality scores revealed a lower level of preference after 120 days of storage. The effects of the covering materials tested were similar regarding grape quality and storage performance except the transparent polyethylene that damaged the grapevine leaves.Öğe The effect of different LED wavelengths used in the cultivation of Pleurotus ostreatus on quality parameters of the mushroom during the storage process(Elsevier, 2024) Cetin, Mehmet; Atila, Funda; Sen, Fatih; Yemen, SevvalThis study aimed to investigate the effects of light emitting diodes (LEDs) of different wavelengths (white, red, blue and green) used in Pleurotus ostreatus cultivation on post-harvest mushroom quality, storage process and maintenance of mushroom quality characteristics during storage. The mushroom was exposed to different LED wavelengths for 8 and 12 h per day during fructification period. The effects of these treatments were observed during post-harvest and storage periods, focusing on changes in color, weight loss, antioxidant capacity (FRAP), and total phenolic content (TPC). The harvested mushrooms were stored at 1 degrees C for 12 days, and samples were taken every 4 days to analyze mentioned parameters. After harvest, L*,a*,b* values of the fruiting bodies grown under different LEDs ranged 56.5 - 69.8, 2.0 - 3.84, 12.2 - 15.9 respectively, whereas TPC and FRAP values varied from 54.4 to 78.5 mg GAE/100 g fw and 6.14 to 7.59 mu mol TE/g fw, respectively. The values of L*, a*, b*, browning index (BI), and yellowness index (YI) demonstrated a clear postponement of discoloration in the samples exposed to 8 h of red LED and 12 h of green LED compared to the control group at the end of the storage period. The TPC of the fruitbody cultivated under red LED (8 h per day) was markedly increased after 12 days (54.4 to 95.1 mg GAEs/100 g fw), but LEDs did not affect the maintenance of antioxidant capacity in P. ostreatus. The results showed that red LED applied for 8 h per day during the fructification period enhanced TPC with minimal effects on the color during cold storage.Öğe Effect of different phosphine gas concentrations against Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae) on tomato and green pepper fruit, and determination of fruit quality after application under low-temperature storage conditions(Entomological Soc Turkey, Ege Univ, 2018) Erturk, Sait; Sen, Fatih; Alkan, Mustafa; Olculu, MuratIn this study, we investigated the control of western flower thrips [Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae)], which is an important pest in tomato and green pepper growing areas in Turkey, under cold storage conditions with phosphine fumigation. The trials were conducted in Mersin in 2015, due to infestations of F. occidentalis damaging the export quality of tomatoes and green peppers. The experiments were conducted by using ECO2FUME (R) with different phosphine gas concentrations including 500, 1000 and 2000 ppm. Fumigation chambers were kept at 4 degrees C. Lowest mortality was seen at 500 ppm gas concentration with 72% for larval stage on tomatoes and 73.75% mortality for pupal stage on green pepper. The data demonstrate that the minimum requirement of phosphine gas concentration 100% mortality of all stages of F. occidentalis was at 2000 ppm. The quality of treated fruit was investigated by analyzing weight loss, sensory quality, fruit firmness, fruit skin color, total soluble solids, titratable acidity contents, physiological and pathological disorders. After treatment, there were no changes in physiologic, pathological and shelf-life properties of the products. The results indicated that, phosphine is a suitable fumigant at low temperature for disinfestion of F. occidentalis from tomatoes and green peppers before shipment.Öğe The effect of preharvest gibberellic acid applications on fruit quality of 'Angelino' plums during storage(Elsevier Science Bv, 2016) Erogul, Deniz; Sen, FatihHigh-performance preharvest treatments can ensure maintenance of quality during storage. In this study, gibberellic acid (GA(3)) was applied on the trees in the preharvest stage to study its effects on the storage potential of the 'Angelino' plums. The treatment was applied at 50 and 75 mg/L concentrations, on the 8th, 10th, 12th and 14th 'week after anthesis' (WAA). The results of the GA(3) applications on the 'Angelino' plum quality after 90 days of storage and an additional 2 days of shelf life showed a decrease in weight loss, with a corresponding increase in fruit flesh firmness, total soluble solids and titratable acidity with the treatment. The fruit skin hue values were higher in the GA(3) treated plums, whereas no change was observed in the total antioxidant activity and total phenol contents. Overall, the effect of the preharvest GA3 application on the 'Angelino' plum quality during storage at 0 +/- 0.5 degrees C and 90-95% relative humidity for 90 days was positive.

In the study, oak sawdust (OS) was used as a base substrate, and cottonseed hulls (CSH) and olive press cake (OPC) were added at the ratios of 9:1, 8:2 and 7:3 to prepare the growing media. The control medium was prepared using OS and wheat bran (WB) at the rate of 8:2. The spawn run-period was shorter in all H. erinaceus isolates growing in the OS:WB (control) medium. The yield and BE (%) of H. erinaceus isolates ranged between 76.7 and 152.9 g/kg and 22.3-44.4%, respectively, depending on the growing medium used. The highest yield and BE% for all H. erinaceus isolates, except He-Trabzon, was obtained on 70S:3CSH medium. The nutritional composition of H. erinaceus isolates varied with the growing medium, but there was no direct relationship between the macro- and micro-element content of the growing media and the nutrient content of the fruitbodies. The antioxidant activity and phenolic content of H. erinaceus isolates grown on different growing media ranged between 1.76 and 4.92 mu mol TE/g fw and 0.318-0.663 mg GAE/g fw, respectively. The antioxidant activity and phenolic content of He- Ankara, He-Denizli and He-Trabzon were not affected by the growing media, whereas the addition of OPC to the oak sawdust substrate had a noticeable effect on the phenolic content and antioxidant activity of the fruitbodies of HE-Izmit. According to the results, cotton seed hulls and olive pess cake can be recommended as alternative additive materials to wheat bran to increase the yield of H. erinaceus. Finally, the use of olive press cake as substrate incrases the phenolic content of H. erinaceus mushrooms.Öğe The effectiveness of growth cycles on improving fruit quality for grafted watermelon combinations(Soc Brasileira Ciencia Tecnologia Alimentos, 2018) Alan, Ozlem; Sen, Fatih; Duzyaman, EftalTwo growth cycles per year, i.e., for early growing season (EGS) and late growing season (LGS) production, both of which are widely preferred in temperate climates, have been investigated for their effects on fruit quality attributes such as appearance; firmness; the content of total soluble solids, sugars, and total phenol; and antioxidant activity. Two watermelon [Citrullus lanatus (Thunb.) Matsum and Nakai] cultivars (cv. 'Anthem F-1' and cv. 'Crimstar F-1') were used as scion. Two C. maxima x C. moschata hybrids (cv. 'Shintoza F90' cv. 'Obez') and one Lagenaria siceraria rootstock cv. 'Macis' were used as rootstock. Self-rooted and self-grafted plants were used as controls. EGS resulted in a reduction of fruit shape index, rind thickness, juice pH, hue values, and glucose content as compared to LGS for both the cultivars. On the other hand, total soluble solids of cv. 'Crimstar', fructose of cv. 'Anthem', and the antioxidant activity of cv. 'Anthem' increased. The total phenol content was unaffected by the scion/rootstock combinations or growth seasons for both the cultivars. Most of the fruit quality attributes increased when a specific rootstock/scion combination and growth season was used and these combinations may change in relation to cultivar. It is important to evaluate and select suitable scion/rootstocks for each growth condition created by ecology and growth cycle to guarantee high fruit quality.Öğe Effects of 1-methylcyclopropene, methyl jasmonate and salicylic acid on physicochemical properties and wooliness of nectarine fruit during cold storage(BMC, 2024) Sen, Fatih; Yilmaz, Enes; Ozturk, BurhanBackgroundOwing to its high perishability, the market life of nectarine fruit is very short. Cold storage is a principal approach to limit post-harvest quality loss in nectarines. The objective of this research was to evaluate the impact of postharvest methyl jasmonate (MeJA), salicylic acid (SA) and 1-methylcyclopropene (1-MCP) on quality properties of nectarine fruit, specifically weight loss, firmness, phenolics and antioxidant activity, following cold storage and subsequent shelf life. Fruit immersed in water were considered as control. The fruit were stored at 0 +/- 0.5 degrees C and 90 +/- 5% RH for 56 d, then kept at 20 +/- 0.5 degrees C and 70 +/- 5% RH for 2 d in shelf life.ResultsThe results demonstrated that single or combined treatments of MeJA, SA and 1-MCP were effective on quality characteristics. During cold storage, fruit treated with MeJA + 1-MCP (3.66%) and SA + 1-MCP (3.54%) exhibited lower weight loss than the control (4.08%). In the final two measurements of storage, the flesh firmness of fruit treated with SA + 1-MCP (54.5 and 54.06 N, respectively) was higher than that of the control. At the end of cold storage, the SA + 1-MCP treatment (17.4%) exhibited higher soluble solids than the control (15.37%) and SA (15.20%) treatments. However, the total phenolics content was found to be higher in nectarine fruit treated with single SA than in the control, as well as in fruit treated with SA + 1-MCP and single 1-MCP. Wooliness in fruit treated with 1-MCP, SA and MeJA was found to be lower than in the control, while fruit had higher acceptance.ConclusionsAs a result, the SA + 1-MCP and MeJA + 1-MCP treatments were more efficacious in retarding the weight and firmness decline of nectarine fruit during storage. Also, it was revealed that 1-MCP, SA and MeJA could be employed as efficacious instruments in nectarine fruit with respect to wooliness and acceptance, which influence consumer preferences.Öğe Effects of aminoethoxyvinylglycine treatment by vacuum infiltration method on postharvest storage and shelf life of tomato fruit(Elsevier Science Bv, 2017) Candir, Elif; Candir, Altan; Sen, FatihThe aim of this study was to determine effects of postharvest aminoethoxyvinylglycine (AVG) treatment using vacuum infiltration method on retardation of ripening, storage and shelf life of tomato fruit. In the Experiment-1, beefsteak 'Grando F1' tomato fruit was harvested at breaker stage and treated with AVG at six different doses (0, 62.5,125, 250, 500 and 1000 mg L-1) and three different vacuum pressures (0 kPa, -20 kPa and -30 kPa) using vacuum infiltration method and kept at 20 degrees C for 8 d. The AVG treatment of 1000 mg L-1 at -30 kPa reduced ethylene production rate by 45.53%, delayed color changes and extended the number of days reaching to red ripe stage from 6 to 8 d at 20 degrees C and was confirmed as the optimal treatment for the maximum retardation of tomato fruit ripening by response surface methodology. In Experiment-2, untreated and treated breaker 'Grand F1' tomato fruit with 1000 mg L-1 at -30 kPa were kept at 12 degrees C for 0, 5, 10, 15 or 20 d and for 2 d at 20 degrees C after cold storage. AVG treated fruit had lower ethylene production rate, lycopene content, a* and C* values and higher fruit firmness, chlorophyll content, L* and h degrees values, compared to control during storage and shelf life period. For shipping to distant markets, storage and shelf life of untreated fruit were 10 d at 12 degrees C plus 2 d at 20 degrees C while AVG treatment extended storage and shelf life to 20 d at 12 degrees C plus 2 d at 20 degrees C.

The present study investigated the effects of gibberellic acid (GA(3)) treatment at different concentrations and during different cultivation periods after full bloom on the next year's fruit thinning and the current year's fruit quality. GA(3) was applied to plum trees at concentrations of 50 and 75 mg/L at 12 and 14 weeks after anthesis (WAA). GA(3) treatment at a concentration of 75 mg/L 14 WAA decreased harvest yield by 27.93%, whereas yields were similar to that of the control treatment under the remaining experimental conditions. The main impact was on fruit size: trees treated with GA(3) 14 WAA had significantly larger fruit than did trees under the other treatments. In consideration of the reduction to total yield, 50 mg/L is recommended for thinning purposes in Japanese plum. Fruit color, total soluble content concentration, and fruit firmness were increased after GA(3) application. The antioxidant activity of the untreated trees was higher than that of the GA(3) treated trees, whereas phenol content was determined to be similar.

'Angeleno') During Cold Storage(Springer, 2023) Uysal, Gulsah; Erogul, Deniz; Dayioglu, Ali; Sen, Fatih; Oguz, IlbilgeThe aim of this study was to determine the effects of 1-methylcyclopropene (1-MCP) and modified atmosphere (MAP) packaging on quality properties of plum (Prunus salicina Lindl. cv. 'Angeleno') during cold storage. The study comprised of six different applications as: (a) Control (b) 1-MCP, (c) MAP1, (d) MAP2, (e) 1-MCP + MAP1 and (f) 1-MCP + MAP2. 1-MCP was applied at the dose of 625 ppb at 2 +/- 0.5 degrees C for 24 h. The plum fruit were then stored at 90% relative humidity at 0 +/- 0.5 degrees C for 60 days. Samples were taken at 20-day intervals and kept an additional 2 days under shelf-life conditions to carry out measurements and analyses. In MAP treatments, the weight loss was significantly reduced during cold storage of plum fruits. Changes in fruit flesh firmness, color and overall appearance during storage were more limited in plums packed in MAP and receiving 1-MCP treatment. The respiration rate, ethylene production and decay rate were lower in MAP packages or 1-MCP treatments than in control fruits. The results show that 'Angeleno' plum fruit can be stored successfully for 120 + 2 days when packed in MAP after 1-MCP treatment.Öğe Effects of the post-harvest application of methyl bromide alternatives on storage pests and quality of dried fig(Tubitak Scientific & Technical Research Council Turkey, 2009) Sen, Fatih; Meyvaci, Kamer Betuel; Aksoy, Uygun; Emekci, Mevluet; Ferizli, Ahmet GuerayStorage insect pests, microbial deterioration, and mycotoxins are major threats to dried fruit. Methyl bromide (MeBr) was the fumigant used to control Pests until it was banned. The present study compared the use of MeBr (60 g m(-3) for 24 h) and alternatives-magnesium phosphide (1 and 2 g of phosphine (Ph(3)) per ton of dried fig for 5 days), and carbon dioxide (CO(2)) at atmospheric pressure (in gas tight cubes for 5 days) and high pressure (2 h in pressurized tanks at 25 bars)-in controlling major pests (Ephestia cautella (Zell.) and Carpoglyphus lactis) of dried fig and in respect to dried fig quality. Fruit quality was investigated before exposure and after 2 months of storage at ambient conditions by analyzing moisture content, water activity, Surface color, firmness, total soluble solids, titratable acidity, PH, and sugaring index. The effect on fruit Surface was examined under a scanning electron microscope. The results show that the tested methods effectively controlled storage pests Without any major adverse effects on quality, and each had an advantage for the implementation stage. Magnesium phosphide treatment of 1 g t(-1) for 5 days is recommended due to its low investment and operational costs, CO, in pressurized tanks is recommended due to its short exposure period, and CO, under atmospheric pressure in gas-tight cubes is recommended due to its low cost and suitability for organic production.Öğe FORENSIC AUTOPSIES PERFORMED ON ELDERLY PEOPLE IN IZMIR: 2004-2007(Gunes Kitabevi Ltd Sti, 2012) Kaya, Ahsen; Senol, Ender; Bilgin, Umut Erdar; Kocak, Aytac; Aktas, Ekin Ozgur; Erturk, Suheyla; Sen, FatihIntroduction: We aimed to obtain statistical data and reveal the causes of deaths reliably, and to draw attention to the importance of forensic autopsies by examining the features of the autopsies performed on elderly people aged 65 and over in Izmir. Materials and Method: In this study, 934 cases aged 65 and over whose autopsies were performed at The Council of Forensic Medicine Branch of Izmir, between 2004 and 2007 were analyzed retrospectively. Data were analyzed by SPSS for Windows. Results: 650 of 934 cases were male, 284 of them were female. Average age of the cases was 73.9 +/- 6.7. The leading causes of deaths were cardiovascular diseases (n=331), traffic accidents (n=94), firearm injuries (n=31) and hangings (n=60) in the natural, accidental, homicidal and suicidal groups respectively. Conclusion: Old population is increasing rapidly in our country, as in all of the world. Results of this study showed that both natural and unnatural causes of deaths of the elderly as revealed in autopsies showed similarities with the results of younger autopsies. This study has supported the view that data obtained from forensic autopsies are of importance in order to reveal the causes and origins of deaths in the old age reliably.Öğe HOW GROWING CYCLES AFFECT PLANT GROWTH AND YIELD OF GRAFTED WATERMELON COMBINATIONS(Parlar Scientific Publications (P S P), 2017) Alan, Ozlem; Duzyaman, Eftal; Sen, FatihGrafting is an alternative approach to reduce crop damage resulting from soil-borne pathogens and increase plant abiotic stress tolerance, which in turn increases crop production. There is usually consensus among researchers that grafting watermelons improve most of the vegetative growth and yield characteristics. On the other hand, there are still some differences in the literature as to the effects of grafting on some growth characteristics such as flowering and fruit ripening date. Two growing cycles per year, i.e. for early growing season (EGS) and late growing season (LGS) production, both of which are widely preferred in temperate climates have been investigated for their effects on plant growth and yield parameters such as main stem length, shoot dry weight, root length, number of days male and female flower formation, fruit ripening date and yield attributes. Two watermelon (Citrullus lanatus (Thunb.) Matsum and Nakai) cultivars (cv. 'Anthem F-1' and cv. 'Crimstar F-1') were used as the scion. Two C. maxima x C. moschata hybrids (cv. 'Shintoza F90' cv. 'Obez'), and one Lagenaria siceraria rootstock cv. 'Macis' were used as rootstocks. Self-rooted and self-grafted plants were used as control. EGS resulted in a reduction of main stem length, number of lateral stems, number of leaves, shoot dry weight and root length. On the other hand, number of days first male and female flower formation and number of days first ripe fruit increased comparing to LGS in both cultivars. However, some interactions between the growing season and the used cultivar also seem to exist. EGS reduced root dry weight of cv. 'Crimstar' but increased fruit number and fruit yield per plant of cv. 'Anthem'. Some of the plant growth and yield attributes increased when a specific rootstock-scion combination and growing cycle used. Neither the vigorous hybrids of C. maxima x C. moschata (represented by 'Shintoza' and 'Obez') nor Lagenaria siceraria represented by 'Macis' could be categorized as having constantly superior plant growth and yield traits for at least one of the cultivars in at least one of the field trials. It is important to evaluate and select suitable rootstock scion for each growing condition created by ecology and growing cycle, to guaranty high vegetative growth and yield.
