Öğe Assessment of the quality losses of fresh fig fruits during transportation [Taze İncir Meyvesinin Taşi{dotless}nmasi{dotless} Sirasinda Oluşan Kalite Kaybinin Deg`erlendirilmesi](2010) Çakmak B.; Alayunt F.N.; AkdenïZ R.C.; Aksoy U.; Can H.Z.Turkey is one of the main fig fruits producers in the World. The protection of the fig fruit quality in the chains from harvesting to marketing is very important. Vibration often causes some damages to perishable fruits in transportation and reduces their quality. The fruit injury due to vibration is related to the transportation characteristics of vehicles, packaging boxes and the conditions of the roads. The objective of this study was to investigate the effectiveness of packaging box by different materials to decrease the damages of vertical vibration on the quality of three fresh fig varieties (Yediveren, Sarilop and Bursa Black) during transportation. The experiments were carried out in two stages. In the first stage; the frequency and acceleration values of truck were determined during the real transportation. In the second stage, these values were applied on the simulator (shaker) to examine the effect of vibration on fresh figs packaged with three different boxes. The results showed that the cardboard packaging box was not proper for transporting of the fresh fig fruits in all road conditions. The mass loss of fresh fig fruits packed with cardboard box were found to be 2.5 times more than extruded and expanded polystyrene boxes at 16 Hz frequency and 2.54 m s-2 acceleration. Sarilop fig variety was more damaged under the off-road. For long highway road conditions, Bursa Black fig variety was found the most affected fig variety. © Ankara Üniversitesi Ziraat Fakültesi.Öğe Estimation of leaf area index in some breba fig cultivars(International Society for Horticultural Science, 2008) Can H.Z.Determination of leaf area index which is a key factor in many physiological processes in plants plays a crucial role. Despite the difficulty of measurement, without a suitable instrument it is quite time consuming and destructive. The exact measurement of leaf area index requires the measurement of the total leaf area of the canopy. For this reason, this study aims at developing a measurement procedure to estimate the leaf area index in some breba fig cultivars. During the experiment a digital plant canopy analyzer was used to control measurements. Breba fig trees of 'Susak', 'Dumanli Kara', 'Horasan', 'Beyaz Orak', 'Siyah Orak', 'Yediveren', 'Siyah Cicek', 'Beyaz Cicek', 'Noire de Coromb' (France), 'Banana Fig' (France) and 'Nazareth' (Israel) were selected as the plant material. The nearest measured LAI values to estimated LAI values were obtained from the Northern west direction of the canopy in Nazareth. On the other hand, from the Southern east and Southern west directions in other evaluated breba crop fig cultivars.Öğe Impact of yearly conditions on major physical and chemical properties of fresh, semi-dried and sun-dried fig (Ficus carica L. 'Sarilop') fruit(International Society for Horticultural Science, 2017) Şen F.; Aksoy U.; Özer K.B.; Can H.Z.; Köseoglu I.; Konak R.The study was carried out on fresh, semi-dried (shriveled) and fully sun-dried fig (Ficus carica L. 'Sarilop') fruit from the same orchard during four consequent crop years in order to assess the effect of yearly conditions on physical and compositional properties. The samples were collected at fresh, semi-dried and dried fig stages. The mean moisture content and water activity levels were similar in all four years . The total soluble solids contents were the highest in 2012. The effect on titratable acidity and fruit firmness were limited. The colour values L*and b*remained almost constant however a*value of fresh fruit attained a higher value in 2012. The fruit samples contained mainly fructose and glucose however low concentrations of sucrose were determined in some dried fruit samples. The major impact of yearly conditions was found on the ratio of defected fruit (sunscald, crack and brown-neck). Yearly differences were significant also in terms of fruit weight, total soluble solids, and sugar composition of fig fruit.Öğe Response of satsuma mandarin (Citrus unshiu Marc.) trees budded on trifoliate orange (P. trifoliata) to salinity due to seawater intrusion(International Society for Horticultural Science, 2002) Can H.Z.; Aksoy U.; Anaç S.; Kukul Y.S.; Okur B.The research aimed at assessing the level of sea water intrusion as well as its impact on productivity of Satsuma trees. Salinity parameters of irrigation water and soil, physiological parameters as photosynthesis and transpiration rates, relative water content, and stomatal density and fruit yield were determined. Most of the sampling was carried out prior to and during the period of irrigation in summer and during harvest. Among the analysed parameters, transpiration (E), photosynthesis (A) and water use efficiency (WUE=A/E), leaf area, stomatal density and relative water content (RWC), were found to be highly correlated and representing the case. The yield was reduced drastically towards the sea line with increasing salinity. All the determined salinity parameters proved to exert cumulative adverse effect on yield and tree vigour. The unit gas exchange capacity of the leaf was reduced parallel to the decreases in leaf area and stomatal density.
