Öğe Effect of Rhizobacteria on Yield of Hydroponically Grown Tomato Plants(Int Soc Horticultural Science, 2012) Gul, A.; Ozaktan, H.; Yolageldi, L.; Cakir, B.; Sahin, M.; Akat, S.; Kittas, C; Katsoulas, N; Bartzanas, TIn this study, plant growth-promoting rhizobacteria (PGPR), selected for their ability to promote plant growth and for the biological control of crown and root rot caused by Fusarium oxysporum f. sp. radicis-lycopersici (FORL), were tested on tomato production in perlite under greenhouse conditions. Four PGPR isolates (TR 2/1: Pseudomonas fluorescens bv3, TR 18/1: Pseudomonas fluorescens, TR 21/1: Pseudomonas putida, 14/1y: Pseudomonas fluorescens bv5) selected based on the results of in vitro and in vivo tests from a collection of fifty PGPR strains, were compared with non PGPR inoculated control treatment. A resistant and a sensitive to FORL tomato variety were used. Plants were grown under healthy conditions without FORL inoculation. Seeds were sown on 11 January 2010 and transplanting was realised on 26 February 2010. Harvest period lasted six weeks from 24 May to 2 July. Cumulative fruit weight and number were measured weekly. Tomato plants inoculated with rhizobacteria gave significantly higher yield compared to the control treatment in the first 4 weeks of harvesting period.Öğe Effects of plant growth-promoting rhizobacteria on organic lettuce production(Int Soc Horticultural Science, 2017) Malkoclu, M. C.; Tuzel, Y.; Oztekin, G. B.; Ozaktan, H.; Yolageldi, L.; Ozetkin, GB; Tuzel, YThis study was conducted in order to determine the effects of plant growth promoting rhizobacteria (PGPR) on seedling and head production of organically grown iceberg lettuce ('Papiro'). Seeds treated with Bacillus subtilis (strain 66/3), Pseudomonas putida (strain 18/1K), P. fluorescens (strain 112), P. punonensis (strain 56), B. subtilis + P. fluorescens were sown into vermicompost:local peat (1:1.5, v/v) on January 14, 2015. After germination in growth chamber (18/18 degrees C day/night, 80% relative humidity for 3 days), seedlings were drenched with PGPR suspensions, then plants were moved to a PE greenhouse which is specialized for seedling growing. Seedlings were fertilized by liquid composted farmyard manure (30 L ha(-1)) once a day. Germination rate and period of seeds, fresh and dry weight of seedlings and their nutrient composition were determined when they are ready for planting in 35 days. Then seedlings were transferred into a PE greenhouse and grown according to the rules laid down in organic regulations. Heads were harvested in two months and yield and head quality parameters were determined. It was concluded that observable differences were obtained in the seedling stage. Bacillus subtilis treatment increased the seed germination rate and B. subtilis + P. fluorescens was found promising due to the higher seedling biomass. However, the effects of PGPRs on yield, head size and plant biomass was found insignificant.Öğe Effects of plant growth-promoting rhizobacteria on organic tomato seedling production(Int Soc Horticultural Science, 2017) Ozaktan, H.; Malkoclu, M. C.; Tuzel, Y.; Oztekin, G. B.; Yolageldi, L.; Ozetkin, GB; Tuzel, YThe aim of this research was to determine the effects of different plant growth promoting rhizobacteria (PGPR) on organic tomato seedling growth in peat and vermicompost mixture used as growing medium. Organic tomato seeds (Lycopersicon esculentum 'Melis') were treated with bacterial strains named as Pseudomonas punonensis strains 37 and 56, Pseudomonas putida strain 18/1K, Ochrobactrum pseudintermedium strain 80, Pantoea agglomerans strain 83, Bacillus subtilis strain 66/3, Bacillus thuringiensis strain 99, Pseudomonas fluorescens strains 112, S5/4, 30, and TR21/1. Treated and control seeds were sown into local peat+vermicompost (LP+VC) (1.5: 1, v: v) on July 24, 2014. Trays were left in germination room for 3 days at 24/24 degrees C (day/night) and 80% relative humidity. After germination, plants were moved to a PE greenhouse which is specialized for seedling growing. Seedlings were fertilized by liquid composted farmyard manure (30 L ha(-1)) and they were ready for transplanting after a month. Seed germination period and rate, fresh and dry weights and nutrient composition of shoots and roots were determined. Pantoea agglomerans and Pseudomonas punonensis were found as promising on shoot and root growth respectively in organic tomato seedling production.Öğe First report of Oidium neolycopersici on tomatoes in Turkey(Blackwell Publishing, 2008) Yolageldi, L.; Sin, B.; Onogur, E.Öğe Hybridization breeding program for resistance to monilinia (Monilinia laxa) on apricot(International Society for Horticultural Science, 2020) Bilgin, N.A.; Misirli, A.; Evrenosoğlu, Y.; Yolageldi, L.; Erdogan, A.Turkey is the leading country in production and export of apricots in the world, besides, there are fluctuations in yield, depending on years. In this situation, many factors are effective, pests and diseases also play an important role. Monilinia, which is one of the fungal diseases that appeared especially in the years when climatic conditions suitable leads to serious product loss in apricot production areas. Due to the importance of human and environmental health, intensive breeding programs are carried out in order to obtain genotypes resistant to diseases and having favorable fruit characteristics. In this context, a long-term hybridization breeding project is carried out in order to gain resistance 'Hacihaliloglu' cultivar, which is one of the most important export products of our country and world famous, having superior drying properties but sensitive to monilinia. In this circumstance, genotypes obtained from different hybridization combinations between 'Hacihaliloglu' and resistant cultivars were tested artificial inoculation against disease and transferred to the land. The phonological observations, plant and fruit characteristics in the bearing genotypes were examined. As a result of the evaluations, promising genotypes have been determined and studies are going on. © 2020 International Society for Horticultural Science.

Since then, it has become a common disease in commercial greenhouses in the south and south-western part of Turkey. In order to assess the incidence of the disease and obtain isolates of the pathogen for further studies, a survey was conducted in the greenhouses of two major tomato growing provinces, namely Antalya and Mugla in May of 2008. Diseased plant samples were collected from greenhouses where the crown and root rot had been suspected to occur and symptomatic plants were counted. Fifty-three Fusarium oxysporum isolates were obtained from forty-one tomato greenhouses and twenty-eight of them were selected to use in pathogenicity test. For the pathogenicity tests two tomato cultivars 'Newton F-1' and 'Kardelen F-1' commonly found in commercial greenhouses where the disease symptoms existed, were inoculated by root-deep technique with conidial suspension of those isolates. Based upon their pathogenicity reaction eighteen isolates were identified as F. oxysporum f. sp. radicis-lycopersici. The presence of the pathogen was also confirmed by re-isolations from infected tomato plants on selective media for Fusarium spp. As a result, the incidence of the disease was determined as 26.1 and 85.1% in commercial tomato greenhouses from where the pathogen could be isolated and identified, in Antalya and Mugla, respectively.Öğe Rhizobacteria promoted growth and yield of tomato plants and control of Fusarium oxysporum f. sp radicis-lycopersici(Int Soc Horticultural Science, 2017) Gul, A.; Ozaktan, H.; Yolageldi, L.; Cakir, B.; Ozetkin, GB; Tuzel, YFusarium oxysporum f. sp. radicis-lycopersici (FORL) results in severe losses in the greenhouses and open field tomato crops. In this study, rhizobacteria (RB) were tested on tomato plants for the biological control of FORL and for their ability to promote plant growth and yield. Firstly, 50 RB strains were screened for in vitro growth promotion and biocontrol tests. According to the results of in vitro tests, 9 RB isolates (TR2/1: Pseudomonas fluorescens, TR6/1: P. fluorescens, TR18/1: P. fluorescens, TR21/1: P. putida, TR23/1: P. putida, TR39b: P. fluorescens, 70: P. putida, S5/4: P. putida, 14/1y: P. fluorescens) were selected for in vivo tests realized in growth chamber. A sensitive 'Kardelen F-1' tomato cultivar to FORL was used as plant material. RB were applied as seed coating before sowing and substrate drenching after transplanting, and tested with and without FORL inoculation made before transplanting. RB strains gave rise to significant increase in growth of tomato seedlings, TR2/1 and TR18/1 gave higher values in this respect. RB strains suppressed disease symptoms significantly, TR21/1 and 14/1y were most effective strains for control of FORL. TR 21/1 suppressed disease symptoms by 76%. Four RB (TR2/1, TR18/1, TR 21/1 and 14/1y) were selected for greenhouse experiment, and were tested to determine their effect on growth and productivity of tomato plants in greenhouse under healthy conditions without FORL inoculation. RB increased growth of tomato seedlings and cumulative yield. It was concluded that RB have potential for developing biofertilizers and biopesticides needed in organic farming which avoids the use of synthetic chemicals.
