Host Penetration And Infection By The Anastomosis Groups Ofrhizoctonia Solanikühn Isolated From Potatoes, Erkol Demi̇rci̇, M. Timur Döken
Turkish Journal of Agriculture and Forestry
The modes of penetration and infection of the isolates belonging various anastomosis groups (AG-2 type 1, AG-2 type 2, AG-3, AG-4 and Ag-5) of Rhizoctonia solani Kühn isolated from potatoes were investigated on the underground stems of the host. During the process of penetration, infection cushions were observed in all isolates in addition to the formation of labote appressoria by AG-3, AG-5 and direct hypel penetration of AG-4. Numerous fine infection pegs formed from infection cushions grew between or into epidermal cells following the penetration of cuticula. A similar mode of penetration was also occured by the infection peg produced …
Assessment Of Response To Drought Stress Of Chickpea(Cicer Arietinuml.) Lines Under Rainfed Conditions, Cengiz Toker, M. İlhan Çağirgan
Assessment Of Response To Drought Stress Of Chickpea(Cicer Arietinuml.) Lines Under Rainfed Conditions, Cengiz Toker, M. İlhan Çağirgan
Turkish Journal of Agriculture and Forestry
Totally sixty four chickpea lines were grown for assesment of response to drought stress in the stress and non-stress environments under rainfed conditions. The seed yield of the lines when grown under the non-stress condition increased at a rate of 53% over the in stress condition. The line, FLIP 92-154C, was determinated as the best tolerant line to drought stress environment under the field condition. Also, seed yield strongly correlated with biological yield, harvest index, mean productivity, tolerance to drought stress and drought susceptibility index in the stress environment.

An Investigation On Determination Of Characters Regarding To Seed And Straw Yield Usingdifferent Methods In Common Vetch, Sadık Çakmakçi, Aydın Ünay, Esvet Açikgöz
Turkish Journal of Agriculture and Forestry
In this study, 178 common vecth genotypes were tested in Bursa in 1989-1991. The aim of this study was to determine characters that affect seed and straw yield using simple correlation coefficients, path analysis and stepwise analysis. Days to flower, spirng vigour, seeds/plant and pods/node for seed yield; plant height, spring vigour, leaflets/leaf and pods/node for straw yield were significant characteristics in pre-harvest selections. Harvest index, straw yield, spring vigour and 1000-seed weight for seed yield; plant height, spring vigour, seed yield and harvest index for straw yield were found to be significant in postharvest selections.

Development Of The Downy Mildew Pathogen Bremia Lactucae Ontransgenic Lettuce Expressing A Bacterial \Beta-1,3-Glucanase, Yeter Dede
Turkish Journal of Agriculture and Forestry
A \beta-1,3-glucanase gene from Arthrobacter sp. driven by the 35S promoter was singly transformed into two lettuce cultivars, Cobham Gree and Diana, using the binary vector system of Agrobacterium tumefaciens. Tansformation was confirmed by using Southern and Northern analysis, Npt II enzyme assays and segregation of resistance to kanamycin. Transgenic plants were infected with the letuce downy mildew fungus, Bremia lactucae which contains \beta-1,3-gluncan in its cell wall and alternations in the development the fungus could easily be monitored. Transgenic plants inoculated with B. lactucae showed different levels of resistant responses compared to the control and they were examined microscopically.
