DETERMINATION OF SALT TOLERANCE FOR SOME CUCUMBER (CUCUMIS SATIVUS L.) GENOTYPES IN SEEDLING STAGE

Abiotic stress factors has been very important in recent years due to globalwarming. Salinity, which is one of abiyotic stress factors, result in decrease of yieldand quality. Effect of salinity shows difference in plant growth period, plant species and plant varieties. Therefore, it is important that the reaction of salinity isdetermined in seedling stage.This research was carried out in the climatic greenhouse of Batı AkdenizAgricultural Research Institute, Antalya, in 2007. Total 11 genotypes ,8 genotypesconsisting of wild and domestical types, 2 tolerant (Chang chun mici and Nerosimy40) and 1 susceptible(Jinchun) lines were used in the experiment. The dose of 200mM= 20,50 dS/m NaCl was applied to cucumber seedlings to determine reaction ofgenotypes.According to observed symphtoms of the cucumber seedlings, PI 308915 343and PI 308916 343 genotypes from Russia were determined tolerant genotype butPI 179676 (Kakri) genotype from India were susceptible genotype determined inseedling stage.
