Tuz Stresinin Nohut (Cicer arietinum L.) ve Bezelyede (Pisum sativum L.) Tohum Çimlenmesi Üzerine Etkileri

Salinity is one of the most severe environmental factors limiting the productivity of agricultural crops.This study was conducted to determine the effect of salt stress on seed germination in chickpea (Cicer arietinum L.) and pea (Pisum sativum L.).For this purpose, 4 different pea (Utrillo, Serge, Jof and Bolero) and 4 different chickpea (Kanada, İnci, Azkan and Çağatay) cultivars were used.Four different salt concentrations (50, 100, 150 and 200 mM NaCl) were applied to determine and the effects on seed germination (germination percentage, germination speed, mean daily germination, peak value and germination value) were investigated.In the study, there was a significant decrease in germination parameters in both species with increasing salt level.Seed germination of pea cultivars did not occur on 150 (except Jof) and 200 mM salt stress, while chickpea cultivars didn't germinate on 200 mM (except Çağatay) salt stress.In general, it can be said the critical limit for germination in both species to be 100 mM.Jof cultivar have the highest (46%) germination percentage in 100 mM.In chickpea, the maximum germination percentage at 100 mM (63%) and 150 mM (20%) NaCl was determined in Çağatay.Our findings support that there are differences in tolerance to salt stress between different species or varieties of the same species.
