Evaluation of The Effect of Salinity on Some Physiological and Phenological Traits in Durum Wheat Cultivars

38664

To evaluate the effect of salinity on some physiological and phenological traits in durum wheat, a factorial experiment was conducted based on randomized complete block design with three replicates. Treatment was salinity with three levels including control, 60 and 120 mM on ten durum wheat cultivars (Boomer, PGS, 71135, 61130, 605, C1351, KND1000, KDM, Haurani and G1252). Time of stem elongation, time to heading and maturity, chlorophyll content and chlorophyll fluorescence of flag leaf were measured. Results showed that the interaction between salinity and cultivars was significant only for heading time. With increasing salinity in both 61130 and PGS cultivars, heading time increased. Boomer had the lowest maturity time, while PGS had the greatest time to maturity. About the time of stem elongation, 605 and 61130 respectively had the minimum and maximum time of stem elongation. The interaction of salinity and cultivars was not significant for chlorophyll content in the flag leaf, but chlorophyll fluorescence (FV / FM) of flag leaf was significant. C1352 and 71135 respectively had the highest and lowest chlorophyll content in flag leaf.
