Abstract
The pressure on water resources has led to a decrease in water quality,and salinity stress has become a significant challenge for agriculture.In order to investigate the effect of salinity stress on chickpea growth,a study was conducted in a greenhouse at Ferdowsi University of Mashhad in 2020.The study followed a split plot design based on a randomized complete block design with three replications.Salinity was applied to the main plots at two levels(12 and 16dSm-1)of sodium chloride, and control 0.5dSm-1(tab water) was also used. Additionally,70 chickpea genotypes were placed in the subplots.Four weeks after applying stress and before flowering in salinity levels of 12 and 16dSm-1,65 and 28 genotypes,respectively,had a survival rate of 100-76%.In the salinity level of 12dSm-1,with a decrease in the survival rate,the average content of total photosynthetic pigments also decreased,and the highest average was related to the survival range of 100-76%.In salinity levels of 12 and 16dSm-1,with decrease in the survival rate,the soluble carbohydrates also decreased.With increase in salinity from 12 to 16 dSm-1,shoot dry weight decreased by 15%,11%, 36%,and14% in the survival ranges of25-0, 50-26, 75-51,and 100-76%,respectively.With increase in salinity from 12 to16dSm-1,the sodium concentration increased by 3, 10, 30,and 4% in the survival ranges of 25-0, 50-26,75-51,and 100-76%,respectively.In the salinity level of 12dSm-1,genotype MCC1484,and in the salinity level of 16dSm-1,genotypes include MCC1467 and MCC1834 were superior to other genotypes in most of the studied traits,which can be used for further studies.On the other hand,cluster analysis results showed that the third group,with 28 genotypes,had the highest survival rate.
