Abstract

In order to evaluate DROUGHT stress effects induced by polyethylene glycol on seedling characteristics and growth of 8 BREAD WHEAT genotypes (Sardari 101, Homa, Rasad, Azar 2, Zarrin, Gascogen, Marten and Sayson), a 4×8 factorial experiment was carried out using completely randomized design with three replications. Results showed significant differences between BREAD WHEAT genotypes in all studied characteristics, except in radicle length (RL) plumule length (PL) ratio, root fresh weight (RFW), and root fresh weight (RFW) to plumule fresh weight (PFW) ratio. Interaction effects of genotype × DROUGHT stress levels were significantly different in all seedling traits except radicle length (RL), seedling fresh weight (SFW) and plumule fresh weight (PFW). With decrease of water potential, germination percentage, RL, PL, coleoptile length (CL), SFW, and PFW were decreased. According to CLUSTER ANALYSIS, the 8 genotypes were placed in 3 different groups. Orthogonal polynomial analysis showed that dryland and irrigated cultivars were in two different groups. Under DROUGHT stress condition, Homa had the highest RL and PL as well as higher proportion of SFW and plumule fresh weight compared to the other cultivars. Homa showed more tolerance to DROUGHT stress than the other studied cultivars.
