Abstract

Effect of salinity stress, with four levels 1.7, 4.7, 8.7, and 14.5 dSm-1, on growth and yield of Zagros and Tajan wheat cultivars were evaluated. A factorial experiment was conducted using a randomized complete block design with three replicates. Vegetative and reproductive variables were measured at anthesis and maturity. Leaf area and dry weight and total plant dry weight at anthesis decreased at 8.7 dSm-1 salinity, but the decrease was not significant for Tajan. Salinity treatments of 8.7 and 14.5 dSm-1 caused significant decrease in stem number, stem and leaf dry weight, spike number and weight and total dry weight, but differences between salinities of 1.7 and 4.7 dSm-1 were not significantly different. Seed dry weights of both cultivars were significantly decreased only by salinity of 14".5 dSm-1. Seed number per spikelet of Tajan increased by increasing salinity, but in Zagros the greatest seed number per spike let was observed at 4.7 dSm-1. Salinity, had no effect on harvest index of both cultivars, but increased in Tagen and decreased in Zagros. Salinity of 8.7 and 14.5 dSm-1 significantly decreased Zagros grain yield in comparison to salinity of 1.7 dSm-1. However, Zagros over-yielded 46% compared to Tagen in salinities of 4.7, 8.7 and 14.5 dSm-1
