Abstract

In order to investigate the effect of seed priming with growth regulators on yield and yield components of red bean lines this research was conducted as spilt factorial in RCBD design with three replications. The treatment consists of three levels of irrigation (after evaporation of 60-55, 85-80 and 115-110 mm) two lines of Red beans ( KS31169, D81083) and seed priming including salicylic acid and naphthalene acetic acid at four levels (P0: control, distilled water; P1: 0. 5 m mol L-1 NAA; P2: 0. 7 m mol L-1 SA; P3: combination of SA and NAA at rates of 0. 5 and 0. 7 m mol L-1). The results showed that the simple effects and the interactive effects of genotype × seed priming with on all the studied traits were significant except for the harvest index and pod length. Maximum 100-seed weight of (44 g) and biological yield of (14715. 88 kg h-1 ) were achieved in the KS31169 line through the use of (NAA), under irrigation after 80-85 mm evaporation. The seed yield of (3454. 16 kg h-1) were observed through the use of (NAA) and (SA) pretreatments for drought stress treatment. The results of stepwise regression of yield and the related traits 88 % of grain yield changes was explained by biological yield, grain yield, harvest index, number of seeds per pod and seed weight. Generally, it can be concluded that seed pretreatment can help improve and develop the yield under drought stress, directly and indirectly by affecting the morphological and physiological properties of plants.
