Determination of Salt Tolerance Levels of Common Bean (Phaseolus Vulgaris L.) Genotypes Grown in Van Lake Basin

Abstract

In this study, the reactions of some bean genotypes collected from Lake Van Basin to different salt concentrations were examined. For this, 20 bean genotypes were subjected to salt stress (NaCl), 25 mM and 50 mM concentration. For determination of salt resistance in bean genotypes 0-5 scale, the percentage of salt tolerance, shoot-root fresh and dry weight, contents and rate of nutrients (K, Ca, Na, K/Na, and Ca/Na) in shoots. At the end of study, it was determined that common bean genotypes had a high variation in point of response to salt stress. In this variation, G30, G67 and G75 were assigned as tolerance to salt stress, G2, G71, G78 and G94 genotypes were susceptible. © 2016, Centenary University. All rights reserved.
