The Effects of Waterlogging Stress and Recovery Treatment on Some Common Bean Genotypes

Tolerance and recovery ability of green bean genotypes to waterlogging stress were investigated in terms of morphological and physiological in 15 genotypes. plants were grown under controlled green house conditions at 30/17ºc temperature (day/night) and 50 % relative humidity. when the plants have developed 3-4 true leaves seedlings were exposed to waterlogging stress for 7 days and then taken to normal growth conditions. at the end of waterlogging treatment both roots and leaves fresh and dry weight, total chlorophyll content values were significantly reduced. it was determined that recovery treatment, compared to waterlogging treatment, increased leaf fresh-dry weight, total chlorophyll content. besides, root fresh and dry weight and old leaves’ leaf area varied depending on genotype. after waterlogging treatment the degree of ion leakage (%) was increased at all genotypes more than the recovery treatment. şeker fasulye was determined as the tolerant genotype, whereas y1 was determined as relatively more sensitive genotype. according to the general evaluation, tolerance to waterlogging stress and recovery capacity of green bean genotypes changed depending on root and leaf part.
