The effect of salinity on growth and chlorophyll content of six soybean genotypes was investigated. Plants were grown in nutrient solution in a greenhouse experiment to determine the effect of salinity on growth and Chl. a and b content of soybean leaves. Salinity was induced by natural drainage water of salted field to the nutrient solution. Electrical conductivities of the nutrient solution were 2,4,6,8,and l0 ds/m. Salinity induced marked decrease in plant growth and chlorophyll content of soybean genotypes. Increasing salinity level to l0 ds/m decreased plant height, shoot and root dry weight, and Chlorophyll a and Chlorophyll b contents. Soybean genotypes responded differently to increasing salt concentrations. There was a consistent in the percentages reduction of shoot dry weight and Chorophyll a and Chlorophyll b contents. It seems that Lee, Coniquitt and Clark 36k are more tolerant than other genotypes. Chlorophyll a and b content of soybean leaves with or without shoot dry weight can be use as a parameter in screening for salt tolerant in soybeans. |
