Abstract
Screening of tomato genotypes under different concentration of salt-stresses was carried out to find out the salt tolerant tomato germplasm on different Morpho-physiological attributes during October 2011 to February 2012 at the hydroponics laboratory of the Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI). Seven tomato genotypes viz., C-71, C11 x C51, C-51, WP7, WP8, WP2 and BARI Hybrid Tomato-4 and four salinity levels viz.,(control, 4, 6, 10 dS/m) were imposed at pre-flowering stage of tomato genotypes were grown in nutrient solutions. Twenty day old seedlings were transplanted in nutrient solutions. Table salt was added in the nutrient solution to develop salinity of 4, 6 and 10 dS/m. Leaf photosynthesis rate and chlorophyll fluorescence measures were used to evaluate genotypes against salinity. Photosynthetic data reflected Genotype C-71 was fairly tolerant to salinity levels up to 10 dS/m-1 while Genotype WP-7 was found sensitive to salinity. Chlorophyll fluorescence intensity of dark adopted leaves of genotypes might be due to high potential in Ribulose carboxylase (RuBP) of Photo System II.
