Effect of salinity on chlorophyll concentration, leaf area, yield and yield components of rice genotypes grown under saline environment|
Y. Ali, Z. Aslam, M. Y. Ashraf and G. R. Tahir
Salt tolerance in eighteen advanced rice genotypes was studied under an artificially salinized (EC=8.5 dSm-1) soil conditions after 90 days of transplanting. The results showed that the yield per plant, chlorophyll concentrations, fertility percentage, and number of productive tillers, panicle length and number of primary braches per panicle of all the genotypes were reduced by salinity. However, genotypes viz. Jhona-349 x Basmati- 370, NR-1, DM-59418, DM-63275, DM-64198 and DM-38-88 showed better salinity tolerance than others.
