Abstract: Leaf temperature was 30.45 0C as noticed with 150 ppm SA and the highest per cent decrease was 30.46 0C noticed in RGN-229 under late sowing at siliqua initiation stage. There was increase in membrane stability index with days after sowing in both genotypes under normal as well as late and very late sown it decreased with delay in sowing. Spray of SA could increase the membrane stability in both genotypes under normal, late and very late sown over control but the higher increase membrane stability index was 70.45 per cent noticed with 150ppm SA in both genotypes and the highest percent increase in membrane stability index was 24.64 per cent as noticed in RGN-229 under normal sown at siliqua initiation stage. Chlorophyll stability index increased with different days after sowing under three different dates of sowing in both genotypes. It decrease delay in sowing. Spray of SA could restore the chlorophyll stability in both genotypes under three dates of sowing. Higher increase in chlorophyll stability was 49.70 per cent observed with 150 ppm SA in both genotypes and the percent increase in chlorophyll stability index was 32.25 per cent as noticed at parenthesis stage in RGN-229 in normal sowing.
