Abstract

Mustard genotypes Panchali and Bhavani (tolerant), and TS-46 and PT-303 (susceptible) were subjected to varied levels of salinity stress (control, 4.0, 8.0, 12.0 dS m−1) to investigate the biochemical basis of salt tolerance during germination. Increase in salt stress resulted in decrease in sugars and phospholipids, and increase in malondialdehyde and phenol content in all genotypes. However, tolerant genotypes showed higher content of sugars, lipids, phenols and lower MDA content as compared to susceptible genotypes.
