Abstract Salinity stress is a major factor limiting plant growth and productivity
of many crops including oilseed. The present study investigated the identification
of salt tolerant mustard genotypes and better understanding the mechanism of salinity tolerance. Salt stresses significantly reduced relative water content (RWC),
chlorophyll (Chl) content, K+ and K+
/Na+ ratio, photosynthetic rate (PN), transpiration rate (Tr), stomatal conductance (gs), intercellular CO2 concentration
(Ci) and increased the levels of proline (Pro) and lipid peroxidation (MDA) contents, Na+
, superoxide (O2•−
) and hydrogen peroxide (H2O2) in both tolerant and
sensitive mustard genotypes. The tolerant genotypes maintained higher Pro and
lower… More >
