Effect of Salinity Stress on Growth, Sugar Content, Pigments and Enzyme Activity of Rice

V/FM), photon yield of PSII (φPSII), non-photochemical quenching (NPQ) and net photosynthetic rate (Pn) in the stressed seedlings were inhibited, leading to overall growth reduction. The positive correlations between chlorophyll a content and Fv/Fm, total chlorophyll content and φPSII, Pn as well as Pn and leaf area were found. Sugar content in shoots had a significant increase under salinity stress. The starch content of roots seedlings decreased NaCI stressed seedling. The contents of total, reducing and non reducing sugars increased in roots.
