Abstract
Mitigative effect of salicylic acid on salt stress-induced growth inhibition of cucumber seedling and its machanism were studied.The results showed that,under salt stress,salicylic acid could increase the relative water content of seedling,decrease the transportation selectivity of Na +?K + to shoot (S\-\{Na +?K +\}),reduce the content of malon-dialdehyde (product of membrane lipid peroxidation ) and the plasmalemma permeability by promoting the activity of membrane-protective enzymes such as superoxide dismutase and peroxidase,therefore the growth inhibition caused by salt stress were mitigated by exogenous salicylic acid in cucumber seedling.
