Abstract
Nongda108 was soaked with exogenous spermidine.Effects of exogenous spermidine on the growth and physiological characteristics of maize seedlings under water logging stress were studied.The results indicated that exogenous spermidine could reduce the yellow leaves per plant and the death rate of maize seedlings under water logging stress;retard the descent of chlorophyll content;maintain the stability of plasmalemma permeability;decrease the production rate of O2-.and the accumulation of MDA of maize seedlings under water logging stress.The ability of anti-water logging stress of maize seedlings was increased by soaking with exogenous spermidine.The optimal concentration of spermidine was 0.4 mmol/L.
