Abstract
The effect of simulated acid rain with different pH values(2.0,2.5,3.0,3.5,4.0,4.5,5.0 and 6.5) on seed germination and seedling growth in Dimocarpus longan,and the effect of exogenous nitric oxide donor sodium nitroprusside on seed germination and physiological characteristics of longan under acid rain stress at pH 3.5 were investigated.The results showed that longan seed germination was significantly inhibited by simulated acid rain with pH values less than 4.0,and the effect of simulated acid rain with pH 5.0 on germination of longan seeds was little.Low concentration(0.25 mmol/L) of sodium nitroprusside could enhance germination rate and germination vigor of the longan seeds under acid rain stress at pH 3.5,decrease the accumulation of malondialdedyde,and increase root activity of longan seedling.However,excess sodium nitroprusside(1.00 mmol / L) had stress effect on longan seedling,resulting in decreased germination rate and germination potential,declined root activity,and increased malondialdedyde contents.
