title: [The effect of exogenous glucose, fructose and NO donor sodium nitroprusside (SNP) on rice seed germination under salt stress].
abstract: The effects and the relationship between soaking rice seed of exogenous glucose, fructose and nitric oxide (NO) donor sodium nitroprusside (SNP) on the seed germination under salt stress were investigated. The results showed that employment of exogenous fructose, glucose and NO donor SNP could significantly promote the germination index and the early germination rate of rice seed under salt stress. Also, SNP pretreatment enhanced endogenous glucose and fructose contents. Effects of exogenous glucose and fructose combined with different concentrations of SNP on the rice seed germination and seedling growth under salt stress were surveyed. The results also showed that there existing positive effect of application of glucose plus SNP on the rice seed germination in comparison with existing a few negative effects of fructose plus SNP pretreatment. Additionally, the alleviation of inhibition of early rice seedling growth under salt stress by SNP could be modulated by glucose and fructose pretreatment, also the effect of glucose was stronger.
