以外源GA_3和ABA处理种子和水稻亲本，研究GA，和ABA对水稻种子萌发及亲本稳上发芽的影响，结果表明，外源GA3处理后引起两者种子内源GA3升高，降低种子内ABA、IAA水平，提高了GA_3/ABA比值；外源ABA处理，引起种子内ABA含量升高，降低GA_3、IAA水平，GA_3/ABA比值减少；种子萌发和穗芽形成过程中GA_3含量、GA_3/ABA比值对比，发现前者小于后者，而种子萌发率与穗芽率相比，前者远远大于后者，表明穗上穗芽形成是一个更为复杂的生理变化过程。

Treating with exogenous GA3 , ABA on seed and parents hybride rice to study different exogenous on change of Endogenous Content in Parents Hybrid Rice Preharvest Sprouting and Seed Germination. The results showed that exogenous GA3 promoted endogenous GA3 content and the ratio of GA3/ABA to increase, and decrease exogenous ABA,IAAcontent. Exogenous ABA made endogenous ABA content increase, decreased exogenous GA3, IAAcontent, and leaded to the ratio of GA3/ABA decreased. Between seed germinating and preharvest sprouting,effect on GA3 content and ratio of GA3/ABA of the former was less than of ...
