次适温下腐胺对水稻种子萌发的影响

EFFECT OF PUTRESCINE ON THE GERMINATION OF RICE SEEDS UNDER SUBOPTIMAL TEMPERATURE

  • 摘要: 0.01-0.1mmol/L腐胺Putrescine(Put)浸种处理48h,可以促进水稻种子(加粒222)在次适温下(16±1℃)萌发,显着地提高发芽指数和活力指数。但在28℃时对种子萌发无显着影响。进一步研究表明,在次适温下(16±1℃),Put可以促进α-淀粉酶合成,提高α-淀粉酶活性。增加呼吸强度和ATP含量。但在28℃时,Put对种子内α-淀粉酶活性无影响。研究结果表明,Put对种子萌发的影响与温度有关,在次适温下(16±1℃)可促进水稻种子(加粒222)萌发。

     

    Abstract: With different concentrations of Putrescine (Put)for rice-soaking, we investigated its effects on seed germination at sub-optimal and optimal temperatures.The resultls showed that Put-treatment(0.010.1mmol/L)enhanced seed germination and index of germination and rigour of the rice seed at sub-optimal temperature(16±1℃),but no effects at optimal temperature(28±1℃).It was found that the effect of Put on the germination of rice seed was connected with temperature.In mean time,we also found that Put-treatment enhanced the synthesis of α-amylase,increased the ATPcontent and the respiration intensity during seed germination at sub-optimal temperature(16±1℃).
