摘要
用冰核细菌(INA细菌)接种早钟6号枇杷,经不同低温和不同时间处理后,检测IAA、GA3、ABA和ZT4种内源激素的含量变化。结果表明:在低温胁迫下,感染INA细菌后枇杷幼果中IAA含量一直处于较低水平;GA3和ZT含量无明显规律性;ABA含量与ABA/GA3比值试验组的峰值均高于对照,但出现峰值之后,两者均迅速下降,且试验组的下降趋势明显快于对照。
The loquat cultivar Zaozhong 6 (Eriobotrya japonica L. cv. Zaozhong 6) was treated with INA bacteria at different temperatures for various time durations to observe the content change of IAA, GA3, ABA and ZT in the young loquat fruit. The results showed that the content of IAA in the young loquat fruit treated with INA bacteria was always at a low level under stress of low temperature. There was no obvious regularity in the content of GA3 and ZT. The ABA content and the ratio of ABA/GA3 in the young loquat ...
