| 摘 要： | 研究喷施多效唑和乙烯利混合剂对妃子笑荔枝内源激素及碳氮营养的影响。试验表明,叶面喷施多效唑和乙烯利混合剂,能有效抑制妃子笑荔枝抽生冬梢,促进花芽分化,提高成花率;喷施药剂能提高荔枝树内源ABA、ZR、ABA/IAA、ABA/GA3、ZR/IAA、ZR/GA3值,降低GA3和IAA含量,提高可溶性糖、淀粉、全氮含量,增加C/N比值,而提高成花率,是解决荔枝暖害问题的一个有效途径。

| Abstract: | The effect of PP333 and ethrel treatment on endogenous hormones and carbon and nitrogen nutrients in Feizixiao Litchi was studied.The results showed that the treatment could inhibit the winter twig growth of Feizixiao Litchi,promote its flower bud differentiation and improve flower formation rate;the treatment could also increase the contents of ABA and ZR,and the ratios of ABA/IAA,ABA/GA3,ZR/IAA,ZR/GA3,decrease the contents of IAA and GA3;the treatment could increase the contents of soluble sugar,starch,and total nitrogen,improve C/N ratio and flower formation rate.It is one of the ways to solve the problem of warmth damage in Litchi. |
