人工疏果对黄皮果实品质及部分内源激素含量的影响

以'大鸡心'黄皮为材料,研究了不同程度人工疏果对黄皮果实品质及内源激素含量的影响.结果表明:与对照相比,疏果50%和25%后,黄皮果实中可溶性糖、维生素C、可食率等显著提高,可滴定酸含量显著降低;疏果50%和疏果25%后,黄皮果实种子及果皮的IAA、GA3、ZT含量增加,ABA含量降低.实验表明,人工疏果可以提高黄皮果实的品质,提高果实内促进生长类激素含量、降低抑制生长类激素含量.

Effects of Hand-thinning on Quality and Partial Endogenous Hormone Contents in Wampee Fruits

In this trial,the wampee Clausena lansium(Lour.) Skeels] cultivar 'Dajixin' was used to study the effects of two levels,ie,50% and 25%,fruit-thinning on fruits quality,and partial endogenous hormone contents in fruits,and non-thinning as control.The main results were as follows.The quality fruits of 50% and 25% fruit-thinning treatments in this trail were better than the control.The TSS,total soluble sugar content,vitamin C content,the pulp recovery rate were higher than control respectively.The content of IAA,GA3 and ZT in fruits of 50% and 25% fruit-thinning treatments were higher than those of the control,and ABA lower.This trial showed that hand-thinning could improve the quality of wampee fruits,increase the contents of promotive endogenous hormones,and decrease that of suppressive endogenous hormones.
