赤霉酸涂抹剂对黄金梨产量和品质的影响

Effect of Gibberellic Acid on Yield and Quality of Whangkumbae

[目的]提高黄金梨的产量，改善黄金梨的品质。[方法]共设7组处理，即：不同浓度的赤霉酸与CK。在黄金梨谢花后20d，用各组处理涂抹黄金梨的果柄。研究赤霉酸对黄金梨的产量及品质的影响。[结果]处理①一④（GA3与GA4的混合处理）的梨果增重显著，分别比CK增重15．2～30．2g，其中，以处理②，即2．7％（GA3＋GA4）的梨单果重和小区产量最高，分别为293．5g和49．8kg；处理⑤、⑥（GA3与GA4单独进行处理）的梨果重量与cK无太大差距。经赤霉酸涂沫剂处理的梨果品质较好，以处理②的效果最好。[结论]处理②可以提高黄金梨果实的产量与品质。

[ Objective] The study aimed to enhance the yield, improve the quality of whangkumbae. [ Method] 7 groups treatments were set up, i.e. different concentration gibberellic acid and CK. The fruit stalks were daubed gibberellic acid on 20 d after flowering. The effects of gibberellic acid on yield and quality of whangkumbae were studied. [ Result ] The weight of pears of treatment ①一④ （mixed treatment of GA3 与 GA4 ） increased marked, compared with CK, respectively increased 15. ：2 - 30.2 g, among them, weight and yield of treatment ② reached the maximum, respectively 293.5 g and 49.8 kg; There were no significant differences were found in fruit weight among ⑤, ⑥ and CK treatment. The quality of whangkumbae was better, which treated by the gibberellic acid, among them, treatment ② had the best effects. [ Conclusion] Treatment ② can enhance the yield and quality of whangkumbae.
