四种植物生长调节剂对茶叶产量与品质的影响

The influence of plant growth regulators on the yield and quality of tea

在茶树生长旺季，采用丙酰芸苔素内酯（propionyl brassinolide）、芸苔素内酯（bmssinolide）、羟烯腺嘌呤（oxyenadenine）＋烯腺嘌呤（enadenine）、复硝酚钠（sodium rtho-nilrophenolate）等4种植物生长调节剂进行处理，探讨其对茶叶生长及品质的影响。田间调控试验表明，供试植物生长调节剂对茶树萌芽没有明显影响，但显著提高了百芽重，从而提高茶园产量，增产达18．41％-20．63％。经室内生化分析，供试植物生长调节剂能影响茶叶中氨基酸、茶多酚、水浸出物等形成，降低酚氨比，从而改善茶叶品质。

The influence of 4 plant growth regulators （oxyenadenine ＋ enadenine, propionyl brassinolide, brassinolide, and sodium rtho-nitrophenolate） on the yield and quality of tea was studied in the field condition. The results showed that spraying plant growth regulators did not influence the budding of the tea trees, but greatly increased 100-bud weight, which resuiting in the increase in the yield and the improvement in quality of tea leaves. Spraying plant growth regulators increased the yield by 18.41% - 20.63% as compared with spraying water.
