| 摘 要： | 通过设定不同浓度的BTH和BABA对2年生龙井43进行喷雾处理,探讨两种物质对茶树新梢部分生长指标、茶鲜叶主要品质化学成分的含量和相关代谢酶活性的影响。结果表明,与对照相比,处理后新梢芽长和芽重、含水量、干物质量差异不显著（P>0.05）。鲜叶中多酚类物质、总氨基酸、咖啡碱和可溶性蛋白的含量均有不同程度的提高,75 mg·L-1 BTH处理后含量分别增加了29.32%、49.10%、23.77%、96.34%;400 mg·L-1 BABA处理后含量分别增加了15.75%、45.50%、21.31%、87.18%。可溶性糖含量和酚氨比降低。PPO和GS两种酶的活性明显提高,而POD和PAL的活性相应降低。以上研究初步表明75 mg·L-1的BTH和400 mg·L-1的BABA可以通过调节茶叶的主要化学品质成分和相关酶的活性,在一定程度上改善茶叶的品质。

| Abstract: | The effects of different concentrations of BTH and BABA on growth of tea shoot, quality components and metabolic enzyme activity of leaves were investigated. The results showed that, the bud length and weight, water content, amount of dry matter was not significant compared with control (P>0.05). The content of polyphenols, total amino acids, caffeine and soluble protein were increased by 29.32%, 49.10%, 23.77%, 96.34% after 75 mg·L-1 BTH treatment and 15.75%,45.50%,21.31%,87.18% after 400 mg·L-1 BABA treatment. And yet, the content of soluble sugar and phenol ammonia ratio decreased. The activity of PPO and GS improved obviously, POD and PAL activity decreased relatively. These preliminary results showed that 75 mg·L-1 BTH and 400 mg·L-1 BABA could improve the quality of tea to some extent by adjusting the main components and the activity of related enzymes. |
