Abstract

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.

Key words: BTH, BABA, tea plant (Camellia sinensis), growth, quality components, enzyme
