喷施溴氰菊酯对茶树主要特征性次生代谢物含量的影响
Effect of Deltamethrin on the Main Secondary Metabolites in Tea Plant(Camellia sinensis)
摘要
Abstract
This study investigated the effect of different concentration of deltamethrin on the main secondary metabolites in tea leaves. The results showed after spraying deltamethrin at three concentrations for two days, the polyphenols in leaves was significantly lower than controls. In the higher deltamethrin concentration treatment, the larger reduction was happened. However, the maximum drops in recommended concentrations group and low concentrations group (19.4% and 20.3%) were both happened on the 8th day after spraying. For the theanine analysis, treatment after 2 to 8 days, theanine in the leaves of the 3 Treatment groups were obviously lower than that of the control group. Also theanine reached at the maximum drops(22.3% and 18.3%) on the 8th day after spraying both in the high and low concentrations group. At last, in the 2-day-treatment and 4-day-treatment, the content of caffeine went up remarkably in low concentrations group. However, the content of caffeine in the tea leaves was obviously lower than that of control group which was found both in the high concentrations group and recommended concentrations group. In general, three main secondary metabolites were shown little changes in different concentrations compared with the control group treatment after 10 days.关键词
