Outline
In order to explore the appropriate keeping way of tea plants before closing the garden, using “Baojinghuangjincha 1” as the test material, two autumn management treatments were set up, topping before garden closing (T) and no topping (CK). Samples were collected at germination stage, bud head stage as well as one bud and one leaf stage in spring, and the hormone content was determined. The amino acid components and related gene expression levels at one bud and one leaf stage were determined, and the correlation between hormone content and main amino acid components was analyzed. The results showed that budding density, 100-bud weight, and yield of tea plants in T treatment were extremely significantly increased compared with CK treatment. The determination of endogenous hormones in three periods showed that T treatment mainly affected the contents of auxin and cytokinin, the contents of auxin and cytokinin were positively correlated with the content of major amino acids, and the contents of theanine and aspartic acid were significantly positively correlated with the content of IAA-Ala. T treatment was beneficial to the accumulation of auxin and cytokinin in new shoots of tea plants in spring, promoted the germination and growth of lateral buds of tea plants, increased the yield, and T treatment was also beneficial to the accumulation of major amino acid components, such as theanine, aspartic acid, glutamate, serine, and improved the quality of tea.
