Abstract
Acclimation refers to the process by which plants adapt to the environment. This study was to illustrate the effect of acclimation length on the metabolic profile of tea leaves. In this study, 32 long-acclimated tea varieties in Shandong Province and 61 ST varieties were used as materials, and the metabolites of tea plants were detected by using UPLC-MS/MS method. The results showed that the accumulation of flavonoids, organic acids, and alkaloids in long-acclimated tea plants was higher than that in ST plants. In contrast, the accumulation of phenolic acids, lipids, and amino acids showed an opposite trend. In long-acclimated tea varieties, Camellia sinensis cv. Lucha11 (LC11), LC24, and LC30 showed high flavonoids, phenolic acids, organic acids, and alkaloids, which were important metabolites and related to tea quality. This study provides a theoretical basis for understanding the effect of environment on metabolism of tea plants and guides the breeding of new tea varieties with high quality or special flavor.
