Photosynthetic mechanism of tea yield and quality affected by different habitats

doi:10.13287/j.1001-9332.201811.029

Abstract

Abstract: To understand photosynthetic mechanism of tea yield and quality, an experiment was conducted with four different typical habitats, including three intercropping patterns (S₁:Osmanthus-Tea, S₂:Michelia-Tea, S₃:Osmanthus-Michelia-Tea) and a control (CK) at Changsha Agricutural Observation Station of Chinese Academy of Sciences. The photosynthetic physiological and ecological characteristics of tea yield and quality were examined. The results showed that the habitats S₁, S₂, S₃ reduced the leaf temperature (TL), photosynthesis active radiation flux (PAR), net photosynthetic rate (P_n), transpiration rate (T_r), and stomatal conductance (g_s), as well as the tea polyphenol content. Habitats S₁, S₂, S₃ significantly increased leaf relative humidity (RHS), total amino-acid content of tea, and the yield and quality of tea, with a pattern of S₃>S₁>S₂>CK. The leaves in habitats S₁ and S₃ could be made into high-grade green tea and famous green tea respectively. Comprehensive indicators showed that habitat S₃ is an ideal intercropping pattern for high quality and high yield of tea garden.
