“New progress has been made in the study of biochemical composition characteristics and genetic diversity of native tea germplasm in Guizhou. Researchers have established a 12 biochemical component determination system based on HPLC, explored the mechanism of the influence of altitude on the biochemical components of tea trees, and verified the hypothesis that inter population variation is the main source of biochemical component variation, providing scientific basis for accurate identification of tea resources, variety breeding, and development of characteristic products.”
