Diversity analysis of the main morphological traits of tea plant flower and its biochemical components

The diversity of the main morphological traits of tea plant flower and its biochemical components were analyzed.The results showed that the morphological traits of tea plant flower keep relatively stable in one tea variety and have a large aberrance between different tea varieties,and its diversity in Chinese tea cultivar was more abundant than that in Japanese tea cultivar.When the variability of weight of 100 tea flowers was high its diversity was abundant.The content of biochemical components in tea plant flower also had an abundant diversity.The content of water extract was(53.78%±4.57%),tea polyphenols(10.78%±2.25%),free amino acid(2.60%±0.51%),caffeine(1.42%±0.22%),soluble carbohydrates(3.80%±(1.07%).) The aberrance coefficient of the content of water extract and caffeine in tea plant flower was lower,while that of soluble carbohydrates and tea polyphenols was higher.Compared with tea fresh leaves,the content of water extract and water percentage in tea plant flower was higher,and the content of soluble carbohydrates was a little higher than that in tea fresh leaves.The content of free amino acid was equivalent to that in tea fresh leaves.The content of caffeine in tea plant flower was lower than that in tea fresh leaves.The content of tea polyphenols was much lower than that in tea fresh leaves.
