Diversity Analysis of Chlorophyll, Flavonoid, Anthocyanin, and Nitrogen Balance Index of Tea Based on Dualex

The chemical compositions of tea (Camellia sinensis) are affected by numerous factors, such as cultivar, climate, leaf position, and cultivation pattern. However, under the same conditions, mainly determined varieties. Therefore, we investigated genetic diversity tree resources in China to screen excellent germplasm resources. Three index (including chlorophyll index, flavonoid anthocyanin index) nitrogen balance leaves were measured 102 germplasms planted Chinese Tea Plants Improved Variety Germplasm Resources Nursery (CTPIVGRN) Dualex on April 15 2019. Results showed that chlorophyll, flavonoid, contents significantly differed between germplasms. values 2.005, 2.246, 1.599, 1.838, average was 1.922. can be divided into four categories cluster analysis distance threshold 11. These results suggest is rich. This study’s serve a basis for diversified development utilization plant.
