不同品种茶树矿质元素含量研究

摘要

To understand the mineral elements in different varieties of tea (Camellia sinensis), 17 mineral elements in eight tea varieties including Yunnan Dayezhong, No.43 Longjing and No.6 Zaobaijian, were measured. The results showed that nine elements, such as P, K, Ba, Mn, Cu, were significantly different among varieties, others did not. Black tea varieties usually contain high contents of Cu and K. As a conclusion, mineral elements should be extensively considered in breeding tea varieties.
