茶树叶片解剖结构与品质性状主成分分析表明,茶多酚含量与游离氨基酸含量的比值、栅栏组织厚度与海绵组织厚度的比值、茶多酚含量、栅栏组织厚度互为正相关,游离氨基酸含量与海绵组织厚度呈正相关,这两组性状互为负相关。15个茶树材料聚为灌木中小叶栽培型、半乔木大叶栽培型、乔木大叶野生型等3类。 The anatomical structure and quality traits of tea leaves showed that the ratio of tea polyphenol to free amino acid, the ratio of palisade tissue thickness to sponge tissue thickness, tea polyphenol content and palisade tissue thickness were positively correlated with each other. The contents of free amino acids and Sponge tissue thickness was positively correlated, the two groups of traits negatively correlated with each other. Fifteen tea trees were clustered into medium-sized shrubs, medium-sized shrubs, and large-leaved trees.
