摘要
对茶树９个品种以及红山茶、白山茶两个对照种的叶部形态特征、叶部解剖结构和生化成分进行了综合测定，采用主成分分析、系统聚类、对应分析等数学手段分析品种间的变异性、进化途径及亲缘关系的结果表明：（１）茶树系统演变遵循白山茶→红山茶→茶的演化趋势，并且白山茶和红山茶有较近的亲缘关系；（２）湖南３个茶树品种的进化次序为：城步峒茶→江华苦茶→安化群体；（３）可将茶树的演化划分３个进化层次．
Synthetic mcasurement has been made on morphology, anatomy and chemicalcharacters of
nine varieties of tea plants, and two cemellia spaces as contract(Hongshanchaand
Baishancha). Variance,evolutional line and relationship of the varities have been studidedby
using the methodes of principal conponents Analysis,clustar Analysis. The results show :(1)Tea
plants evolut phylogenetieally as the sequence : Baishancha, Hongshancha, Tea,
andBaishacha has closer relationship with Hongshancha;(2)The evolutional sequence of
threetea varieties in Hunan is : Chengbudongcha. Jianghuakucha, Anhuacha ;(3) The evolution
ofcemellia sinensis plants can be devided into three evolutional tiers.
