茶树是一种异花受粉植物,在长期的自然受粉情况下,植物学形态和生物学特性都发生了广泛的遗传变异,因而形成了各个生态条件下的不同群体品种。每一个群体品种不同个体之间也表现出多样性,这些多样性是由于茶树个体之间的不同相对性状在遗传上的反应。性状表现的多样性,就茶树本身来说,是一种适应性的结果,这种适应性就人们所需要的经济性状来看, Tea tree is a cross-pollination plants, in the long-term natural powder situation, the morphological and biological characteristics of plants have undergone a wide range of genetic variation, thus forming a variety of ecological conditions in different groups of varieties. Diversity is also shown between individuals in each group of breeds due to the genetic response of different relative traits among individuals in the tea tree. The diversity of traits, as far as the tea tree itself is concerned, is an adaptive result. In view of the economic traits people need,
