不同茶树品种或品系具有相异的形态特征和生理、生化特性,是构成不同品种的繁殖强度高低、苗期生育状况的差异以及能否获得丰产、稳产和优质的内在因素。近三十多年来,国内已育成的茶树品种达100多个,育种工作者对于育成品种的形态特征、栽培方法和丰产性能等均已作过很多详细报道。然而综合一批茶树品种,集中一地,系统调不同茶树品种或品系具有 Different varieties or strains of tea tree have different morphological characteristics and physiological and biochemical characteristics. They are the factors that influence the reproductive intensity of different varieties, their reproductive status at seedling stage and whether they can achieve high yield, stable yield and high quality. In the recent three decades, there have been more than 100 varieties of tea trees bred in China. Breeding workers have reported in detail about morphological characteristics, cultivation methods and high yield performance of breeding varieties. However, a number of tea varieties integrated, focused on a system of different tea varieties or strains of tea
