以浙江农业大学茶学系种质资源圃的７６个茶树种质资源扦插苗为材料，测定茶树苗期生物产量、光合器官面积与重量、单叶净光合速率、蒸腾速率、气孔导度、细胞间隙ＣＯ＿２浓度和呼吸强度等项目，并进行相关及回归分析，结果表明：茶树种质资源苗期生物产量、光合特性差异显著，茶树苗期生物产量与单株叶面积，单株叶干重呈高度极显著正相关，相关系数分别为ｒ＝０．８５２９（Ｐ＜０．０１）和ｒ＝０．８８５２（Ｐ＜０．０１）；与净光合速率呈中度极显著相关，ｒ＝０．３０３６（Ｐ＜０．０１）；与蒸腾速率、气孔导度、细胞间隙ＣＯ＿２浓度、呼吸强度等的相关性不显著。不同茶树类型的苗期生物产量与光合特性具有不同的相关特点。为此，根据茶树苗期净光合速率、单株叶干重、单株叶面积等性状可进行茶树资源苗期产量的早期鉴定。
Totally, 76 tea germplasm resources cutting seedlings of germplasm resources garden of Zhejiang Agricultural University were used as materials to measure the biomass, the area and weight of photosynthetic organs, net photosynthetic rate of single leaf, transpiration rate, stomatal conductance, The results showed that there were significant differences in the biomass and photosynthetic characteristics of tea germplasm at seedling stage, the biomass of tea plant at seedling stage, the leaf area per plant and the dry weight of leaves per plant (R = 0.8529 (P <0.01) and r = 0.8852 (P <0.01) respectively. There was a moderately significant correlation with net photosynthetic rate, r = 0 .3036 (P <0.01), and had no significant correlation with transpiration rate, stomatal conductance, intercellular CO 2 concentration, respiration intensity and so on. The seedling biomass and photosynthetic characteristics of different tea tree types have different related characteristics. To this end, according to the tea seedling net photosynthetic rate, leaf dry weight per plant, leaf area per plant and other traits of tea resources can be early identification of seedling yield.
