１）人工授粉实验表明，去雄自花授粉处理，野生种兴安茶子的座果率为零，栽培品种的座果率在３０％～５０％之间。实验材料自花授粉座果率低于自然授粉和异花授粉。２）荧光法表明，兴安茶子不去雄套袋处理，在柱头上产生一黄色荧光，花粉不萌发。去雄套袋自花授粉处理，花粉萌发，但花粉管没能进入子房，中途停止生长，栽培品种花粉在柱头上都能萌发，进入子房。３）各材料之间，过氧化物同工酶酶谱有很大的共同部分，彼此之间也存在着差异。兴安茶子花柱柱头部分在Ｃ〔５５．２（３４．１）〕有一明显区别于其它栽培品种的一条特殊谱带。
1) artificial pollination experiments show that self-pollination to the male self-pollination, the wild seed Xingning Andean fruit rate is zero, the cultivars of fruit set in 30% to 50%. Experimental materials self-pollinating fruit rate is lower than the natural pollination and cross-pollination. 2) Fluorescence method showed that Xing’an tea curd does not go through the process of bagging, and produces a yellow fluorescence on the stigma. The pollen does not germinate. To the male bagging self-pollination treatment, pollen germination, but the pollen tube failed to enter the ovary, half-way to stop the growth of cultivars pollen germination in the stigma, into the ovary. 3) There is a big common part between peroxidase isoenzymes in different materials, and there are also differences among them. There is a distinct band at C [55.2 (34.1)] distinctly different from the other cultivars in the stigma of the tea branch of the Xing’an tea.
