黑穗醋栗亲和性研究

STUDY OF COMPATIBILITY ON BLACK CURRANT

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。

The results showed that Ribes nigrum L belong to self-incompatibility, and other materials were self-compatibility The rate of bearing through self-pollination on Ribes nigrum is zero the pollens through self-pollination the stigma don't germinate, and electrophoresis showed that there does exist a line of special enzyme band of R nigrum L which was distinguished from other species in the C-area of style and stigma
