濒危植物珊瑚菜花粉生活力的测定

Studies on Pollen Viability of the Endangered Plant Glehnia littoralis

采用花粉离体萌发法,对珊瑚菜的花粉进行了生活力测定。结果表明:珊瑚菜初花期的花粉萌发率最高,为9.7%;在恒温25℃条件下,以0.6%琼脂+10%蔗糖+0.1%硼酸为离体培养基进行培养,有利于珊瑚菜花粉的萌发;低温(4℃)条件可延长珊瑚菜花粉的寿命,将其进行短期贮藏。

The pollen viability of Glehnia littoralis was studied by pollen germination method in vitra .The results are as follows： The period having the highest germination rate of pollens, which was 89.7%, was the initial bloom stage of Glehnia littoralis. When the temperature was 25 ℃, the most appropriate culture medium of pollen germination was the medium with 0. 6% agar , 10% sucrose and 0. 1% boric acid. The life-span of pollens of Glehnia littoralis could be prolonged, when they were at low temperature （4℃） .And pollens may be short-term stored at this temperature.
