春兰种子非共生萌发的研究

对春兰种子进行了非共生萌发。培养基中使用葡萄糖时葫发率高于蔗糖；种皮经过手术刀片切割的种子5个月后萌发率达到22．4％；使用0．5％NaOCl溶液对种子进行不同时间的处理，在4～6min时得到了最高的葫发率。种子预处理是提高春兰萌发率的关键，种皮是抑制萌发的主要原因之一。

Seed Germination of Cymbidium Goeringii in Asymbiotic Culture

The seeds of Cymbidium goeringii were germinated in asymbiotic culture. The effect of the glucose is better than that of the sucrose. Five months later, the germination is 22. 4% when the embryos were excised with a scalpel. The seeds were bleached in 0. 5% NaOCl solution for a series of time, the highest germination is obtained when the bleaching time was 4-6min. The bleaching and the stratification are vital to the germination of the Cymbidium goeringii seeds, and the seed coat is one of the important factors of inhibition in the germination.
