Haplomitrium rotundifolium之孢子與配子體之人工培養

Spore germination and leafy gametophyte of Haplomitrium rotundifolium developed in culture

In a previous report on the spore germanation of Haplomitrium rotundifolium (Yang 1966), it was shown that a triangular, thalloid sporeling developed in Hoagland’s solution under controlled condition, in about 87 days. Further development was not observed because of microbial contamination. Spore germination of H. rotundifolium and also H. blumii was attempted again in March, 1967. Spores were gathered from respective fresh specimens. Having been treated antiseptically, they were then planted in the nutrient solution in petri dishes. Except for a few changes which will be described later, the same technique was used previously. The present experiment has shown that the germination of spores of H. blumii commenced readily, but that the later development advanced rather slowly.
