| 英文摘要 |
Distinct aberrant gametophytes have developed from the spores of Haplomitrium Rotundifolium. At first, spores were sown in distilled water, and then transferred to 50% Hoagland's solution. Gradually, the spores became swollen, green and floating on the surface of the solution. Cell division soon took place and a triangular structure (Yang 1966) resulted at the end of 6 months. One year later, leafy gametophytes were completed in culture (Yang 1967). Since then, they have been maintaining vigorous growth and green color for almost three years by constant transfers to new media. The rate of their growth is very slow and the size of these a ben ants arc small and have borne no reproductive organs. |
