摘要
黑龙江省严寒而干燥的气候 ,极不利于蕨类生长。但野生的 90余种蕨类 ,不但能完成营养生长和生殖生长 ,而且长势强劲 ,生长量大 ,因此具有特殊的生理生态学意义。本文首次报导了黑龙江野生拟蕨类和真蕨类共 2 2科 38属 67种 (含 3亚种 )的孢子成熟期。表明大多数种类的孢子都在 7月中旬至 8月中旬成熟 ,水生真蕨类后延 2 0天左右 ,楔叶类和旱生类孢子发育期较为特殊。
The severe cold and dry climate is not beneficial to the growth of Pteridophyte in Heilongjiang of china. More than ninty kinds of wild Pteridophyte not only can finish the vegetative growth and reproductive growth, but also they can grow stongly and humberously. So this research has a particular sigaifilance of physiological ecology. It is first reported that there are about 22 familias,38genera,67species (embrace 3 subspecies) of the wild Pteridophyte's and fern's spore mature period in this article. This indicate most of those kinds are mature from the midst of July to the midst of August,but the aquatic Pteridophyte delay twenty days,especially it is diffirent in Sphenopsids and Xeric spore. We also analyze briefly the relationship between the ecological factors and the spore mature period in this article.
