| 摘 要： | 通过对云南热带、亚热带生长的２５６种蕨类植物ＶＡ菌根的调查，发现蕨类植物ＶＡ菌根营养者所占的比例低于被子植物；在真蕨类植物中，植物具有由ＶＡ菌根营养经兼性ＶＡ菌根营养向自养方向进化的趋势。

| Abstract: | The mycorrhizal states of 256 species of pteridophytes which are naturally distributed in the tropical and subtropical areas of Yunnan (Southwest China) were surveyed . It was found that the percentage of vesicular arbuscular mycotrophic associated with pteridophytes are lower than the angiosperms. The evolutionary trend of filicineae may be from mycotrophism to facultative mycotrophism, and at last to autotrophism. |
