| 摘 要： | 在不添加任何外源激素的条件下，用水来隔绝空气，即在试管中沉水条件下培养狭翅巢蕨(Neottopteris antrophyoides (Christ) Ching)的孢子，首次成功地诱导出极端简化的雄性配子体，简化程度几乎与被子植物的花粉粒相当，只由1个营养细胞、1条假根和1个精子器组成。本文讨论了在高等植物生活史系统演化方面，环境因素可能起到的作用。

| Abstract: | Without any extra hormone, by separating the air to the spores, the spores of Neottopteris antrophyoides in liquid culture, the first successful induction of N. antrophyoides (Christ) Ching has been realized and the male gametophyte of simplification is almost the same as pollen grain that is in composition of one nutritional cell, one rhizoide and one antheridium. This article discussed the possible role in the evolution of environmental factor in the history of the system of high class plant life. |
