| 摘 要： | 丛植菌根（AM）真菌和种内竞争均是影响植物种群结构和功能的重要因素，深入研究AM真菌和种内竞争的交互作用，对揭示植物生长规律、生殖动态以及维持种群的稳定性具有深远的意义。基于此，围绕植物种群的种内竞争关系，分别从植物同龄种群和异龄种群2个角度出发，论述了AM真菌在植物幼苗之间、植物成株之间、幼苗与成株之间的竞争过程中发挥的生态学功能，提出AM真菌是调节植物种内竞争的重要机制。反之，地上宿主植物的种内竞争也对地下AM真菌的侵染率和AM真菌的群落结构产生显著影响，二者之间的关系是相互作用、彼此依存的。

| Abstract: | Arbuscular mycorrhizal(AM) fungi and intraspecific competition are considered as the two main factors which affect plant populations structures and stabilities.By the intermediator of plants,the interaction between AM fungi and plant intraspecific competition has become one of the hotspots in ecology,which study on revealing plant growth,reproduction and the stability of plant population.On the basis of this,this study focus on the effects of AM fungi on individual plant in the same ages populations and the... |
