摘要:
目前，外来入侵植物南美蟛蜞菊已经造成了严重的生态环境问题。尽管已经有很多研究报道了南美蟛蜞菊快速扩张的机制，但是关于南美蟛蜞菊在低营养环境下依旧能够保持较快扩散能力机制的研究却很少。旨在探讨不同磷环境下丛枝菌根真菌对南美蟛蜞菊快速生长的影响及其机制。结果表明，丛枝菌根真菌与南美蟛蜞菊可以形成良好的共生关系，在低磷环境下，可以明显优化南美蟛蜞菊的生物量分配策略，地下、地上的生物量分配支持最优分配理论。此外，丛枝菌根真菌可以显著提高低磷环境下南美蟛蜞菊叶片中的茉莉酸、赤霉素含量，从而促进植物生长。以上研究结果说明，丛枝菌根真菌可以通过调节植物体内的激素含量而对南美蟛蜞菊的生物量分配策略产生影响，从而促进南美蟛蜞菊在低磷环境下的快速生长与扩张。
