| 摘 要： | 采用完全随机试验设计方法,研究桉树叶水浸提液对水稻、黑麦草、玉米、绿豆4种受体植物种子萌发和幼苗生长的影响,探索外源硅(Si)对4种受体植物受桉树化感胁迫的缓解机制。试验结果表明:(1)在桉树叶水浸提取液处理下,对绿豆的化感作用不显著,对水稻、玉米和黑麦草种子的发芽率、发芽指数、幼苗生长则表现为显著的抑制现象,其中桉树叶水浸提取液对根长抵制作用大于芽;随着桉树叶水浸提取液浓度的增大,4种受体幼苗的根系活力持续下降。(2)加入外源Si能较好地缓解4种受体植物对桉树的化感效应,表现为发芽情况、伸长量、生物量都明显提高,根系活力增强。不同受体植物受桉树化感作用的影响及Si对桉树叶水浸提液胁迫的缓解作用有差异。
