摘要
为了了解芒萁对几种豆科植物的化感作用,测定了猪屎豆、山毛豆、木豆的种子在芒萁水提液的培养下的发芽率、发芽速率、化感效应指数以及在芒萁生长地播种试验的出苗率。结果表明,芒萁水提液浓度达到0.2gFw/ml时对木豆种子的发芽率影响显著。山毛豆与猪屎豆种子的发芽率与对照相比差异均不显著,分别达到89.0%和96.0%。播种试验中猪屎豆和山毛豆的出苗率较高,分别为82%与71%。木豆种子受芒萁的化感作用较为明显,山毛豆次之,猪屎豆较轻微。
In order to understand allelopathic effects of Dicranopteris dichotoma （Thunb.） Berhn on several leguminous plants, germination rate, germination speed and allelopathie effect index of erotalaria, tephrosia and pigeonpea under cultivation of Dieranopteris diehotoma （Thunb.） Berhn water extract were researched and measured the seedling emergence in Dicranopteris dichotoma （Thunb.） Berhn habitat. The results showed that ： the impact of pigeon pea seed germination rate was significantly when Dicranopteris dichotoma （ Thunb. ） Berhn water extract concentration was 0.2g Fw/ml ; Tephrosia and erotalaria＇ s seed germination rates comparing with CK were not significant and they were up to 89.0% and 96.0% respectively. Seedlings emergence of erotalaria and tephrosia were higher than that of pigeonpea in seeding trials, and were 82% and 71% respectively. The allelopathy of pigeonpea seed by Dicranopteris dichotoma （Thunb.） Berhn were more obvious, tephrosia fol- lowed and erotalaria was minor.
