摘要
[目的]测定芦笋不同组织浸提液对辣椒的化感效应。[方法]以辣椒为侵体,通过测定芦笋不同部分水浸提液对辣椒种子萌芽和幼苗生长的影响,研究芦笋对辣椒的化感效应。[结果]芦笋地上部和地下部组织水浸提液对辣椒种子发芽率、发芽指数均表现出抑制作用;高浓度芦笋地上部和地下部组织水浸提液对辣椒幼苗的生长及叶绿素含量均具有抑制作用,而低浓度浸提液具有促进作用。芦笋不同组织部位水浸提液的化感作用强弱不同,地上部分水浸提液化感作用明显强于地下部分。[结论]该研究为选择芦笋的间作作物及其秸秆的再利用提供了依据。
[Objective] To discuss the allelopathic effect of water extracts from different parts of Allelopathy of Asparagus officinalis L.on hot pepper.[Method] Using hot pepper as the receptor,effect of water extracts from different parts of Asparagus officinalis L.on seed germination and seedling growth were determined,investigating the allelopathy of Asparagus officinalis L.to hot pepper.[Result] Water extracts of aboveground and underground parts of Asparagus officinalis L.showed inhibitory effect on germination rate and germination index of hot pepper.High concentration water extracts all showed inhibitory effect on seedling growth and content of chlorophyll,while low concentration ones presented facilitating effect on them.In addition,allelopathic effect of water extracts from above ground of Asparagus officinalis L.was stronger than that from under ground.[Conclusion] This work is of considerable value for selection of interculture of Asparagus officinalis L.and reuse of straw of it.
