采用生物测定的方法,研究了伊贝母(Fritillaria pallidifloraSchvek)鳞茎、地上茎和叶片水浸提液的自毒作用。结果表明,伊贝母各部位浸提液对种子萌发及早期幼苗生长的抑制作用,随浓度升高而增强,同浓度条件下各部位浸提液总体表现为叶片浸提液抑制作用最强,其次是地上茎浸提液,鳞茎浸提液的作用相对较弱。
The bioassay method was used to study the autotoxicity of Fritillaria pallidiflora Schlech’s aqueous extract from bulb, shoot and leaf. The results showed that the inhibitory effect of extracts from all parts of Fritillaria pipiens pallens on seed germination and early seedling growth increased with increasing concentration. Under the same concentration conditions, the extract from all parts showed the strongest inhibitory effect on leaf extracts, Followed by aboveground stem extract, the role of bulb extract is relatively weak.
