Effects of the extract of Peganum nigellastrum on seed germination of Solanum rostratum
摘要
Abstract
Based on the principle of plant allelopathy,Peganum nigellastrum was used as the donor to explore the inhibitory effects of different concentrations of P.nigellastrum extract on the seed germination of Solanum rostra-tum,aiming to provide new ideas and theoretical references for the biological control of S.rostratum.Different con-centrations(5,10,20,30,40 g·L-1,and 50 g·L-1)of aqueous extracts of P.nigellastrum were prepared u-sing an indoor petri dish method,and seed germination assays were carried out with S.rostratum as the receptor.The results showed that:(1)When the extract concentration was 30 g·L-1,the germination rate,germination po-tential,germination index,and vitality index of S.rostratum seeds were zero.(2)When the extract concentration was 30 g·L-1,the comprehensive allelopathic effect index of seed germination of S.rostratum was-1.00.(3)When the extract concentration was 30 g·L-1,the inhibition rate of radicle and germ of S.rostratum was 100%.The compre-hensive allelopathic effect index of radicle and germ was-1.00.In summary,when the P.nigellastrum extract con-centration was 30 g·L-1,it had the best inhibitory effect on the germination of S.rostratum seed and the growth of radicle and germs during germination.关键词
