| 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 rostratum, aiming to provide new ideas and theoretical references for the biological control of S. rostratum. Different concentrations (5, 10, 20, 30, 40 g·L-1, and 50 g·L-1) of aqueous extracts of P. nigellastrum were prepared using 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 potential, 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 comprehensive allelopathic effect index of radicle and germ was -1.00. In summary, when the P. nigellastrum extract concentration 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. |
