| 利用植物的化感作用原理，采用匍根骆驼蓬为供体，探究不同浓度匍根骆驼蓬浸提液对刺萼龙葵种子萌发的抑制作用，以期为刺萼龙葵生物防治提供新的思路和理论参考。采用室内培养皿方法，制备不同浓度（5、10、20、30、40、50 g·L-1）的匍根骆驼蓬水浸提液，以刺萼龙葵为受体，开展种子萌发试验，分析不同浓度匍根骆驼蓬水浸提液对刺萼龙葵种子萌发的影响。结果表明：（1）浸提液浓度为30 g·L-1时，刺萼龙葵种子发芽率、发芽势、发芽指数和活力指数均为0。（2）浸提液浓度为30 g·L-1时，刺萼龙葵种子萌发指标的综合化感效应指数为-1.00。（3）浸提液浓度为30 g·L-1时，其对刺萼龙葵胚根胚芽抑制率为100%，胚根和胚芽综合化感效应指数为-1.00。综上，在匍根骆驼蓬浸提液浓度为30 g·L-1时，其对刺萼龙葵种子的萌发及萌发期胚根和胚芽的生长抑制效果最佳。 |
| 英文摘要: |
| 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. |
