摘要: 采用菌丝生长速率法和共毒因子法,测定小檗碱与山豆根、炉甘石、芸薹素内酯、复硝酚钠复配剂对番茄灰霉病的抑制作用。结果表明,小檗碱(0.280 mg/mL)与10%山豆根(2.257 mg/mL)、小檗碱(0.155 5 mg/mL)与炉甘石(0.062 5 mg/mL)复配使用对灰霉病菌抑制效果较佳,小檗碱与芸薹素内酯、复硝酚钠复配能促进灰霉菌生长。电镜观察发现,经小檗碱和山豆根、炉甘石复配处理的灰霉病菌菌丝扭曲、干瘪。田间防效试验结果表明,10%小檗碱可湿性粉剂1 000倍稀释液对灰霉病菌的防效为71.7%,小檗碱与山豆根、炉甘石、复硝酚钠、芸薹素内酯合用均能增加小檗碱对番茄灰霉病的防效。由此可知,小檗碱可与山豆根、炉甘石、芸薹素内酯、复硝酚钠复配用于番茄灰霉病防治。

Abstract: The antibacterial activity of berberine with radix Sophorae tonkinensis,calamine,brassinolide and compound sodium nitrophenolate on Botrytis cinerea was studied by the method of mycelial growth rate and co-toxicity factor. The results showed that both of complex of berberine(0.280 mg/mL) and radix Sophorae tonkinensis (2.257 mg/mL) or berberine(0.155 5 mg/mL) and calamina(0.062 5 mg/mL) had strong inhibition against B. cinerea. However, the mixtures of berberine and brassinolide or compound sodium nitrophenolate could promote the growth of B. cinerea. Scanning electron microscope analysis revealed that the mycelia of B. cinerea manifested abnormity including distortion and collapse. The results of field control experiments showed that the control effect of 10% berberine was 71.7%. Furthermore, berberine combined with radix Sophorae tonkinensis, calamina, brassinolide and compound sodium nitrophenolate could increase the control effect of berberine against Botrytis cinereal. So it could be hypothesized that complex drugs could inhibited the gray mold cell membrane and played an antibacterial effect.
