以几种化合物作为诱抗剂,采用土壤处理和种子处理的方法对甜瓜枯萎病进行诱导抗性研究。结果表明,以0.1、0.5mmol/L水杨酸及4mmol/L草酸处理土壤的诱抗效果较好,相对防效分别达70.0%、51.3%和65.1%;以2mmol/L草酸、1mmol/L及0.5mmol/L水杨酸浸种处理的诱抗效果较好,相对防效分别达55.5%、48.9%及40.0%。
Several compounds were used as inducers to induce resistance to Fusarium wilt in soil by using soil treatment and seed treatment. The results showed that the induction of soil with 0.1,0.5 mmol / L salicylic acid and 4 mmol / L oxalic acid was better than that of the control. The relative control efficiency was 70.0%, 51.3% and 65.1% And 0.5 mmol / L salicylic acid, the relative anti-efficacy was 55.5%, 48.9% and 40.0%, respectively.
