水杨酸诱导辣椒抗疫病的作用研究
Studies on the Effect of Salicylic Acid Treatment on Resistance of Pepper against Phytophthora Blight
摘要
Abstract
Experiments were carried out to study the induction of systemic resistance by salicylic acid(SA) against phytophthora blight. The results showed that the resistance of against Phytophthora capsici could be significantly improved after the pepper seedlings were treated by SA. Within the range of 0.5-1.0 mM SA, the induced resistance increased gradually with its concentration and showed the strongest protective effects when the concentration was 1.0 mM.However, the induced resistance would gradually be weakened subsequently; 3 days were at least needed for the plants to express systemic resistance, and it could show protective effects till 10th day.关键词
