| 摘 要： | 大田试验结果表明，水杨酸叶面喷雾可减轻芒果炭疽病的发生，100—200mgL-1均有极显著的效果，病情指数分别比对照下降了23％－41．1％，以浓度为100mgL-1的效果最好，而在马铃薯培养基（PDA）中平板培养时，100mgL-1水杨酸对芒果炭疽菌菌丝生长和孢子萌发均无抑制作用．因此认为，水杨酸处理芒果后感病指数下降，是由于水杨酸处理提高了芒果幼果的抗病性，即幼果产生了诱导抗性而引起的．

| Abstract: | Mango(Mangifera indica L. cv. Zihua) inflorescences were treated with salicylic acid at 0, 50, 100, 150, 200 and 250 mg L-1. The results indicated that the disease index of mango fruitS caused by Colletotrichum gloesporioides was decreased significantly when the inflorescences were treated with salicylic acid loo mg L-1. salicylic acid had no inhibitory effect on the spore germination and the colony growth. It may be concluded that salicylic acid could induce mango fruits to have the effect resistant to Colletotrichum gloesporioides. |
