【摘要】 在吉林省内采集甜椒炭疽病病样,经分离、纯化、观察,确定黑色炭疽菌Colletotrichum capsici(Syd．) Butl．为主要病原菌,并以此作为接种源,对接种液浓度、接种时期、接种方法、接种后温度、湿度、调查时间、调查标准等进行了一系列研究。最后确定用3×106 个/ml的孢子悬浮液,在成熟红果期采用离体果针刺法接种,接种后温度27±1℃,遮光保湿3d,保持相对湿度(RH)为95-100％,7d后调查病情指数,进行抗、感评价。更多还原

【Abstract】 The anthracnose samples of sweet pepper collected in Jilin province were isolated, purified and investigated . It found that Collototrichum capsici (Syd) Butl was the main pathogen of Jinlin province. This pathogen was inoculated on harvested red fruit by injected inoculation. The research showed that the best conditions of inoculation were the temperature of 27+1℃, keeping RH 95 - 100% for 72h in dark, the concentration of 3 × 106spore/ml.更多还原
