- 摘要:
- 玉米弯孢菌叶斑病是近几年我国玉米生产上发生的一种新病害。本文通过对不同地区病叶标样的病原菌分离与鉴定及病原菌致病力测定, 初步明确了新月弯孢菌Curvularia lunata(Wakker)Boed 是黑龙江省玉米弯孢菌叶斑病的主要致病菌。田间症状观察结果表明, 不同玉米品种上症状表现有明显差异, 根据病斑大小、形状、颜色将病斑分为抗病型(R)、感病型(S)和中间型(M)。
- Abstract:
- Curvularia leaf spot of maize w as a new maize disease that has arisen in north China recentyears .This study result showed that the Curvularia lunata (Wakker)Boed w as a main pathogen inHeilong jiang province .The result of f ield observat ion showed that the disease symptom w as dif ferentobviously among different corns .The disease spot s of curvularia leaf spo t can be divided in to resistanttype(R), sensitive type(S)and middle type(M), acco rding to thei r size , shape and color.
