| 摘 要： | 1999年7月云南省元谋县城郊玉米地发现一种玉米新病害,发病面积大约70 hm2.其典型症状表现为植株矮化,节间缩短,叶片密集簇生,叶片上有黄绿相间的条斑。叶鞘上有坏死或腐烂病斑,幼穗腐烂,不实,严重者绝产,颗粒无收。从坏死或腐烂的叶鞘和果穗上可镜检到分生孢子及分生孢子梗。纯化培养后,并按柯赫氏法则进行接种试验,病原鉴定为柔弱无枝孢［Acladium tenellum ( Berk. &; Curt.) Subram. comb. nov.］。本文对病害症状、病原形态、发病情况等进行了详细研究, 确定该病为玉米一种新病害。

| Abstract: | In July, 1999, about 75 hm2 of maize in Yuanmou County of Yunnan Province,China,were infected by a serious disease which led significant yield losses and in many cases almost no yield. The typical symptoms are different from that of the known diseases of maize. Infected maize plants we are stunted, and narrow uprigh leaves with frequently chlorotic striping. Some leaf sheaths showed necrotic spots and ears rot in the later stage. The pathogeny was Acladium tenellum ( Berk. &; Curt.) Subram. comb. nov., a new disease on maize. |
