| 摘 要： | 正雍菜(Ipomoea aquatica Forsk.),俗称空心菜,为旋花科(Convolvulaceae)甘薯属(Ipomoea)植物,1年或多年生草本,其嫩茎和叶可食用,有药用价值,在我国南方普遍种植。2015年5月课题组在云南红河州进行病害调查时,在多个雍菜种植田中发现一种新病害,发病快且蔓延迅速,主要为害叶片,严重的田区发病率达54%,严重威胁当地雍菜的产量与质量。为明确病原,我们对田间采集的病样进行了分离培养,并对得到的菌株进行致病性

| Abstract: | In 2015, symptoms of leaf spot were observed on water spinach (Ipomoea aquatica) in fields in Jianshui County,Hani-Yi autonomous prefecture of Honghe, Yunnan Province, China. The causal pathogen was identified as Myrothecium roridum based on the morphological characteristics, pathogenicity test, and molecular identication. Host range of this pathogen was evaluated, and its pathogenicity to 10 plants was significantly different with higher virulence to eggplant and water spinach. To our knowledge, this is the first report of M. roridum causing leaf spot on I. aquatica in China. |
