| 对一种引起盾叶薯蓣叶、茎呈暗绿色至黑褐色水渍状软腐的病害进行了调查 ,并作了鉴定。结果明确其为灰葡萄孢菌 (Botrytis cinerea Pers.ex Fr )引起的一种新病害 ,根据症状和病原鉴定将该病称为盾叶薯蓣灰霉病。该病原菌生长温度 0～30℃ ,最适生长温度 10～ 2 5℃。病害在每年春季、夏初和秋末 ,雨水多的年份发生严重。 |
| 英文摘要: |
| The gray mold disease of Dioscorea zingibernsis, caused by Botrytis cinerea Pers. ex Fr., was identified through a survey of the disease symptom and occurrance. The leaves and stems looked from dark green to dark brown and rot were infested by the pathogen. The pathogen could grow between the temperature of 0-30℃, the optimum temperature range was 10-25℃.
