龙牙百合为湖南省邵阳市的特色经济作物之一,随着栽培面积不断扩大,其病害发生日趋严重,尤其在田间生长后期鳞茎易出现褐变、腐烂、植株枯死等症状,严重影响百合生长,已成为遏制龙牙百合生产的重要因素之一。对湖南省百合生长期鳞茎腐烂病的病原至今未见报道。受隆回县科技局委托,我们对该县鳞茎腐烂病病原进行了形态学和分子生物学鉴定。研究结果为该病害的防治奠定了基础。
As one of the special economic crops in Shaoyang City of Hunan Province, Asparagus Lilium is becoming more and more serious with its growing area. Especially in the late growing stage, the bulblets are prone to browning, rotting and withered plants, which seriously affect the growth of lily , Has become one of the important factors to curb the production of Aral Lily. So far, no reports have been reported on the pathogen of bulb rot in lily growing stage in Hunan Province. Commissioned by the Longhui County Bureau of Science and Technology, we conducted a morphological and molecular biological identification of the pathogen of bulb rot in the county. The results laid the foundation for the prevention and treatment of the disease.
