摘要
油菜黑胫病(Phoma stem canker),其病原由强弱两种致病菌(Leptosphaeria maculans/biglobosa)组成。目前,除中国和印度外,Leptosphaeria maculans已是严重制约世界各国油菜产业发展的重要因素,在各大主产区均已造成了严重的经济损失。在中国,油菜黑胫病的发生危害亦呈扩展蔓延趋势,自1999年首次分离鉴定出黑胫病弱致病性病原菌Leptosphaeria biglobosa后,随后短短的十几年,Leptosphaeria biglobosa的发生危害由部分省市扩展到了14个省的42个市(县)。目前,由于Leptosphaeria biglobosa未对我国的油菜造成明显的损失,故而人们没有足够的重视。而其在世界各国的发生危害、扩散蔓延及演化规律显示,Leptosphaeria biglobosa可逐渐被Leptosphaeria maculanske所取代,即Leptosphaeria maculans对我国的油菜及十字花科作物生产构成了威胁。
Phoma stem canker, the pathogens are consist of Loptesphaoria maculans and Loptesphaeria biglobesa. Loptesphaeria maculans becomes the major restrict factor for rapeseed industry development worldwide except China and India, which caused serious economic losses in most of the major production areas. We firstly identified Loptesphaeria biglobesa existed diseased plants in 1999 and the occurrence and damage caused by Loptesphaeria biglobesa showed sprawling trend in China, the damage areas expanded to 42 counties of 14 provinces in just dozens of years. But for it did not cause significantly yield loss, there were no enough attention to Phoma stem canker. Study on the occurrence, epidemic and evolution regularity of Phoma stem canker worldwide,we are afraid of Loptesphaeria biglobesa replaced by Loptesphaeria maculans gradually, Loptesphaeria maculans threats to oilseed rape and other cruciforous crops of China.
