摘要
在调查天目山地区柳杉瘿瘤病发生情况的基础上,通过分析该病发生的不同影响因子和病原菌孢子的产生、释放、传播和侵染过程,确定柳杉瘿瘤病为寄主主导性病害,病害的发生危害受树体的生长势、树龄、立地条件等多种因素影响,海拔高度在1 000 m和100年生以上的柳杉感病指数出现最大值;病原菌孢子传播受气温、降水等气候因子影响,孢子的释放飞散高峰期在6月上旬至7月上旬。
On the basis of survey on the gall diseases in the Mount Tianmu, this research analyzed various determinants of the gall＇s occurrence and the process of pathogenic fungus spore emergence, release, spread and invasion, and defined gall diseases as host dominant diseases. This disease could be affected by cryp- tomeria＇s growing situation, age and stand conditions. When the altitude was more than 1 000 m and cryp tomeria was more than 100-year-old, there would be maximum susceptibility index. Pathogen spores spreading speed could be affected by climate aspects such as air temperature, rainfall and so on. Spores＇ releasing and scattering peak was between early June and middle July.
