摘要
初步研究结果表明:雪松枯梢病的病原菌是聚生小穴壳菌DothiorellagregariaSacc;病菌生长最适温度为25~30℃;单糖、双糖、多糖均可作为良好碳源被病菌吸收利用;人工室内接菌条件下,该病还可侵染毛白杨、核桃和沙兰杨枝条;在河南每年3月中下旬开始发病,7月中下旬达到发病高峰。
The preliminary research results showed that the top blight of cedar was causedby Dothiorella gregaria Sacc.The best temperature for the growth of the pathogen rangedfrom 25℃ to 30℃;The pathogen can use monosaccharide,disaccharide and polysaccharideeasily.Under inoculated conditions,the branches of chinese white poplar,walnut and sha-lan poplar all can be infected.The disease rose in middle and late and did the most seriousdamage in middle and late July every year.
