摘要
对黑龙江省依兰县酸浆根腐病病根及地下茎进行了病原菌的分离鉴定,根据致病菌的形态特征、致病性,结合rDNA ITS序列分析,确定茄镰孢菌〔Fusarium solani(Mart.)Sacc.〕与尖镰孢菌(Fusarium oxysporum Schlecht.)为主要致病菌。茄镰孢菌生长的最适温度为25～30℃,最适pH值为8.0;尖镰孢菌在10～30℃之间均可生长,25℃为最适生长温度,最适pH值为7.0;光照对菌落生长的影响不明显。
The separate identification of pathogens from the disease tissue of Physalis alkekengi L.root rot in Yilan county of Heilongjiang province was carried out in this report.he morphology observation and the results of rDNA ITS sequence analysis revealed that Fusarium solani(Mart.)Sacc.and Fusarium oxysporum Schlecht.were the main pathogenic bacterias.The optimum field temperature was 25-30 ℃,and the most suitable pH value was 8.0 for the F.solani colonies growth.The F.oxysporum could grow with temperature between 10-30 ℃,while 25 ℃ and pH 7.0 is the optimum condition.Light had no significant effect on both main pathogenic bacteria.
