摘要: 为明确河南丹参产区丹参根腐病病原种类及分布,对河南省禹州、渑池、方城、嵩县4个丹参产区丹参根腐病发病率进行调查,采用组织分离培养法对病原菌进行分离和保存,获得30个病原菌菌株(编号F1—F30),结合形态学、分子生物学鉴方法对病原菌进行鉴定,并通过盆栽接种试验比较不同病原菌的致病力。结果表明,河南丹参根腐病发病率在3.5%~85.0%,其中连作田块发病最重。腐皮镰孢菌(Fusarium solani)、层出镰孢菌(F. proliferatum)和尖孢镰孢菌(F. oxysporum)均能侵染丹参根系,引起根腐病。盆栽接种试验结果表明,不同菌株之间致病力存在差异,其中菌株F21为强致病力菌株,菌株F2和F17为中级致病力菌株,菌株F1、F5、F8、F14、F15为弱致病力菌株,菌株F25为条件性致病菌。综上,引起河南丹参根腐病的病原有腐皮镰孢菌、层出镰孢菌和尖孢镰孢菌,不同产区病原菌分布存在差异,不同病原菌致病力也存在差异性。

Abstract: To clarify the pathogenic species and distribution of root rot of Salvia miltiorrhiza in Henan Province,the incidence of root rot on S. miltiorrhiza in Yuzhou,Mianchi,Fangcheng and Songxian of Henan Province was investigated. In addition,the pathogens were isolated from S.miltiorrhiza root rot by tissue isolation and culture,and 30 pathogenic strains(No. F1—F30)were obtained and identified based on morphological and molecular biological methods. The pathogenicity of different pathogens was further tested by pot inoculation.The results showed that the incidence of root rot of S. miltiorrhiza in Henan Province ranged from 3.5% to 85.0%,with the highest incidence in continuous cropping fields.Moreover,F.usarium solaniF.proliferatum and F.oxysporum could systematically infect the roots of S.miltiorrhiza and caused root rot. The results of pot inoculation tests showed that the pathogenicity of different strains differed,with the strain F21 as a strong pathogenic strain,the strains F2 and F17 as intermediate pathogenic strains,the strains F1,F5,F8,F14 and F15 as weak pathogenic strains,and the strain F25 as a conditional pathogen. In summary,the main pathogens causing root rot disease on S.miltiorrhiza in Henan Province were F.solaniF.proliferatum and F.oxysporum,and the distribution and pathogenicity of the pathogens differed in various production areas
