对来自波兰及英国的2个相同品种的油菜种子样品进行了健康测试,并重点观察了油菜黑胫病病原菌(Letosphaeriamac ulans/Phomalingam)感染的程度及菌系类型.结果表明来自2个国家的种子都一定程度受微生物感染,品种间差异不大,所检测到的较多的菌属为Alternaria,Fusarium及Penicillium.黑胫病病原菌感染的百分率波兰种子样品平均为0.5%,英国种子样品平均为0.6%,菌系鉴定表明,7.1%的波兰株系及12.3%的英国株系为强致病的Tox+类型.此外,还发现健康测试前种子表面消毒可提高黑胫病病原菌的检出率.
Health tests were conducted on two rapeseed seeds of the same species from Poland and the United Kingdom, and the degree of infection and the strain type of Letosphaeria macula / Phomalingam were mainly observed.The results showed that seeds from two countries Were all affected to some degree by microorganisms, and there was no significant difference among the cultivars.Among the tested isolates were Alternaria, Fusarium and Penicillium, the percentage of pathogen infection of blackleg was 0.5% on average in the seed samples of England and 0.6 % And strain identification showed that 7.1% of the Polish lines and 12.3% of the UK lines were strongly pathogenic Tox + types, and surface disinfection of seeds prior to health testing was found to increase the detection rate of blackleg pathogen.
