摘要
１９９２年７～９月对加拿大Ｌｅｔｈｂｒｉｄｇｅ农业研究站田间所产鹰咀黄芪种子进行了检验，结果表明该地所产种子带有Ａｌｌｅｒｎａｒｉａ、Ｃｌａｄｏｓｐｏｒｉｕｍ、Ｅｐｉｃｏｃｃｕｍ、Ｆｕｓａｒｉｕｍ、Ｐｈｏｍａ、Ｓｔｅｍｍｐｈｙｌｉ－ｕｍ、Ｕｌｏｃｌａｄｉｕｍ等属以及一个尚待鉴定中的病原菌。种子带菌率随田间取样时间的后移而逐渐增高。接种试验证明了Ａｌｔｅｒｎａｒｉａ、Ｅｐｉｃｏｃｃｕｍ、、Ｐｈｏｍａ、Ｕｌｏｃｌａｄｉｕｍ和１待鉴定种半知菌等五种病原真菌对鹰咀黄芪种子均有一定程度的致病力。
Some of seedborne pathogens
were isolated from seed of cicer milkvetch(Astagalus ci-cer)in Lethbridge of Alberta,Canada。
They are Alternaria,Cladosporium,Epicoc-cum,Fusarium,Phoma,Steniphylium,Ulorladium and
an unidentified fungus.Therate of seedborne diseases were increased with the stage of seed
ripeness。The inocula-tion experment indicated that Alternaria,Epicoccum,Phoma,Ulocladium
and the u-nidentified fungus were pathogenicity to seed of Astragelus cicer.
