| 摘 要： | 分离鉴定结果表明,甘肃豌豆根病病原真菌为豌豆丝囊根腐霉(Aphanomyces euteiches Drechs),根串珠霉(Thielaviopsis basicola(Cerk & Br.Ferr.),终极腐霉(Pythium ultimum Trow)尖孢镰刀菌(Fusarium oxysporum Schlecht),丝葚霉B(Papulospora sp. B),腐皮镰刀菌(Fusarium solani(Mart)Sacc.),黑色不产孢菌(Black steile fungus),镰刀菌(Fusarium sp.),丝葚霉A(Papulospora sp.A),丝核菌(Rhizoctonia solani kühn)。10种病原真菌的总侵染株率91.3%,其中豌豆丝囊霉侵染株率62.5%,其余9种病原真菌侵染株率37.3%。分别用豌豆丝囊根腐霉,根串珠霉、终极腐霉、尖抱镰刀菌、丝葚霉B、腐皮镰刀菌、黑色不产孢菌、镰刀菌、丝葚霉A、丝核菌给豌豆植株茎基部接菌,病情指数分别为84.4、61.5、45.0、51.6、80.1、68.3、51.7、50.9、41.6、20.4。植株干重较对照减少依次为56.8%、47.0%、44.6%、36.7%、22.0%、12.2%、20.0%、8.8%、10.2%、24.0%。

| Abstract: | The results showed that there were ten pathogenic fungal in main peas producing regions in Gansu province. Were Aphareomyces euteiches Drechs,Thielaviopsis basicola (Cerk& Br.)Ferrarir,Pythium ultimum Trow,Fusarium ozysporum Schlecht, Papulospora sp.. B, Fusarium solani(Mart)Sacc.,Black steile fungus,Fusarium sp.,Papulospora sp. A,Rhixoctonia solani Kuhn. The percentage of peas plants infected by all these pathogenic fungal attained 91.3%,in which 62.5% by Aphanomyces euteiches and 37.3% by nine. |
