摘　　要：室内对岷山红三叶草种带真菌的初步检验中,共检出三叶草叶斑匍柄霉(Stemphylium sarciniforme、三叶草霜霉菌(Peronospora trifoliorum、三叶草单胞锈(Uromyces trifolii.轮枝孢(Verticillium sp.细交链孢(Alternarialenuis,镰孢(Fusarium spp.、茎点霉(Phoma spp.、灰葡萄孢(Botrytis cinerea、青霉(Penicillium spp.、匍枝根霉(Rhizopus stolonifer、曲霉(Aspergillus spp.、芽枝霉(Cladosporium sp.、长蠕孢(Helminthosporium sp.、13种真菌的种或属。这在甘肃均属首次检出,后9种在国内也未见有报道。证明种子带病是许多病原真菌远距离传播的重要途径;混杂在种子间的病株残体也是许多病原真菌的重要携带者。经消毒处理的种子,其携带真菌率和各种真菌的检出率明显降低。对轮枝孢等,应进一步研究,严格杜绝其蔓延为害。Thirteen species or genera of fungi have been found when the red clover(Tri jolitum pratense L.)seed were examined in laboratory,namely:Stem phylium sarcinljorme.Peronospora trijoliorum,Uromyces trijolii,Verticillum sp.,Ahernaria tenuis,Fusarum spp.,Boirytis cinerea,penicillium spp.,Rhizopus stolonijer,Aspergillus slap.,Cladosporium sp.and Helminthosporium sp.,It is first time to find those fungi carried by red clover seed in Gansu Province,the last nine kinds of fungi have not been found in red clover seed in Chine before the test proved that the transmission of fungus by seed is an important way,and the wreckage of disease plant mixed in seed is a main carrier.Seed disinfeeting can reduce the ratio of disease and fungal check-up.Further research should be done in Verticillium ect。to stop the spread and damage.
