| 摘 要： | 引起小麦赤霉病的禾谷镰刀菌(F.graminearum Schw.)的一个单芽管菌株FH_(22-1)在单孢分离的后代中出现与亲本性状明显不同的变异菌株。经鉴定,变异菌株与锐顶镰刀菌(F.acuminalum Ell.＆Ev)相似。经三次连续分离证明,只能从亲本型菌株中分离出变异型菌株,其变异率为3.3-11.5％。

| Abstract: | Variations of spccific charactcrs of single-spore progcnics from a singlc-gcrm-tubc strain of F. graminearum Schw. causing wheat scab appcarcd aftcr singlc-spore isolations. The pcrccntagc of variation was 3.3-11.5%. Variants wcrc distinquishcd from parcnts by amaranthine substratum, short , dense acrial mycclia, slow growth of mycclia, curvcd, slendcr macroconidia, the production of microconidia, chlamydosporcs and slimy pionnotcs, no formation of pcrithccia, and weak virulcnce to wheat, which was similar to F. acumintum Ell & Ev. |
