Abstract
Chlamydospores of Fusarium solani f. sp. cucurbitae, F. solani f. sp. phaseoli and F. solani f. sp. pisi formed in soil were recovered at intervals and examined by electron microscopy. Cell wall material outside the newly formed chlamydospore cell wall gradually disintegrated. Protoplasts of chlamydospore cells lyse without prior penetration of the cell wall by microorganisms. The mechanisms of lysis of chlamydospores of F. solani in soil are discussed.
摘要
定期回收土壤中形成的茄腐镰刀菌南瓜专化型、菜豆专化型和豌豆专化型的厚垣孢子，并通过电子显微镜进行检查。新形成的厚垣孢子细胞壁外的细胞壁物质逐渐分解。厚垣孢子细胞的原生质体在没有微生物预先穿透细胞壁的情况下就会裂解。本文讨论了土壤中茄腐镰刀菌厚垣孢子的裂解机制。
