研究了影响黄瓜茄病镰刀菌纯培养产生厚垣孢子的几个因素。液体培养基中不含葡萄糖有利于大分生孢子的裂解和厚垣孢子的形成。低pH和向培养基中添加氯化铵都减少了大分生孢子的裂解并抑制厚垣孢子的形成。在缺乏葡萄糖的培养基中形成的厚垣孢子是由大分生孢子产生的，其方式类似于它们在土壤中的形成。通过光学显微镜和电子显微镜对其进行了检查。当被放入自然土壤中时，它们就像是生存结构。
A study was made of several factors affecting the production of chlamydospores byFusarium solanif.cucurbitaein pure culture. Lysis of macroconidia and chlamydospore formation is favoured by the absence of glucose in liquid culture media. Both low pH and addition of ammonium chloride to the culture medium reduces lysis of macroconidia and inhibits chlamydospore formation. Chlamydospores formed in media lacking glucose were produced from macroconidia in a manner resembling their formation in soil. They were examined by light and electron microscopy. When placed into natural soil, they acted as survival structures.
