摘要： 本文报告镰孢霉属（Fusarium）4个种产孢细胞的发育形态。腐皮镰孢（Fusariumsolani），尖镰孢（F.oxysporum）和串珠镰孢（F.moniliforme）产孢细胞为瓶梗型；而半裸镰孢（F.semitectum）为瓶梗型和多芽产孢细胞型。瓶梗型的形态发育特征是：宽度变化幅度甚微，其长度从产孢细胞开始形成，至产孢前增长很为显著，至开始产孢后，长度增长逐渐缓慢，进入大量产孢期后，长度变化即趋于稳定。多芽产孢细胞形态发育特征是：产孢前其长度亦有明显的增长，但是进入产孢阶段后，随着产孢细胞上芽状突起数量的增加，长度仍不断增长，当发育到一定程度后，才趋于稳定。

Abstract: In most species the conidiogcnous cell is a phialide,a polyblastic cell occurs on certain species only.Both of them are the chief types of conidioge.nous cell in the genus.F usarium solani,F oxys porum and A.momliforme are phialides,while F.semitectumis polyblastic.All those types have been studied.The developmental mode of phialide is characterized by its stable shape and width after full growth and the length elongates continously,until it reaches most reproductive period.In polybiastic cell,the whole cell increases in size before sporogenous period.In sporogenous period,conidiogenous sites rise successively,and its length elongates continously.As it approaches to certain degree of size the polyblastic cell ceases its enlargement.
