草生发网菌Stemonitis herbatica生活史的研究

Life cycle of the myxomycete Stemonitis herbatica

本文研究了草生发网菌Stemonitis herbatica从孢子萌发-原质团形成-幼子实体-成熟子实体的个体发育完整过程。结果表明,草生发网菌孢子萌发类型为孔出式;原质团类型为隐型,子实体形态建成前形成淡黄色的珊瑚状原质团,需足够的光照后才能形成子实体;子实体的形成过程通常在6–7h内完成。

The developmental process of Stemonitis herbatica from spore germination to plasmodium formation and sporulation was studied. It is obvious that the spore germinates by opening pore. The plasmodial type is aphanoplasmodium. It forms yellowish coralloid plasmodium before sporulation. Light was necessary for the fructification of S. herbatica. The sporulation process is irreversible which needs about 6-7h.
