猴头菌担孢子形成的扫描电镜观察

Scanning Electron Microscope Observation of Hericium erinaceus Basidiospore Development

对猴头菌担子及担孢子形成过程进行扫描电子显微镜观察,结果表明:随着猴头菌子实体的形成与发育,顶细胞内部核配和减数分裂的同时,担子和担孢子形成时外部形态发生一系列变化.据此可基本归纳为四个阶段:即担子分化期、担子膨大期、担孢子形成期、担子和担孢子成熟期.这四个阶段在尚未发育完全的菌刺的同一区段内可交迭并存.随着菌刺的成熟,从其基部向尖端,担子和担孢子也逐渐发育成熟.

A series of morphological changes of Hericium erinaceus basidium and basidiospore development was observed with scanning electron microscope at the time of nuclear association and meiosis during the development of fruit-body. According to these changes, their development process was divided into four stages: basidium differentiation stage, basidium swell stage, basidiospore initiation stage and basidium and basidiospore maturing stage. On an immature acicula, these four stages might appear at the same zone simultaneously. But with the maturing of the acicula, basidia and basidiospores were also gradually developed into maturation from the basal part to the tip of an acicula.
