摘要
利用电子显微镜对蜜环菌隔膜发生及其结构分化进行研究。隔膜的形成首先是菌丝内壁横生,至中心时停止发育留下中心孔,孔侧的隔膜板膨大形成桶孔隔膜;同时孔口两侧出现孔帽,它是由内质网修饰而成;内质网、高尔基体、线粒体均与隔膜的发育有关。菌索髓部的薄壁菌丝处于休眠状态,这类菌丝和液体发酵时菌丝的隔膜均缺乏孔帽,但后者有较大的隔膜孔口,胞质环流明显,菌丝间融合频率高。此外,本文较系统阐述了蜜环菌隔膜结构变化与其功能的相关性。
The structure and development of septum in Armillaria mellea were studied under theelectronmicroscope.Hyphal septum was developed by inside wall of hyphae in cross direc-tion,leaving a small pore in the center.Then the septal plate arround the pore becameswollen,and formed a septal pore apparatus called dolipore septum,With subsequent devel-opment of endoplasmic reticulum septal pore caps appeared on each side of the pore.Or-ganelles,such as mitochondrium and Golgi body in hyphal cells were all related with the de-velopment of septa,Thin-walled narrow hyphae of the medualla in mature rhizomorph werein a state of dormancy,and their septa were similar to those of the hyphae growing from liq-uid fermentation.Both of them were short of septal pore caps,but the latter had larger septalpores,the protoplasm flow from cell to cell through the pore was visible,and fusion rate be-tween the hyphae was much higher.The relationship between the structural changes andfunctions of septa in A.mellea was also systematically discussed in this paper.
