Mycorrhizal fungi enter the velamen and exodermis through root hair, invade the cortical tissue by the exodermal passage cells and then form pelotons.

独花兰具有典型的兰科植物菌根构造，在光学显微镜下可以观察到菌根真菌从根毛进入根被和外皮层，通过通道细胞侵入到皮层薄壁组织，在皮层薄壁细胞内形成菌丝团。

Myconrrhizal fungus infected the cortical cells and formed pelotons in the cells, after it penetrated the exodermal passage cells through velamen cells. It is interesting that strain AR-18 also penetrated exodermis from the cortical cell next to it, where mycelium grew vigorously and infected inner cortical cell, even a few mycelium penetrated endodermis while there was no mycelium in the fibrovascular bundles.

真菌AR-15与金钗石斛一起培养时，真菌菌丝与根被细胞密切接触并侵入根被细胞，也可通过侵入根毛进入根被细胞，由根被继续侵入外皮层通道细胞，进一步向皮层细胞侵染；部分根被真菌危害，根部组织内有大量真菌孢子和菌丝。

Strain AR-15 penetrated the exodermal passage cells through the velamen cells or root hairs and further infected the cortical cells. There were a number of spores and hyphae in plant roots that was damaged by strain AR-15. Study on the ultrastructure of D. nobile root and its endomycorrhizal formationshowed that the wall of velamen cells of D. nobile root was thin, and there were waxylayers outside of velamen. Cells of exodermis were arranged tidily, having thick wallsand chloroplast.

金钗石斛根及其菌根的超微结构研究表明，金钗石斛根的根被细胞薄壁，在最外层根被细胞之外覆盖着蜡质层，外皮层细胞排列整齐，细胞壁厚，内含叶绿体，靠近外皮层的皮层细胞含叶绿体、线粒体，皮层细胞壁薄，细胞核明显，周围有叶绿体围绕，细胞膜附近有小泡结构。

Root hair was not present on the roots of this plant. Root of D.candidum possesses the typical root structure of orchids including velamen, exodermis,thick cortical tissue, endodermis, pericycle, vascular bundle and pith. Strain AR-18grew toward D.

真菌AR-18倾向于根生长，真菌在根周围形成了一个包围圈，并侵入根被细胞，由根被继续侵入外皮层通道细胞，进一步向皮层细胞侵染，在皮层细胞内形成菌丝结，从而形成内生菌根。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

金钗石斛菌根的根被细胞的细胞壁多处出现环形圈，外皮层细胞壁加厚，木质化，也有环形圈存在，皮层细胞细胞壁多角形明显，加厚，皮层细胞中存在被消化、失去结构的真菌菌丝，在菌丝周围有较多的线粒体、小泡，内皮层细胞的细胞壁呈现的典型的加厚及木质化环形圈，韧皮部筛管的筛板结构，绝大多数筛孔已为胼胝质所覆盖，仅个别筛孔中还存在连络索。
