兰科菌根菌对兰花种子萌发和原球茎生长起了重要作用,在成年阶段也扮演着重要角色(即使该兰花含有叶绿素)。为了解东南亚特有种五唇兰的菌根形态和菌根真菌的动态侵染过程,对不同生境下两种变异类型叶背绿色和叶背紫色的成年植株菌根分三个时间段采样并进行显微观察。结果表明,成年的五唇兰植株与菌根真菌有着密切关系,菌丝的侵染、定殖和消解程度随着生长发育变化而变化;在营养生长阶段和生殖生长阶段都发现菌丝结,这两个阶段的菌丝特征有所不同;而在休眠阶段的菌根中观察不到菌丝结;不同生境和不同变异类型的菌根结构无明显区别。研究结果为附生兰、地生兰和腐生兰的菌根结构的比较提供了参考。
Orchid mycorrhizal fungi on orchid seed germination and growth of protocorms played an important role in the adult stage also plays an important role (even if the orchid contains chlorophyll). In order to understand the mycorrhizal morphology and the dynamic infection of mycorrhizal fungi in Elaeocarpus sibirica, two different types of adult plant mycorrhizal fungi with different types of leaves were sampled and carried on three time periods Microscopic observation. The results showed that the adult plants were closely related to mycorrhizal fungi and mycelium infection, colonization and digestion with changes in growth and development; in the vegetative and reproductive growth stages were found mycelium knot, The mycelial characteristics of these two stages are different, but no mycelium is observed in the mycorrhizal stage of dormancy stage. There is no significant difference in mycorrhizal structure between different habitats and different types of variation. The results provide a reference for the comparison of the mycorrhizal structures of epiphyllous, terrestrial and saprophytic.
