摘要

台湾杜鹃花(rhododendron formosanum Hemsl.)是美洲属植物在台湾的特有种。从台湾杜鹃花根中分离到一株Rf28真菌，根据其形态特征鉴定为一种内生种。DNA序列分析进一步支持了这一鉴定。本种是台湾真菌区系的新属种。在菌根合成过程中，接种rf28的台湾杜鹃幼苗生长旺盛，根系超微结构检查显示，在皮质细胞中出现菌丝复合体和菌丝线圈。结果表明，台湾杜鹃花在离体培养基中可以与phalocephala spp形成菌根。

Axenic Synthesis of Ericoid Mycorrhiza in Rhododendron formosanum with Phialocephala Species

Formosan rhododendron (Rhododendron formosanum Hemsl.) is an endemic species of Erica-les in Taiwan. The Rf28 fungal strain was isolated from the roots of Formosan rhododendron and identified as an endophytic species of Phialocephala based on its morphological characteristics. This identification was further supported by a DNA sequence analysis. This species is a new addition to the fungal flora of Taiwan. In ericoid-mycorrhizal synthesis, Rf28-inoculated Formosan rhododendron seedlings exhibited vigorous growth, and an examination of the root ultrastructure revealed the occurrence of hyphal complexes and hyphal coils in cortical cells. These results demonstrated that Formosan rhododendron can form ericoid mycorrhiza in vitro with Phialocephala spp.

期刊介绍： The Taiwan Journal of Forest Science is an academic publication that welcomes contributions from around the world. The journal covers all aspects of forest research, both basic and applied, including Forest Biology and Ecology (tree breeding, silviculture, soils, etc.), Forest Management (watershed management, forest pests and diseases, forest fire, wildlife, recreation, etc.), Biotechnology, and Wood Science. Manuscripts acceptable to the journal include (1) research papers, (2) research notes, (3) review articles, and (4) monographs. A research note differs from a research paper in its scope which is less-comprehensive, yet it contains important information. In other words, a research note offers an innovative perspective or new discovery which is worthy of early disclosure.
