Research progress of saprophytic orchids
摘要
Abstract
Saprophytic orchids also called fully mycoheterotrophic orchids, without leaves and chlorophyll, losing the pho-tosynthetic ability to create organic matter and depending entirely on mycorrhizal fungi for their supply of nutrition. In recent years, their unconventional mode of life have attracted attention of biologists in the field of physiological ecology and evolu-tionary . Based on collecting the Flora of China and the newest related literatures, there are 81 species in 23 genera of sapro-phytic orchids in China. Species fall mainly within genera such as Gastrodia (24 species), Neottia(8 species), Aphyllorchis (6 species) and Galeola(5 species). The mycorrhizal fungi of saprophytic orchids have more differences compared with oth-er orchids bacause of their particular nutritional requirements. Numerous academic studies have shown that there are two major groups of mycorrhizal fungi of saprophytic orchids. One is ectomycorrhizal fungi, the other is non-rhizoctonia SAP fun-gi. In addition, the specificity between saprophytic orchids and their mycorrhizal fungi were discussed, advances on nutri-tional source and evolution of saprophytic orchids were summarized, the problems in current research were mentioned, as well as the future research were proposed. Overall, the review provides a reference for resources conservation and further study of saprophytic orchids.关键词
