Conservation Of South Florida Orchid Mycorrhizal Fungi, Ellen Garcia

FIU Electronic Theses and Dissertations

Starting in the late 1800’s orchids were heavily poached, leaving many species to reach critically low numbers. Coupled with habitat loss and urbanization many orchid populations were extirpated in southern Florida. Due to lack of endosperm, orchid seeds are reliant on specific mycorrhizal fungi to obtain nutrients to enable growth and development resulting in very low germination rates in nature. The obligate relationship on mycorrhizal fungi complicates orchid re-establishment. The research project aims are (1) to evaluate the correlation between phenotypic traits and optimal growing conditions in various micro-climate, and (2) to assess the range of mycorrhizal fungi community in …
