摘要

ABSTRACT: For the first time, hybrids of Spartina alterniflora × foliosa are reported to form mycorrhizal associations. This is important in light of the -invasion dynamics within San Francisco Bay—where Spartina hybrids are invading tidal habitats and causing functional changes in the ecosystem. Mycorrhizal associations can positively influence biomass production in invasive Spar-tina and may contribute to increased invasion success. Of the Spartina hybrids -investigated, 83% were mycorrhizal. During hybrid-ization, the ability to be mycorrhizal may be contributed by the native S. foliosa, also found to be -mycorrhizal, whereas the introduced S. alterniflora is non-mycorrhizal in its native habitat. Seedlings of Spartina hybrids inoculated with a commercial mycorrhizal mix showed greater above-ground growth and total biomass compared to control plants in the greenhouse. Mycorrhizal associations have the po-tential to influence the invasion trajectory of hybrid Spartina in San Francisco Bay, but additional research is needed.
