摘要：
Three kinds of the growth stimulatory substances for vesicular-arbuscular mycorrhizal (VAM) fungi were isolated from the 25% methyl alcohol (MeOH) eluates of Bahia grass roots fractionated by flash chromatography. One of them was identified as eupalitin (3,5-dihydroxy-6,7-dimethoxy-4′-hydroxy flavone). At 10 ppm, this compound significantly stimulated the in vitro hyphal growth of a VAM fungus, Gigaspora ramisporophora Spain. The others were not identified. These results suggest that the flavonoids such as eupalitin, and the unidentified compounds may act as signal molecules in VAM symbiosis.
