Hawaii yellow-eyed grass (Xyris complanata: Xyridaceae) inhabits infertile, acidic peat soil in the rainy tropical zone in Southeast Asia, and this monocot plant produces a large number of dormant seeds to make a large deposit to seed bank in the soil. Under laboratory conditions, surface-sterilized X. complanata seeds were rarely able to germinate on sterilized peat moss bed, while they required inoculation with either seed epiphytic or soil fungi to facilitate active seed germination. In the present study, three different genera of seed epiphytic fungi were isolated, and two common fungal genera, Fusarium sp. (strain R-1) and Penicillium sp. (strain Y-1), were found to promote the seed germination of this plant. In the sterile peat moss beds, the germination-stimulating fungi also showed growth-promoting effects on X. complanata seedlings growing. These results suggested that the seed germination-promoting fungi likely function as genuine partners for X. complanata in tropical, open peat lands.
