    The effects of three temperature levels (150, 21°, and 33 o C) in combination with four soil-water regimes (moist-drained, surface-saturated, flooded-stagnant, and floodedaerated) on the germination of seeds of swamp tupelo (Nyssa sylvatica var. biflora (Walt.) Sarg.) were investigated. Germination was rapid in the moist -drained regime at temperatures of 21 o and above. No germination occurred in potted soil where water levels were at or above the soil surface, regardless of temperature or whether the water was aerated. However, seeds germinated under water in the absence of soil, and aeration and partial removal of the seedcoat
    enhanced germination and early growth of the radicle. Seeds that had been submerged in flooded soil for up to 5 weeks germinated when placed in moist sand, but the germination response of such seeds was substantially reduced at 33° C.
