Emergence and survivorship of Quercus serrata seedlings were followed periodically on the forest floors with intact and experimental treatments, for three years (1988-1990), in a mature Q. serrata stand with developed understory of evergreen shrubs (e.g. Eurya japonica) near urban areas. Treatments were with and without litter layer after the understory cleared. Relative illuminance on the floor was increased by clearing the understory. The greatest number of new seedlings emerged on the floor without litter layer and understory. Seedling emergence on intact floor was delayed about one month. Every early emerged seedlings had a lower initial mortality, and the survivorships were best compared with other later emerged ones. Survival rate of current seedlings was significantly the lowest in the intact floor. Survival rate of one-year seedlings was the highest on the floor with litter layer and without understory, and was the lowest on the intact floor. No seedlings survived on the intact floor at the time after three years following their emergence. More branched seedlings occurred on the floor without understory. Survival rate of branched seedlings was significantly higher than that of unbranched ones. It was concluded that Q. serrata seedlings could not establish on the floor with developed understory, but the understory clearing provided favorable conditions for their survival in the Q. serrata stand.
