Abstract: In this study, the effects of the environmental factors such as light indensity and temperature, and seed quality to the seed germination of Phyllostachys edulis were investigated．Results showed that temperature was a main limiting factor affecting the seed germination of Phyllostachys edulis. The optimal germination temperature ranges of Phyllostachys edulis were between 20℃ and 30℃．Germination was stopped below 15℃ or over 35℃．The optimal temperature for seed germination of Phyllostachys edulis was 25℃. Alternate temperatures were helpful to gernination uniformity .Light was not a significant and essential factor for the germination，but high light intensity could inhibit seedling growth.Seed plumpness was a crucial factor for seed vigor, obviously influenced germination course, germination uniformity and seedling health.GA3 increased germination energy, index of germination and index of vigor obviously, accelerated germination course and seedling growth. The optimal concentration ranges of GA3 were between 100～200mg/L.
