The experimental results indicated that the seeds of kalopananx septemlobus had physiological dormancy because of unmature embryo and existence of inhibitory matter in the seed. Temperature-accelerated germination was a preferable and essential way to assure the germination. Seed dormancy could be overcome through accelerating germination.
