Seedling culture ofKalopanax septemlobus

Experiments on temperature-accelerated germination, seeding quantity, and optimum density of seedling were made forKalopanax septemlobus. The experimental results indicated that the seeds ofkalopananx 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. Firstly, warm treatment should be done, morphological maturity occurred, then, followed by lower temperature treatment, reaching physiological maturity. Seeding quantity, optimum density and the relations between density of seedlings and yield were studied. Responsible Editor: Chai Ruihai
