Abstract: The seed germ inated rate, seed ling survival rate, seedling b iom ass and physiological characteristics of seedlings leaves
and rootswere investigated after Tsuga long ibracteata Cheng seeds sem inated in light intensity levels ( 100% , 50% , 25% , 10%
full sunlight) seedbeds for one grow ing season from 200 to 2006. The seed germ inated rate and seed lings survival rate w ere the
h ighest in the 50% fu ll sun ligh t environm ent. Full sunlight is not suitable for seed
