Abstract:: Taking 3-year-old Phyllitis japonica as material，different air humidity of (65±2)%，（75±2）%，（85±2）% were set，growth status of tissue culture seedlings of Phyllitis japonica were studied under different air humidity.The results showed that with the increasing of air humidity，the plant grew faster，and the leaf area became larger，the more of new-fledged leaves germinated.New leaves growing in high air humidity their shape would be more flat and bright，but color was light.In low air humidity the leaves were small，fold，and dark color. Therefore，the tissue culture seedlings of P.japonica in air humidity of （75±2）% condition grew the best and had highest ornamental effect.
