- 摘要:
- 以三年生对开蕨组培苗为试材，设置不同空气湿度（RH）(65±2)%、(75±2)%、(85±2)%处理，研究了不同空气湿度对对开蕨生长状况的影响。结果表明：空气湿度越大，植株生长越快，叶面积越大，新萌发叶数越多，叶片越平展光亮，但叶色浅淡；低空气湿度下叶面积较小，叶片褶皱，叶色深浓。综合得出在RH（75±2）%条件下对开蕨组培苗生长状况最佳，观赏效果最好。
- 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.
