Effect of Age of Cuttings, Propagation Media, and Cutting Methods on Rooting of Stephanotis floribunda Brongn.

Abstract

The effects of cutting methods, cutting media, and age of cutting on rooting capacity of Stephanotis floribunda Brongn. were investigated to improve propagation efficiency. The effects of CO₂ enrichment and a new acclimatization technique for cutting were also tested.
1. Cuttings made from older shoots showed a higher rooting percentage than those made from younger ones.
2. Rockwool mats were found to be useful as a cutting medium for S. floribunda.
3. Cuttings with differentiated leaf buds showed higher rooting percentage than those without buds.
4. Rooting was stimulated by placing cuttings in a closed frame, especially when CO₂ concentration was high.
5. An acclimatization technique using a computer controlled fan was developed to decrease water stress during the acclimatization period.
