摘要

The rooting potential of wild caper plant (Capparis spinosa var. Pariflora) leafy and leafless cuttings of different lengths (10, 15 and 20 cm) and cutting source [from growing season (softwood) and one year old stems (semi-hardwood)] was determined under different conditions. Bases of cuttings were treated with indole-3-butyric acid (IBA) at different concentrations and planted in an enclosed mist propagation system. Softwood cuttings did not root while only a small percentage (16.1%) of semi-hardwood cuttings rooted. IBA induced rooting poorly in all cuttings but, irrespective of the concentration, it improved the rooting capacity relative to the control. The highest rooting percentage (16.1%) was obtained when leafy 15 cm semi-hardwood cuttings were treated with 2 g l~(-1) IBA. Possible reasons for poor rooting ability of this species by IBA are discussed.
