The rooting percentages increased significantly with time from planting for all IBA treatments. Significant interactions were noted between IBA concentrations and the time from planting to IBA concentrations and the cutting types, adapted between the cutting type and the time from planting to the sampling period. The number of roots per cutting were also influenced by the IBA level, 3000 ppm being ,the optimum level. The root dry weight was significantly influenced by the IBA treatments, the optimum IBA level being 3000 ppm, except in the case •of the terminal cutting which seemed to respond to higher IeveIs of IRA.
