The high percentage of living unrooted cutting the date of 20 Dec which 41,66%. All auxin treatments significantly increased on all vegetative and root growth characteristics and the best treatments was when applied auxin as a mixture 2000 ppm IBA + 2000 ppm NAA. The more effective interaction treatments between 2000 ppm IBA auxin and date of planting was 10 March which 93.33% of root percentage , followed by treatments of a mixture between 2000 ppm IBA + 2000 ppm NAA when planted at 10 March which 90% both interaction treatments significant increased as compared with interaction treatments.
