Role of Cytokinen and Auxin on the Multiplication Stage of Date Palm (Phoenix dactylifera L.) cv. Sukry

The effect of reducing the hormone concentration on bud and shoot multiplication of date palm (Phoenix dactylifera L.) cv. Sukry was investigated. The results indicated that low hormones promoted the formation of bud and shoot while high hormones inhibited the formation of shoots and buds. High hormones concentration resulted in abnormal growth and no sign of budding or shoot formation. The height of shoots was severely decreased by increasing the hormone concentration. Medium supplemented with 0.20 kinetin + 0.10 2ip + 0.10 BAP + 0.10 IAA + 0.10 NOA + 0.10 mg L-1NAA produced the highest fresh and dry weight.
