The effect of new blend of (MS) medium on the initiation of primary buds and the fresh weight for date palm Phoenix dactylifera L. in vitro

الملخص

This study was carried out on the offshoots of Date palm (Phoenix dactylifera L.)  , the variety Zuhdi. The initiation of primary auxillary buds and the fresh weight increasing was studied for samples having 3 mm diameter which taken from the heart of three-years old offshoot grown in MS culture medium by using the following concentrations: 25%, 50%, 75%, 100% and 125% from the strength of the macronutrient elements, micronutrient elements and iron chelate of MS medium. Samples which grown at 50% of macronutrient showed best results when the concentrations of micronutrients and iron chelate are 50% and 100% respectively. The aim of the present study is finding  new blend of (MS) medium to increase the number of primary buds and the fresh weight.
