The Effect of Thidiazuron on Callus and in vitro Shoots Development of Date Palm (Phoenix dactylifera L.) cv. Barhee

Abstract

Date palm (Phoenix dactylifera L.) is one of the most important fruit trees spread in southern Iraq, but because of many circumstances decreased their numbers significantly, the propagation of date palm by tissue culture was the best solution for re-preparation of the problem as it was previously, because propagation is accelerated. Summarizes the working paper in an attempt to find the optimal concentration of thidiazuran (TDZ) (0.0 , 0.5 and 1.0) mgl-1, in production of callus and regeneration of shoots, at different times of initial and callus culturing in medium budding. The results showed that the concentration of (0.5) mgl-1 was optimal in all traits under study.
