After inoculation of young leaves of date palm offshoot required about six months to complete the morphogenesis process. Fourteen weeks were required for embryogenic callus formation under continuous dark condition and nine weeks for shoot initiation (under 16/8 h light/dark). The highest number of explants (80%) produced callus in modified MS containing 5 mg/l 2,4-D + 2 mg/l 2ip. Sixty per cent of explants produced callus in the modified medium containing 5 mg/l 2,4-D + 5 mg/l NAA. while only 50 per cent of the explants formed callus in the same medium when supplemented with only 5 mg/l 2,4-D. The induced calli were transferred to modified MS for shoot proliferation. A combination of two cytokines showed better performance than single ones in shoot induction. The highest percentage (70) of shoot developed in modified MS containing 2 mg/l BAP + 1 mg/l Kn. Forty per cent shoot induction was found in the same medium supplemented with 2 mg/l of BAP. Thirty per cent shoot formed in MS containing 1 mg/l of Kn. The shoots were subcultured at three- four week intervals throughout culture duration. D. O.

Plant tissue culture is becoming an important technique for the massive propagation of date palm and the available source lead to the success of this process. The mature female inflorescence is a novel and available source for in vitro propagation of date palm, nowadays become needed at the large scale to usage of organic nature materials in agriculture practice which are rich in plant growth regulators as well as micro elements. This study describes in vitro plant regeneration from mature female inflorescence explants of evaluating date palm (Phoenix dactylifera L.) by using the methanol extract of Moringa oleifera leaves which has great potential to be used as a natural source of nutraceutical in micropropagation. Mature inflorescences explants were cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of an extract of  Moringa leaves with or without add TDZ at 0.2 and 0.6 BA mg/l. Indoles, phenols,  proteins,  amino acids, and carbohydrates were determined. The addition of different concentrations of an extract of Moringa oleifera leaves with TDZ at 0.2 and 0.6 BA mg/l gave the highest significant average percentage of callus formation, friable callus, germination of embryos and numbers of embryos comparing with other treatments. Also, given the highest significant values of free amino acids and carbohydrates were noted in callus and embryo germination stage.
