The experiment was carried out in the laboratories of the Date Palm Research Center / University of Basrah, to test the effect of Vegeamino and Drin on the growth and development of callus and date palm plants of the Barhi variety invitro .

Activators were added with the same concentration of 0.5 ml.

L-1 in two separate experiments with four treatments of MS salts( ¼, ½, ¾, 1) in addition to the comparison treatment without any addition to the formation of nine treatments, and the results showed that the medium supplied with (Veg + ¾MS), showed superiority in the callus which significantly superiored all trial treatments to 1.083 g, followed by the comparison treatment (free from any addition), recording 0.903 g, which did not differ significantly from each of the treatments (Drin + ½MS, Drin + ¾Ms, Veg + ¼MS and Veg + ½MS) of 0.864, 0.836, 0.809 and 0.844 g, respectively, while the two treatments that contained a full concentration of MS salts were recorded with the lowest values of 0.569 g and 0.258 g compared to the comparison, the highest mean for Vegetative shoots was 4.03 shoots and without significant differences with the coefficients (Veg + ¼MS, Veg + ½MS Veg + ¾MS), which recorded 3.33, 3.23 and 2.83 shoots respectively, superior all Drin coefficients (Drin + ¼MS and Drin + ½MS and Drin + ¾ MS) without significant differences between them, treatment with full concentration of MS salt recorded 0.93 shoots as the lowest value.

The results also showed the superiority of the treatment of Vegeamino with MS salts in the leaf content of plant pigments , while the treatment of Drin with 1l 2 MS salts recorded the lest value of total soluble phenols in plant tissue and the treatment of Drin was recorded with the full concentration of MS salts the highest value of total soluble carbohydrates.
