THE EFFECT OF PUTERSCINE AND SAL SALIC ACID AND THEIR INTERACTION ON THE MULTIPLICATION OF VEGETATIVE BUDS AND THEIR CHARACTERISTICS FOR DATE PALM CULTIVARS AL-BARHI In vitro

This study was conducted at the Date Palm Research Center University of Basrah for the period from 25/1/2018 to 3/2/2019 AD, with the aim of knowing the effect of polyamine puterscine (put) and salicylic acid (SA) on the multiplication and elongation of vegetative buds and the results obtained can be summarized come:

1 - Addition of Put. to MS medium at a concentration of 150 mg.L-1 recorded significant increase in number of vegetative buds and Chlorophyll pigment and Carotene concentration (21.23 buds, 0.98 and 0.079 mg.gm-1 fresh weight) respectively, while the same concentration decreased from The percentage of deformed buds and phenols was (15.55% and 30.86 mg.gm -1 fresh weight).

2- The addition of SA. in the concentration of 1 mg.L-1 exceeded the diameter of the buds and the leaf content of the chlorophyll, carotene and carbohydrate dye (0.65 mm, 6.66 and 0.099 mg.gm-1 Fresh weight and 23.05 mg.gm-1 Dry weight), respectively, in reducing the same concentration of deformed buds and phenols (20.16% and 15.19 mg.gm-1 fresh weight), respectively.

3- The interaction of the concentrations 150 mg L-1 Put. and 1 mg.L-1 SA. showed a significant increase than the other interactions of chlorophyll and carotene which were (7.25 and 0.113) mg.g-1 fresh weight respectively, while the same interactions decreased the Percentage of deformed buds and phenols (13.33% and 26.23 mg.gm-1 dry weight ) respectively.
