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 | PLANT CELL BIOTECHNOLOGY AND MOLECULAR BIOLOGY

 This research was conducted at the University of Basrah Date Palm Research Center for the period from 25/1/2018 to 3/2/2019 AD in order to understand the impact of polyamine puterscine (put) and salicylic acid (SA) on the multiplication and elongation of vegetative buds and to summarise the results obtained:

1 -Put in addition. Important increases in the amount of vegetative buds and chlorophyll pigment and carotene concentration (21.23 buds, 0.98 and 0.079 mg.gm-1 fresh weight) were observed in the MS medium at a concentration of 150 mg.L-1 respectively, while the same concentration decreased from the percentage of deformed buds and phenols (15.55 percent and 30.86 mg.gm -1 fresh weight).

2- The SA extension. 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) is greater than the diameter of the buds and the leaf content of the chlorophyll, carotene and carbohydrate dye (20.16 percent and 15.19 mg.gm-1 fresh weight), respectively.

3- Association of the 150 mg L-1 Placed concentrations. 1 mg.L-1 SA, as well. The amount of deformed buds and phenols (13.33% and 26.23 mg.gm-1 dry weight) showed a substantial increase relative to the other chlorophyll and carotene interactions that were (7.25 and 0.113) mg.g-1 fresh weight, respectively, while the same interactions decreased.
