EFFECT OF DIFFERENT AMINO ACIDS AT DIFFERENT CON-CENTRATIONS ON MULTIPLICATION AND ROOTING STAGE OF In vitro PROPAGATION OF STRAWBERRIES (Fragaria X Ananassa Duch cv. Chandler)
Abstract
The Present study was carried out for the purpose of enhancing strawberries (Fragaria X Ananassa Duch cv. Chandler) via In vitro regeneration. Since amino acid compounds provide a vital role in plant tissue culturing, this study was conducted for the purpose of identifying the optimum conditions and concentrations from three selected amino acid compounds. Tyrosine, Arginine, and Glutamine were added at different concentrations (0, 25 50 and 100 mg/L), separately and supplemented with standard MS nutrient culture medium. The results demonstrated that tyrosine at (25 mg/L) significantly promoted the shooting and rooting growths as well as the acclimatization stage (in vivo) development. Supplementation of the MS culture medium with arginine and/or glutamine at the assessed concentrations yielded results that were much better than the control culture nutrient medium for the induction of the shooting and rooting stages providing healthy plantlets.References
