Abstract
This study was conducted to determine the effect of spraying different concentrations of chelated iron 0, 30, 60 mg L-1, Prosol 0, 50, 100 mg L-1 and amino acid proline 0, 100 and 200 mg L-1 in the vegetative, root and chemical characteristics of pomegranate seedlings cv. Salimi. Results indicated that spraying with chelated iron F2 at a concentration of 60 mg L-1 had a significant effect on the branches length 74.148 cm, shoot dry weight of 54.513 g plant-1, root diameter 7.618 mm, roots number 6.185, leaves content of nitrogen, phosphorous and boron reached (2.079 %، 0.358 %، 77.594 mg.kg-1dry weight)، respectively. As for the nutrient solution Prosol, treatment S2 with concentration 100 mg L-1 showed a markable increase in the branches length, shoot dry weight, root diameter and roots number with values of 71.185 cm, 54.135 g plant-1, 7.003 mm, and 6.074 root seedling-1 respectively. As for proline the results confirmed the superiority of the treatment P2 with concentration 200 mg L-1 in increasing the bramches length 68.148 cm, shoot dry weight 53.609 g plant-1, root diameter 6.791 mm, roots number 6.296, in addition to nitrogen and phosphorous and boron in the leaves، while the binary interaction between chelated iron and the nutrient solution prosol (F×S) and the interaction between chelated iron and the amino acid proline (F×P), as well as the interaction between the nutrient solution prosol and the amino acid proline (S×P) were significantly superior in most of the traits. studied، and for the triple interaction between the study factors (F×S×P)، the treatment F2S2P2 had a significant effect on the length of branches 86.666 cm, root diameter 8.666 mm, roots number 8000 root seedling-1 nitrogen، phosphorous and boron in leaves 2.250%, 0.403%, 84.266mg.mk-1dry weight respectively.
