Impact of seed soak by ascorbic acid and foliar spray with boron in some morphological and physiological traits of wheat

This study included the investigation of the effect of wheat seeds (Abu Ghraib variety) priming at different concentrations of ascorbic acid and boron foliar nutrition on certain morphological and physiological characteristics of wheat plants. A field experiment executed in the city of Ramadi, Al-Jazeera region. The experiment included two factors: seed priming by ascorbic acid (vitamin C) at different concentrations (0, 10, 20, and 40 mg.l-1), represented by (P0, P1, P2, P3) and three concentrations of boron foliar spray at (0, 3, 5) mg.l-1 represented by (B0, B1, B2 ) were added to plants as Boric acid (H3BO3). The experiment was carried out according to the randomized complete block design (RCBD) with three replicates. The results showed that all ascorbic acid concentrations, boron foliar fertilization, and their interactions increased significantly with concentrations increasing in all studied characteristics. The highest significant differences were recorded at the concentrations of 40 mg.l-1 of ascorbic acid and 5 mg.l-1 of boron. (102.667cm ;14.000 branches. Plant-1; 68.55 cm2 and 5.227 mg.gm-1) for plant height, number of branches, leaf area, and total chlorophyll.
