Impact of Ascorbic Acid Spraying on Some Vegetative Development Traits of Safflower Genotypes (Carthamus tinctorius L.)
Year: 2025
Type: conference-paper
Abstract: This applied research was conducted to study the influence of different concentrations of ascorbic acid on the vegetative part traits of safflower genotypes. Planting was took place on a farmer’s land in Ramadi town for winter season 2023-2024. A split-plot arrangement was used to implement this experiment in three replications, according to a randomized complete block design(RCBD). The main plot contained ascorbic acid concentrations, which are (0, 50, 100) mg L−1, as for the Subplot includes three genotypes of safflower, are (MAJ-2, MAJ-7, MAJ-36). Which are symbolized as G1, G2, and G3, respectively. The results showed : The MAJ - 2 (G1) genotype excelled in giving the greatest mean for height of: plant (148.52 cm), branches number (14.93 branches plant−1), leaf chlorophyll content (57.25 spad), and plant dry weight (316.67 g). As for the genotype MAJ - 36 (G3), It required the least time to get the producing flowers phase, amounting to (70.22 days). The level of 100 mg L-1 of ascorbic acid give the lowest mean for the interval between put seed in the ground and the onset of flowering, is 72.22 days. It was also distinguished by providing the highest average for height of plant 153.33 cm, and branches number, 16.30 branches plant−1.The genotype (G1) exhibited a significant connection with the concentration of 100 mg L-1 in: height of plant, plant branchsand chlorophyll content in leaves.
