Abstract: (312 Views) |
Gladiolus (Gladiolus grandiflorus L.) is one of the most important cut flowers in Iran and globally. Improving its morphological, biochemical, and post-harvest characteristics is crucial in the floriculture industry. For this purpose, the 'White Prosperity' cultivar was treated with gibberellic acid (GA3) as a priming agent and foliar spraying with salicylic acid (SA). The experimental design was a factorial arrangement in a randomized complete block design with four replications. The concentrations of GA3 were 0 and 150 mg L-1, and the concentrations of SA were 0, 50, 100, 150, and 200 mg L-1. The results showed that the combined use of priming with 150 mg L-1 of GA3 and spraying with 200 mg L-1 of SA positively affected protein and carbohydrate content, nitrogen and potassium absorption, the number of cormlets, and vase life. Increasing the concentration of SA enhanced these characteristics. Additionally, the results indicated that priming with GA3 alone or spraying with SA alone had a greater effect on total chlorophyll content, phosphorus absorption, inflorescence length, and diameter, and shoot weight compared to the combined treatments.
