Abstract
During the 2021 and 2022 growing seasons, this study was conducted at the nursery of the Department of Flowers, Ornamental Plants, and Landscape Gardens, Faculty of Agriculture (El-Shatby), Alexandria University, Alexandria, Egypt. This study, aimed to test the effect of applying foliar sprays of gibberellic acid and benzyladenine in increasing the quality and performance of Tropaeolum majus L. plants. The Tropaeolum seedlings were planted individually in plastic pots 30 cm diameter. The plants were sprayed with gibberellic acid at the concentrations of 500, 1000 and 1500 mg/l and benzyladenine at the concentrations of 200, 250 and 300 mg/l and the interaction between them. The obtained results showed that spraying with gibberellic acid at 1000 mg/l and benzyladenine at 300 mg/l together significantly increased plant height, number of leaves per plant, leaves dry weight, leaves area, stem diameter, stem dry weight, number of branches per plant, root length and root dry weight. While, the obtained results showed that spraying with gibberellic acid at 1000 mg/l and benzyladenine at 250 mg/l together resulted in the highest chlorophyll content, carbohydrates content, nitrogen percentage in the leaves, phosphorus percentage in the leaves and potassium percentage in the leaves.
