Effect of Exogenous Application of Salicylic Acid

The effect of salicylic acid on antirrhinum growth, development, and post-harvest life was investigated in a study during the years 2020-2021. The research was carried out at the Institute of Horticultural Sciences, University of Agriculture Faisalabad. The study used a Randomized Complete Block Design with three replications and four different salicylic acid concentrations: 100 mg L-1, 300 mg L-1, 600 mg L-1, and 900 mg L-1. There are different plant morphological and physiochemical attributes are studied and collected data using statistix 8.1 software was statistically evaluated. The study found that using 600 mg L-1 salicylic acid concentration increased plant height (91.33 cm) while lowest with control (74.45 cm), plant fresh weight (43.67 g), and flower quality (9.17). The salicylic acid at 900 mg L-1 concentration increased the number of leaves (59.33), flower stalk length (6.17 cm), and total number of florets (35.17), while using 100 mg L-1 salicylic acid concentration increased flower opening percentage (57.02 percent), leaf relative weight (43.67 g) and vase life (8.75 days) while in control (6.67 days).
