“…The treatments applied were the following: IAA at four concentrations (0.5, 1, 2 and 3 mM) and an absolute control with deionized water, which were established based on the study by Vidyullatha and Topno (2022). The treatments were applied via the foliar route, a manual sprinkler was used, and the plants were sprayed to the point of dripping.…”

Indole-3-acetic acid (IAA) is the main auxin in plants and controls various physiological and biochemical processes such as cell elongation and division, tissue differentiation, responses to light and gravity, and response to biotic stress and abiotic. Therefore, the objective of the work was to evaluate the effect of foliar application of high concentrations of IAA (0.5, 1, 2, and 3 mM) plus a control (distilled water) on agronomic and metabolomic variables in melon seedlings. The results indicate that for agronomic variables, IAA at a concentration of 0.5 mM improved height by 20.98 %, compared to the control, and after 1 mM it began to decrease as IAA concentration increased. For the total fresh and dry biomass, it can be seen that the control and the 0.5 mM concentration were statistically equal, however, from 1 mM the biomass began to decrease as the IAA concentration increased. Regarding the biomolecules, an increase in chlorophylls (a, b and total), flavonoids, antioxidant capacity and proteins is observed as the IAA concentration rises. The 0.5, 1, and 2 mM IAA treatments increased the concentration of carotenoids by 11.76, 11.76 and 8.82 %, respectively, compared to the control, however, with the 3 mM concentration they began to decrease, but still exceeded the control. It is concluded that from the concentration of 1 mM of IAA the agronomic characteristics of the seedlings began to decrease, therefore, it is recommended that concentrations below 0.5 mM of IAA are used to be able to elucidate how lower concentrations work. Regarding the metabolomic variables, they increased as the IAA concentration.
