ABSTRACT
Purple corn (Zea mays L.) is a nutraceutically valuable crop due to its high content of antioxidant pigments. Salicylic acid (SA), a phytohormone, plays a key role in modulating physiological processes and enhancing stress tolerance. This study investigated the effects of varying SA concentrations (0.5, 1.5, and 5 mg) on growth and photosynthetic pigment production in purple corn seedlings grown in vitro on agar-agar. Measurements included root, stem, and leaf lengths, along with chlorophyll a, chlorophyll b, and carotenoid concentrations in methanolic leaf extracts. Treatments with 0.5 and 1.5 mg SA significantly promoted growth and pigment accumulation, particularly carotenoids, whereas the 5 mg dose substantially inhibited these parameters, indicating toxicity. These findings suggest that low doses of SA act as biostimulants, improving physiological health and photosynthetic efficiency, and hold promise as an agrotechnological approach for producing high-value nutraceutical seedlings.
