Revitalizing deteriorated sweet corn (Zea mays var. Saccharata Basin R) seeds through priming with ellagic acid, gibberellin, and potassium nitrate

Introduction:Poor seedling vigor is one of the major challenges in agriculture, as it reduces seed germination capacity and seedling establishment, directly impacting plant establishment and yield.The use of seed priming methods with chemicals and growth regulators c seedling vigor and improve biochemical traits and seed germination.In this study, the enhancement of sweet corn seedling vigor through priming with ellagic acid, gibberellin, and potassium nitrate was investiga under accelerated aging conditions.Materials and Methods: A factorial the Faculty of Agriculture at Yasouj University in 2024, factors.The first factor was accelerated seed aging at two levels (aged and non was seed priming at eight levels (no prime, hydropriming, ellagic acid at two concentrations (25 and 100 mg/l), gibberellin at two concentrations (50 and 150 m and 60 mg/l)).Biochemical traits and seed germination characteristics were measuredResults: The findings of this study revealed that seed deterioration significantly reduced germination characteristics, including germination percentage and rate, shoot length, root length (length and weight).Additionally, biochemical indices such as soluble sugar content and activity were negatively affected by agi malondialdehyde levels, and peroxidase enzyme activity, indicating heightened oxidative stress under aging conditions.Priming of deterioration seeds with ellagic acid, gibberellin, and p influenced germination characteristics and biochemical indices.Specifically, concentrations of 100 mg/ ellagic acid, 150 mg/l gibberellin, and 15 mg/ Conclusion: The results of this research demonstrated that pretreatment of deteriorat seeds with ellagic acid, gibberellin, and potassium nitrate significantly improved germination and biochemical indices.These treatments mitigated the negative effects of seed aging, enhancing seedling vigor and establishment.Therefore, these priming can be recommended as effective methods to improve the quality of Basin sweet corn seeds under various agricultural conditions.
