Extended Abstract
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 can serve as an effective strategy to enhance 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 investigated under accelerated aging conditions.
Materials and Methods: This experiment was conducted in the Seed Technology Laboratory of the Faculty of Agriculture at Yasouj University in 2024, using a factorial design in a completely randomized design with two factors. The first factor was accelerated seed aging at two levels (aged and non-aged), and the second factor 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 mg/L), and potassium nitrate at two concentrations (15 and 60 mg/L)). Biochemical traits and seed germination characteristics were measured.
Results: The findings of this study revealed that seed deterioration significantly reduced germination characteristics, including germination percentage and rate, shoot length, root length and seedling vigor index (length and weight). Additionally, biochemical indices such as soluble sugar content and alpha-amylase enzyme activity were negatively affected by aging. On the other hand, seed deterioration increased proline content, malondialdehyde levels, and peroxidase enzyme activity, indicating heightened oxidative stress under aging conditions. Priming of deterioration seeds with ellagic acid, gibberellin, and potassium nitrate positively influenced germination characteristics and biochemical indices. Specifically, concentrations of 100 mg/L ellagic acid, 150 mg/L gibberellin, and 15 mg/L potassium nitrate were the most effective pretreatments.
Conclusion: The results of this research demonstrated that pretreatment of deterioration Basin sweet corn 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.

Highlights:
- Seed deterioration leads to an increase in biochemical indicators such as seed proline content, peroxidase enzyme activity, and seed malondialdehyde content.
- The vigor of Basin sweet corn seeds is improved through pretreatment with gibberellin and ellagic acid.
- The effect of priming before and after artificial deterioration on germination and seed vigor of sweet corn cultivar Basin was compared and investigated.
