摘要：

To evaluate the potential effectiveness of plant growth regulators in improve seed germination and seedling vigor when applied during seed coating in sweet corn. 6-benzylaminopurine (6-BA), 1-naphthalene acetic acid (NAA), brassinolide and gibberellic acid (GA(3)) were added as seed coating agent, and seed germination, antioxidant capacity and seedling vigor of sweet corn were investigated. The results showed compared with the use of coating agent alone, plant growth regulators improved seed vigor and germination, especially GA(3) (200 and 250 mg L-1) and 6-BA (20 and 40 mg L-1) were added. Furthermore, 200 mg L-1 GA(3) treatment improved seed germination and antioxidant capacity and resulted in sweet corn seedlings with a better appearance. The results observed indicated plant growth regulators might be valuable agents in sweet corn seed coating.
