Abstract:Gibberellins (GAs) regulate diverse aspects of growth and development, but their role in root development and lateral root (LR) formation is poorly understood. In this study, GA3 was applied to soybean [Glycine max (L.) Merr] by seed soaking. The results showed that root length and root surface area were significantly inhibited in early stages after GA3 treatment. Microscopic examination showed that GA3 treatment changed the cortex thickness, the pericycle diameter, and cell size in main root. Interestingly, e… Show more
