Gibberellin and Seed Germination

Vishal Jain


Plants undergo several developmental processes throughout their life-cycle. Several plant hormones participate in these growth and developmental processes. Plant hormones are chemical signals that are produced by cells in one area such as leaves, stems or root, and transported to a different area of the plant, where it generates a specific response. In this way, hormones co-ordinate different parts of the plant and regulate various physiological activities. Five major plant hormones are known: auxin, ethylene, cytokinin, abscisic acid and gibberellin. Though required in very small quantities, all of these play countless important functions in plants. This review describes the importance of gibberellin hormone in plants with main emphasis on its role in seed germination.
