How does gibberellin actually work
WebApr 5, 2024 · Gibberellins (GAs) are hormones that are produced by plants and which are responsible for developmental processes, containing stem elongation, germination, seed dormancy, flowering, flower growth, and leaf and fruit senescence. Gibberellins are one of the longest classes of plant hormones. WebGibberellic acid is a plant hormone that helps with the germination of seeds, the growth of stems and leaves, and the development of flowers. It occurs naturally in gibberellin, which is produced by fungi in the genus Gibberella. This hormone was first isolated in 1896 from an extract of G. fujikuroi, which causes bakanae disease in rice plants.
