How does gibberellin actually work
WebGibberellins are a group of hormones that help plants grow by stimulating cell division and elongation in the stem. Dwarf plant varieties have been shown to have very low levels of gibberellins. This is often due to a mutation in a gene involved in the synthesis of gibberellins. Under experimental conditions, treating these dwarf varieties with ...
