What are the six major plant hormones?
The most obvious effect of auxin IAA (a synthetic representative is α-naphthaleneacetic acid) on plants is to promote cell growth, followed by strong nutrient transport. Gibberellin GA3 (representative of 920) is the most prominent role is to stimulate the elongation of the stem, apparently increase the height of the plant without changing the number of stems, preserved fruit. Cytokinin CTK (a synthetic representative is kinetin) induces cell division, regulates its differentiation, promotes sprouting of buds, increases flowering rate, promotes fruit development, and delays plant senescence. Abscisic acid ABA (currently no synthetic representative substance) inhibits plant growth. Ethylene ETH (synthetic representative is ethephon) promotes maturation. Brassinolide BR (natural product represents Yingtianfeng) combines the combined efficacy of gibberellins, cytokinins, and auxin, multiple regulation, period of use, and crop diversity.
