Knowra Plant growth regulator Plant growth regulator A natural or synthetic substance that changes plant growth or development, often by altering signaling between cells. The term includes plant hormones and substances applied to crops.
Auxin : A plant hormone that regulates cell elongation, root formation, and responses to light and gravity. Auxin signaling can be enhanced or disrupted to redirect growth and rooting.
Ethephon : A plant growth regulator that releases ethylene in plant tissues. It is used to promote fruit ripening, flowering, or fruit loosening, depending on the crop.
Plant hormone : A signaling molecule produced by plants that regulates growth, development, or environmental responses. Plant growth regulators include these naturally occurring signals and compounds that alter their effects.
Plant growth promoter : A substance that enhances one or more aspects of plant growth or development. Promoters are a functional subset of regulators, which may also inhibit growth.
Gibberellin : A class of plant hormones that promotes processes including stem elongation, seed germination, and flowering. Gibberellin treatments can stimulate elongation or overcome seed dormancy.
Chlormequat chloride : A plant growth regulator that inhibits gibberellin biosynthesis and limits stem elongation. It helps reduce lodging in cereal crops by shortening and strengthening stems.
Plant development : The changes in form and function through which a plant grows from a seed into a mature organism. Regulators can affect developmental transitions as well as the rate of growth.
Plant growth retardant : A substance that slows shoot elongation or otherwise restricts plant growth. Retardants are regulators chosen specifically to restrain growth.
Cytokinin : A class of plant hormones that promotes cell division and influences shoot growth and leaf aging. Cytokinins can shift growth toward shoot formation and delay senescence.
Paclobutrazol : A plant growth regulator that inhibits gibberellin biosynthesis and restricts shoot growth. It is used to control plant height and canopy growth.
