Plants Growth Hormones

Plant growth hormones play an important role in the growth and development of plants. These hormones are naturally produced by the plant, but can also be added to the plant through various means. Auxins are one of the most widely studied plant growth hormones, and play a vital role in regulating cell elongation and division, as well as other processes related to growth and development. Auxin helps to maintain the balance between cell production and cell death, allowing for the growth and development of the plant. Gibberellins are another type of growth hormone, which promote the germination of seeds and the growth of stems and leaves. Cytokinins are involved in cell division and leaf senescence, as well as root initiation and root growth. Ethylene is a gaseous hormone, which helps to regulate many aspects of plant growth, such as fruit ripening and abscission. Brassinosteroids are a group of growth hormones, which help to regulate leaf and stem growth, as well as flower and fruit development. Abscisic acid is involved in the process of dormancy and seed maturation, as well as the control of stomatal aperture.
