Plant hormones

Plant hormones are special chemicals produced by plants. These are the main internal factors that influence growth and development. Hormones are produced in parts of plants and are transported to other parts where they are highly effective. Given target tissue, given hormones may have different effects. Plant hormones play an essential role in controlling the growth and development of plants. Plant hormones are generally described as organic compounds that are synthesized in parts of plants and transferred to another part where low concentrations cause physiological responses.

The major classes of plant hormones - auxin, cytokinin, gibberellin, ethylene and abscisic acid - interact in a complicated way to produce mature growing plants. Unlike very specific animal hormones, plant hormones are not produced in established organs and there is no clear target area. They stimulate or suppress growth in response to environmental cues such as light, sunlight, temperature, hand touch and gravity, so that plants grow in a particular direction, produce flowers, or are suitable for their survival To effectively respond to the requirements of the environment by showing the response of the environment. At certain habitats

Plant hormones, also known as plant growth regulators, are synthesized in plant stems, leaves, flowers and roots cells. The hormone that controls the ability of the stem to grow into light is called auxin, which means "increase" in Greek. The main function of auxin is to stimulate the increase in the length of the cell near the apex and stem, thereby lengthening the plant. The more auxin is located in a particular region of the stem, the longer the cross section of the stem becomes. Plants that compete with sunlight or grow under dark conditions will form thin stems and dead leaves. They are usually tall and thin, and the stems are not colored enough. In severe cases, this physiological condition is called yellowing. Therefore, the darker the environment, the higher the plant height.
