Throughout this investigation, the internodes growth of soybean will be measured depending on the wavelength of the UV-B radiation, and the number of hours in which the plants are exposed to it. This is a very important subject, since the soybean is one of the most used legumes worldwide. The fact that UV rays affect its growth, it’s a concern for the mayor agricultural producers of this seed. Agriculture as a whole has a major impact on the world’s economy. However, the soybean makes a large difference for our country's exports. This is the most important reason for the investigation of the effects of the UV-B radiation in the internodes growth of soybean.

Meristematic cells give rise to various organs of the plant and keep the plant growing.
Phytohormones, also called plant hormones are substances produced by plant cells in strategic locations in the plant and these plant hormones are able to regulate predominantly physiological phenomena of plants. Phytohormones are produced in small quantities in plant tissue, unlike animal hormones, they are synthesized in glands. They can action on the fabric itself in which they are generated or at long distances, by transport through the phloem and xylem vessels.
Plant hormones control a large number of events, including the growth of plants, together with their roots, leaf fall, flowering, fruit formation and germination. Hormones are vital to plant growth, and, lacking them, plants would be mostly a mass of undifferentiated cells. So they are also known as growth factors or growth hormones. A hormone involved in several processes, and in the same way, every process is regulated by the action of several …show more content…

They also promote the production of other hormones and in conjunction with cytokinins, they control the growth of stems, roots, and fruits, and convert stems into flowers. Auxins were the first class of growth regulators discovered. They affect cell elongation by altering cell wall plasticity. They stimulate cambium, a subtype of meristem cells, to divide and in stems cause secondary xylem to differentiate. Auxins act to inhibit the growth of buds lower down the stems (apical dominance), and also to promote lateral and adventitious root development and
