HERNANDEZ SILVA, Eduardo  e  GARCIA-MARTINEZ, Ignacio. Brassinosteroids in agriculture. I. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.2, pp.441-450. ISSN 2007-0934.

Plant hormones, also acquaintances like fitohormonas, they are substances that they play a paper nail in the development in the plants, since they are able to regulate of prevailing way the physiological phenomena of the plants like the growth, and the development in response to the signs of ambient midway like light. The brassinosteroids are natural compounds that they find in small amounts in the organs of the plants, finding oneself in pollen principally, sheets, yolks, flowers and seeds, being characterized like compounds polihidroxifenólicos. The first one belonging to these compounds was isolated of Brassica napus's pollen and the explanation of his structure came true in the year 1979 for North American scientists. As of the present moment 45 members of the family of the brassinosteroids, which is why they constitute an ample family of compounds of powerful biological activity, proving that influence the germination, in the rizogénesis, in flowering, in the senescencia, in the abscission and in the processes of maturation, and the fact that they consider like the sixth group of fitohormonas is for this reason know themselves over. The recent discoveries of the physiological properties of the brassinosteroids allow regarding as natural substances themselves highly promissory and appropriate for his use in the protection of the plants and increase in the agricultural produce. Having in account it once before the objective of this work was exposed you are to deliver to know some of the principal physiological effects of the brassinosteroids and his analogous related with the defensive answer, the morphogenesis and the growth and development of the plants.

Palavras-chave : agriculture; brassinosteroids; the vegetable growth's regulators.
