The Impact of Auxin and Cytokinin on the Growth and Development of Selected Crops

With a very diverse structure and small molecules, phytohormones are regulators of plant growth development. Despite the fact that they synthesized by plants in quantities, highly active physiologically. According to their action, can be divided into two categories, as either activators development or inhibitors, with auxins cytokinins belonging former group. Auxins apical meristems shoots, but also young leaves, seeds, fruits. They stimulate elongation shoots initiate production adventitious lateral roots. Cytokinins, turn, formed root tips unripe fruits seeds. These hormones responsible for stimulating cytokinesis and, consequently, cell division. The aim this review paper is present progress research on effect selected crops, considering prospect using them growing methods.
