Abstract: Cytokinins are plant hormones that plants produce naturally and regulate plant growth including cell division and leaf senescence. Many chemical compounds have been synthesized and tested for cytokinin activity. Analysis of these compounds provides insight into the structural requirements for activity. Nearly all compounds active as cytokinins are N6- substituted aminopurines, such as benzyladenoe (BA). The beneficial effects of applied benzyladenine appear to be on account of formation of -SH compound and its cytokinin like activities and thus increased plant growth parameters viz., plant height, number of branches and dry matter accumulation. An application of benzyladenine increased the yield. Significant increase in seed yield of oilseed could be ascribed to cumulative effect of yield components viz., number of fruit, number of seeds and test weight which increased seed yield and ultimately led to greater seed production per unit area. Benzyladenine application significantly improved the quality of oilseed crops assessed as protein and oil content. Cytokinin (BA) may stimulate protein synthesis by stimulating the recruitment of previously untranslated mRNA in to polysomes.
