One possibility how to increase the sweetener content in leaves is in application of growth regulators of different micro- and macroelements and growth hormones composition by foliar spraying. For micropropagation in vitro nodal segments of 6 weeks old seedlings cultivated on MS medium with half macroelements content and in the presence of growth hormone of auxine character (NAA) in concentration of 0.01 ppm were used. As a most effective preparation increasing concentration of stevioside in leaves proved to be Humiforte in combination with Aminol.
