Steviol glycosides contained in Stevia leaves have considerable potential uses for the natural sweetener industry due to it’s antidiabetic properties, hence a large number of plant source is required to supply the industry. To overcome the hindrances in the propagation of Stevia plants using in vivo methods, an alternative technique of propagation using in vitro methods is needed. The micropropagation method with the RITA® (Recipient for Automated Temporary Immersion System) is used in the production of a large amount of stevia biomass in approximately a short period. The forming of flowers is one of the limiting factors interfering with the metabolite production, as the content of steviol glycoside will decrease after plant flowering dramatically. This mechanism happened because steviol glycoside synthesis and flowering process share the same precursor. However, this interfering factor could be inhibited by using a high-red LED induction to delay the flowering stage, which may contribute to higher biomass and glycoside concentrations through greater system productivity.
