In vitro Propagation of Stevia rebaudina Plants Using Multiple Shoot Culture

Abstract

A multiple shoot culture was induced from nodal segments on MS medium containing half concentration of macroelements, 1% sucrose, and supplemented with NAA (0.01 mg/l). A bioreactor with hormone-free MS medium (300 ml) was inoculated with 1.5 g of the multiple shoot culture and cultivated for a month. The cultivating process of the multiple shoot culture in the bioreactor and the transfer into ex vitro conditions took about 8-9 weeks and produced approx. 600 new seedlings, that could be transferred from greenhouse to field conditions.
