Plant Tissue culture Project Mass propagation of dry forest tree species (woody plants) through micropropagation for restoration of degraded forests. Species which have high economic value and threatened species were selected to increase their density in dry forests to ensure their ecological restoration and increase biodiversity. Mass propagation of Stevia rebaudiana, a natural sweetener and a valuable medicinal plant through tissue culture techniques. This project is aimed at promoting the use of Stevia derivatives as an alternative to sugars in the food industry.
