We at ULPL under take any specific need of plant-tissue culture in-vitro cultivation of plant cell or tissue under aseptic and controlled environment conditions, in liquid or on semisolid well defined nutrient medium for the production of primary and secondary metabolites or to regenerate plant. In other words it is an experimental technique through which a mass of cells (callus) is produced from an explant tissue. The callus produced through this process can be utilized directly to regenerate palntlets or to extract or manipulate some primary and secondary metabolites.
