Hormones in Tissue Culture and Micropropagation

Abstract

Identification and characterization of the role of hormones in plant growth regulation has been closely linked to studies on development in vitro. Aseptic culture techniques, and the use of hormones in nutrient media that usually goes with it, are now more widely used than ever in basic and applied research (39). Several categories of hormone are recognized, but search for new growth regulatory molecules continues and inevitably new categories will be erected. In all this, study of the identity, effects and mechanism of action of hormones will rely heavily on in vitro techniques.
