In vitro flowering of orchids

Abstract

Flowering is the most elusive and fascinating of all plant developmental processes. The ability to induce flowering in vitro in orchids would reduce the relatively long juvenile phase and provide deeper insight into the physiological, genetic and molecular aspects of flowering. This review synthesizes all available studies that have been conducted on in vitro flowering of orchids with the objective of providing valuable clues as to the mechanism(s) that is possibly taking place.
