Synthetic vs Natural Growth promoting hormones

The nursery industry has been using synthetic auxins such as indole-3-butyric acid (IBA) and 1-naphthaleneacetic acid (NAA) to assist in the development of adventitious roots on plant cuttings for many decades. This Nursery Paper provides an overview of research by Masters student Apriwi Zulfitri to determine if inoculation of plant cuttings with indole-3-acetic acid (IAA)-producing plant growth promoting rhizobacteria (PGPR) may be a cost-effective alternative to using synthetic auxins in the propagation of ornamental plants.
