Adventitious Root Formation in Tomato Hormone Mutants

摘要

The role of plant hormones during adventitious rooting has been studied for many years , yet their specific interaction(s) during rooting is still difficult to determine. It is accepted that auxin is the key hormone responsible for initiating adventitious roots. The other major hormones—gibberellin (GA), abscisic acid (ABA), and ethyl-ene- have been shown to promote, have no effect, or inhibit rooting depending on the species or rooting environment (Hartmann et al., 2002).
