In this article we will discuss about Indole-3-Acetic Acid (IAA) and Auxin in Plants. Natural and Synthetic Auxin: The main auxin in plants is indole-3-acetic acid (IAA Fig. 20-2). Additionally, several other naturraly occurring indole derivatives are reported to express auxin activity, including indole-3- ethanol, indole-3-acetaldehyde, and indole-3-acetonitrile. It may be noted that all these […]

In this article we will discuss about the transport of growth hormones in plants. Non-Hormonal Factors: Carbon dioxide has been known for a long time to stimulate plant growth. There are at least two CO2 responses which depend on the CO2 concentrations. One is the responses to low concentrations, e.g. 0.03% and the other to […]
