Plant Growth Regulators and Morphogenesis in Cell and Tissue Culture of Forest Trees
Abstract
Plant growth regulators include naturally occurring plant hormones such as indoleacetie acid (IAA), gibberellins, zeatin, abscisic acid (ABA) and ethylene, etc., and also a number of synthetic chemicals that affect or control growth and development in plants. Each type of plant growth regulator has a wide range of physiological effects in different plants. These effects are determined by the kind of the growth regulator, its concentration, the presence or absence of other growth regulators, and by the genetic makeup and the physiological status of the target tissue. The same physiological response in different tissues even of the same plant may require different growth regulator(s) or different combinations of growth regulators. Synergism and quantitative interaction of two or more growth regulators are of common occurrence. Finally, a growth regulator that elicits a positive response in a given tissue at a given concentration may inhibit the same physiological response when used at higher concentrations.
