There are five groups of plant-growth-regulating compounds auxin, gibberellin, cytokinin, ethylene, and abscisic acid. For the most part, each group contains both naturally occurring hormones and synthetic substances. [Pg.236]

C10H9N5O, Mr 215.21, mp. 267°C. K. belongs to the cytokinin group and is a derivative of adenine it occurs in various higher plants and yeasts and acts as a cell division factor. Like the closely related zeatin, K. is still active at million-fold dilutions and is thus considered to be a plant hormone. K. is isolated from autoclaved, aqueous slurries of deoxyribonucleic acids and is sometimes considered to be an artefact. K. is used as a plant growth regulator and also for inducing callus formation in plant cell cultures, etc.. ... [Pg.339]

Fig. 11.2. Chemical structures of plant growth regulator compounds out of the five main PGR categories auxins (lAA, 2,4-D), ethylene (ethephon), cytokinin (kinetin, benzyladenin), growth inhibitors (ABA), and gibberellins (GA3).

In order to improve yields and productivities of secondary metabolites in plant cell culture s it is essential the selection of the most elEcient plant growth regulators (auxins, cytokinins, gibberellic acid and abscicic acid) and the relationship between diem [74, 75]. [Pg.140]
