title: [Plant hormones as bioregulators (author's transl)].
abstract: The discovery and general nature of phytohormones are described and the chemical nature and physiological modes of action presented of the five groups known at present: cytokinins, abscisins, gibberellins, auxins, and ethylene. These groups of substances interact in hormonal patterns that determine the measure of development of the different plant organs, also in relation to the environmental conditions. In their ability to control the growth and development of plants, both in the field and in in vitro culture, phytohormones form an interesting class of bioregulators.
