ISHS Acta Horticulturae 175: Symposium on Physiology of Productivity of Subtropical and Tropical Tree Fruits

CHEMICAL REGULATION OF PLANTS AND PLANT PROCESSES

Author:   J.A. Considine
Abstract:
Usage of chemicals (bioregulators) to regulate plant growth is growing at a rate faster than that of any other sector of the agricultural chemical industry. This growth is occurring because of an increase in the range of chemicals available for particular purposes, a wider awareness of potential usage, and development of a wider range of uses for particular chemicals.

Bioregulators, either naturally occurring or synthetic, have been shown to influence most if not all aspects of plant development, from seed germination to senescence and death. Exploration of the potential benefits that may be gained from the application of biologically active chemicals to tropical and sub-tropical fruit crops requires definition of management goals, judgement concerning whether these goals are attainable in the short or long term, and whether economically and socially desirable.

Three aspects of the use of bioregulators explored are:

  1. The compounds, classification and availability;
  2. The comparative developmental biology of tropical and subtropical species of fruits in relation to bioregulator usage; and
  3. The technology of usage of and an assessment of priorities for bioregulator research and development.
