Plant Growth Regulators

Plant growth regulators PGRs have been an important component in agricultural production even prior to the identification of plant hormones. For example, in order to synchronize flowering in mango or in pineapple, fires were lit adjacent to fields 43 in which these crops were grown. The ethylene generated as a result of incomplete combustion stimulated flowering, although this explanation was not understood at the time. Heat treatment of lemons was also used to stimulate ripening and degreening 12 , the ethylene generated from inefficient heating units again promoting the ripening process. PGRs are now used on over one million hectares worldwide on a diversity of crops each year Most of these applications are confined to high-value horticultural commodities rather than field crops, although there are several significant exceptions, such as chlormequat chloride 2-chloroethyltrimethyl-ammonium chloride for lodging control in wheat, glyphosine N,N-bis phosphonomethyl glycine for increased sugarcane yield, and DEF S,S,S-tributylphosphorotrithioate for cotton defoliation.
