Developments in the use of growth regulators for the maintenance of post-harvest quality in cut flowers and potted plants.

Anionic silver thiosulphate complex (STS) is used commercially to improve cut flower quality in numerous species. However, the use of STS has become controversial on environmental and practical grounds and alternatives are sought. Aminooxyacetic acid (AOA) and alpha -aminoisobutyric acid (AIB) produced similar results to STS in delaying petal wilting in carnations. Preliminary experiments using combinations of low [unspecified] concentrations of AOA and AIB indicated an additive effect. AOA was less effective than STS in delaying petal abscission and both AOA and AIB were largely ineffective against bud drying in lilies. Gibberellins were found to be effective in delaying leaf yellowing in cut flowering shoots of Alstroemeria, Lilium and Euphorbia fulgens. AIA and AIB are being tested for the prevention of leaf yellowing in pot plants. It is suggested that breeding for better postharvest quality may result in cultivars which do not require these chemical treatments, and genetic transformation may be used to produce commercial cultivars in which ethylene production is inhibited.
