Improvement of the postharvest keeping quality of cut flowers and cuttings by application of water-soluble antioxidants.

ABSTRACT

Three water soluble antioxidants (morin, kaempferol and glutathione (GSH)) were applied as pulsing solutions for 20 h at 22 deg C to cut flowers of Godetia grandiflora [Clarkia grandiflora] (cv. Red) and rose (various cultivars including Frisco, Jaguar and Mercedes). Morin (0.1 mM) delayed leaf senescence and extended flower longevity in cut flowers of G. grandiflora. All 3 antioxidants improved the appearance and opening of the petals and extended vase life in cut rose flowers. The response, however, was cultivar dependent. For pelargonium (cv. Bailey) cuttings, a single dip in GSH (10 mM) or morin (1 mM) prior to storage in various packagings significantly delayed leaf yellowing, reduced decay and improved rooting ability.
