Exogenous Gibberellic Acid and the Cytokinin Isopentenyladenine Retardants of Senescence in Romaine Lettuce1

Year: 1975

Type: article

Abstract: A single preharvest spray of gibberellic acid (GA 3 ), alone or with the cytokinin, isopentenyladenine (IPA), retarded leaf yellowing, and, to a lesser extent, leaf rot of romaine lettuce ( Lactuca sativa L. ‘Hazera Yellow’). The most effective spray was 10 ppm GA 3 plus 0.1 ppm IPA. Effects of 1 ppm GA 3 together with 0.1 ppm IPA were similar to those of 25 ppm GA 3 and were always superior to the controls (water-sprayed). Lettuce sprayed by the hormones and packed in polyethylene (PE) liners remained green and sound longer than that either sprayed or packaged.
