Abstract
Senescence in perishable plant tissue is inhibited by the application thereto of an effective amount of a compound of the formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are each selected from the group consisting of hydrogen, --OH or --OR.sub.7, provided that at least one of R.sub.1 to R.sub.5 is a hydroxyl group, R.sub.6 is selected from the group consisting of --OH, --OR.sub.8 and --NHR.sub.9, R.sub.7 is a substituent group, R.sub.8 is the residue of an ester-forming compound and R.sub.9 is the residue of an amide-forming compound. The compound may be prepared synthetically and, in some cases, can be isolated from natural sources, for example, the glucose ester of ferulic acid may be isolated from carnation petals.
