Post-harvest immersion of lime (cvs 'Persian' and ‘West Indian') in solutions of N6-benzyladenine increased chlorophyll retention during subsequent storage at several combinations of temperature and relative humidity. Cv. 'Persian' stored at high temperature and low relative humidity was exceptional in that any effect of treatment was obscured by dehydration of the skin which occurred before any marked change in colour. Post-harvest immersion of 'West Indian' limes in solutions of gibberellic acid increased chlorophyll retention during subsequent storage under the same conditions for which N6-benzyladenine was effective. Waxing reduced the rate of loss in weight of fruit of both cultivars when stored at ambient humidity. When stored at high relative humidity (>95 per cent), weight loss was small and waxing was of little additional benefit.
