The effect of ethrel in aqueous solutions at 250, 500 and 1000 ppm and ethylene released
from ethrel at 250, 500 and 1000 ppm was evaluated on fruit ripening of white-and pink-
fleshed guava fruits. Ripening was enhanced in all treated fruits of both guava types at all
concentrations used. The ripening rate progressively increased with increase in
concentration. Ethylene released from ethrel was more effective in triggering fruit ripening
than dipping fruits in aqueous solution of ethrel. Depending on concentration, ripening was …

The effect of ethrel in aqueous solution and ethylene released from ethrel was evaluated on
fruit ripening of 'Kitchner','Dr Knight'and 'Abu-Samaka'mango. Ripening was enhanced in all
treated fruits of the three cultivars at all concentrations used. The ripening rate progressively
increased with increase in concentration. Ethylene released from ethrel was more effective
in triggering fruit ripening than dipping fruits in aqueous solution of ethrel. Depending on
concentration and cultivar, ripening was 1–3. d faster in fruits dipped in 500 and 1000 ppm …
