Relationship between fruit softening, ethylene production and respiration in Japanese persimmon 'Hiratanenashi'.

Persimmon cv. Hiratanenashi fruits were harvested at intervals and treated with ethanol. At every stage of development, ethanol treatment produced an increase in ethylene and carbon dioxide evolution even though the fruits were still firm. Ethylene evolution either preceded or coincided with a rise in respiration rate, independent of fruit maturity. Ethylene production increased rapidly 24 h after ethanol treatment, whereas the flesh began to soften after 48 h. Softening and ethylene evolution became more rapid with increasing ethanol concentration. Ethanol treatment also removed astringency and hastened calyx abscission. Carbon dioxide depressed the rates of ethylene evolution and respiration and delayed the rate of fruit softening. Ethylene is thought to be an activator of the fruit softening mechanism in Hiratanenashi.
