Storage of Japanese Persimmon of Pollination Constant Non-astringent Type in Polyethylene Bags with Ethylene Absorbent

Abstract

The present paper reports storage of fruits of ‘Fuyu’ and ‘Fukurogosho’ (Diospyros Kaki Thunb.), pollination constant non-astringent cultivars, using ethylene absorbent and the most desirable gas conditions for storage.1. Fruit softening was most greatly affected by ethylene and next by CO2 in the inside and outside of fruits. In order to delay fruit softening, it is necessary firstly to reduce ethylene concentration, and secondly to increase CO2 concentration, but not so high as to induce browning of fruit apex.2. The use of 0.04mm polyethylene bags containing ethylene absorbent delayed softening of ‘Fuyu’ and ‘Fukurogosho’ fruits.
