Fruits of Actinidia chinensis Planch cv. Luoyang-2 and A. deliciosa C. F. Liang, et A. R. Ferguson cv. Hayward were obtained from the experimental orchard of Chinese gooseberry in Luoyang, Henan Pro-vince. The fruits were kept in cold storage with artificially lowered ethy-lens concentration after harvest. The rate of ethylene production and respiration, electrical conductivity, pectin content, interal ethylene, O2 and CO2 concentration and flesh firmness of the fruit were determined. The results showed that the highest peak of ethylene production occurred 12 days after harvest while climacteric appeared. They are synchronous in progress. The electrical conductivity during senescence remained high. The ethylene production of 'Hayward' was lower than that of 'Luoyang-2' at 0 ℃. The flesh firmness and the content ratio of protopectin to pectin of 'Hayward' was higher than that of 'Luo-yang-2'. This result shows why 'Hayward'has better storage behaviour than that of 'Luoyang-2'. In CA storage, the rate ethylene production of the fruit was reduced. Ethylene in the storage environment can be quickly scrubbed by using ethylene absorbing beads and softening of the fruit can be reduced. Of the many indices used to measure senescence of fruit tissue, the content ratio of protopectin to pectin and flesh firmness for the fruit of Chinese gooseberry are the most important. The changes of these indices are apparent signs which indicate the degree of senescence of the fruit.
