  • ‘Sunrise’papaya fruits were pre-treated by 1-methylcyclopropene（ 1-MCP） for 10,20,and 30 days and then treated with ethephon at 0. 5 g·L-1to observe their storage quality and softening changes as well as their ‘rubbery’texture. As compared with the 1-MCP treatment,the 1-MCP + ETH treatments can promote drop in fruit firmness to some extent,and accelerated the degradation of pectin,which is due to the treatment of ethephon improving Endo-1,4-xylanase and Beta- galactosidase activities. The increase of cellulose and lignin content was closely related to the water loss during storage. Considering the effects of ethephon treatment at different time on measurement indicators,the 1-MCP +（ 20 d） ETH treatment produced the best effect on alleviation of the ‘rubbery’phenomenon of papaya fruits.

Abstract: ‘Sunrise’papaya fruits were pre-treated by 1-methylcyclopropene（ 1-MCP） for 10,20,and 30 days and then treated with ethephon at 0. 5 g·L-1to observe their storage quality and softening changes as well as their ‘rubbery’texture. As compared with the 1-MCP treatment,the 1-MCP + ETH treatments can promote drop in fruit firmness to some extent,and accelerated the degradation of pectin,which is due to the treatment of ethephon improving Endo-1,4-xylanase and Beta- galactosidase activities. The increase of cellulose and lignin content was closely related to the water loss during storage. Considering the effects of ethephon treatment at different time on measurement indicators,the 1-MCP +（ 20 d） ETH treatment produced the best effect on alleviation of the ‘rubbery’phenomenon of papaya fruits.
