Abstract
The chilling injury and polyamine contents of cucumber were studied in the low temperature storage after heat treatment at 37 ℃ and 42 ℃ for 24 h and 12 h respectively.The cucumber chilling injury stored at 2 ℃ was delayed 2 days to occur by heat treatment at 37 ℃ and 42 ℃;the percentage and index of chilling injury in cucumber were decreased significantly(38.2%,0.17 and 39.3%,0.13 lower than control on the 6th day of storage by heat treatment at 37 ℃ and 42 ℃ respectively).The endogenous Put content in cucumber increased significantly,and was 2 times higher than control on 6th to 8th day of storage.The peak of endogenous Put content coincided with the occurrence of chilling injury.The content of endogenous Spd and Spm was enhanced and high level of endogenous polyamines was maintained in cucumber during low temperature storage.There was high correlation between endogenous polyamines level and chilling tolerance of cucumber.
