The correlation of polyamines with chilling injury of cucumber and tomato and the treatments for alleviating chilling injury.

Symptoms of chilling injury appeared in cv. Xia Feng cucumber fruits after 3 days of exposure to 2 deg C; levels of putrescine increased before the symptoms occurred. A temperature preconditioning treatment (13 deg ) significantly reduced chilling injury; levels of putrescine increased at the same time, but spermidine levels were slightly lower in preconditioned fruits than in the control. In cv. Jia Fen tomatoes, chilling injury symptoms appeared after 15 days at 4 deg . Putrescine levels rose between days 1 and 15, then fell, but still remained higher than in the controls at 16 deg . At 4 deg , spermidine levels increased between days 1 and 3 and then decreased.
