【摘要】 测定了2℃和13℃下黄瓜及4℃和16℃下番茄中的腐胺和亚精胺含量。结果表明，冷害发生前，黄瓜和番茄中的多胺含量呈上升趋势，冷害发生后，其含量呈下降趋势；温度预处理在减轻黄瓜冷害的同时，延长了腐胺含量增加的过程。更多还原

【Abstract】 The correlation of polyamines with chilling injury of cucumber and tomato and the treatments for alleviating chilling injury were studied, the chilling injury (CI) symptoms of the "Xia Feng "cucumber appeared after 3 days exposure to 2℃, the levels of put in cucumber increased before the appearance of the CI occured. The temperature preconditioning treatment significantly reduced CI in cucumber,and the levels of put increased at the same time, but the levels of Spd in preconditioned cucumber was slightly lower than the control. The CI symptoms of the "Jia Fen"tomatos appeared after 15 days exposure to 4℃,under this temperature, Put levels in tomatos rose between days 1 and 15, the levels fell after 15 days, but remained higher than the control (16℃ ). The levels of Spd in 4C increased between days 1 and 3, and decreased after 3 days.更多还原
