中文摘要：

以樱桃番茄（Solanum lycopersicum cv.Messina）果实为材料,研究外源水杨酸甲酯（methyl salicylate,MeSA）处理对果实冷害发生及多胺积累的影响。结果表明：该处理减缓了樱桃番茄果实冷害症状的发展,降低了冷藏过程中果实的冷害指数、腐烂率和细胞膜的透性,显著促进了冷藏之前果实内源亚精胺（spermidine,Spd）和精胺（spermine,Spm）的积累,并提高了冷藏过程中腐胺（putrescine,Put）和Spm的含量。MeSA处理减轻樱桃番茄果实的冷害与果实内源多胺的积累有关。

英文摘要：

Cherry tomatoes（Solanum lycopersicum cv.Messina） were used to study the effects of exogenous methyl salicylate（MeSA） on chilling injury and endogenous polyamine level.The results indicated that compared with the control,MeSA treatment inhibited the occurrence of chilling injury in cherry tomato,decreased chilling injury index,decay incidence and electrolyte leakage.The accumulation of endogenous spermidine and spermine levels was significantly promoted in MeSA-treated fruits before cold storage and the levels of putrescine and spermine were increased during storage.These results indicate that the reduced chilling injury in cherry tomatoes after MeSA treatment may be due to an increase in polyamine level.
