| 摘 要： | 为研究氯化钙处理对具有机械伤的番茄果实生理特性的影响,本实验用1 mmol/L氯化钙(CaCl2)处理机械伤的番茄果实,将处理后的番茄于20℃贮藏,测定贮藏期间番茄生理品质和抗氧化酶活性的变化。结果表明:经过CaCl2处理含有机械损伤的番茄果实,可以维持番茄在贮藏期间的感官品质,降低腐烂率;与对照组相比,CaCl2处理可维持番茄果实的硬度和色度,延缓贮藏期间维生素C(VC)含量的下降;同时,抑制丙二醛(MDA)的积累,提高过氧化物酶(POD)、抗坏血酸过氧化物酶(APX)、多酚氧化酶(PPO)的活性。因此,1 mmol/L CaCl2处理具有机械损伤的番茄可以有效维持其在贮藏期间的品质,延长货架期。

| Abstract: | To study the effect of calcium chloride(CaCl2)treatment on postharvest physiology characteristics of tomato with mechanical damage,1 mmol/L CaCl2 was used to treat the tomato fruits,then the treated tomatoes were stored at 20℃,the changes of physiological quality and antioxidant enzyme activity were determined. The results showed that CaCl2 treatment could effectively maintain the sensory quality of mechanically damaged tomato fruits and reduce the dacay rates during storage at 20℃.Compared with the control group,CaCl2 treatment at 1 mmol/L delayed the degradation of VC content,inhibited the accumulation of MDA,and enhanced the activity of POD,APX and PPO. These results suggested that 1 mmol/L CaCl2 treatment could effectively maintain storage quality and prolong the shelf life of mechanically damaged tomato fruit stored at 20℃. |
