摘要:

【目的】 研究外源腐胺(Putrescine,Put)处理对黄皮甜瓜冷害的控制效果,筛选适宜的外源腐胺处理浓度,为生产中甜瓜果实采后冷害调控提供理论依据。【方法】 以黄皮甜瓜新密3号为试材,分别用0、1.0、1.5和2.0 mmol/L 4个不同浓度外源Put处理后,置于5℃、相对湿度75%~80%条件下贮藏,定期统计黄皮甜瓜果实冷害指数,测定果实失重率、色泽、硬度、可溶性固形物、抗坏血酸和细胞膜透性等指标。【结果】 2 mmol/L外源腐胺可显著控制黄皮甜瓜采后冷害发生,维持其果实硬度,延缓色泽变化,抑制细胞膜透性的增加,使果实可溶性固形物(SSC)和抗坏血酸(VC)含量保持较高的水平。【结论】 2 mmol/L外源腐胺处理可有效控制黄皮甜瓜果实采后冷害的发生。

Abstract:

【Objective】 To explore the control effects of exogenous putrescine (Put) treatment on chilling injury of yellow melon fruits and select the appropriate exogenous Put treatment concentration. 【Method】 Xinmi 3 yellow melon fruits were studied as the test material, which were treated with four different concentrations of external Put at 0, 1.0, 1.5 and 2.0 mmol/L, and placed at 5℃ and 75%-80% relative humidity.The chilling injury index was counted regularly, and weight loss rate, color, hardness, soluble solids, ascorbic acid and cell membrane permeability of yellow melon fruits were measured during the storage period. 【Result】 The result showed that 2 mmol/L exogenous Put could significantly control the occurrence of chilling injury, maintain the firmness, delay the color change, inhibit the increase of cell membrane permeability, and keep the soluble solids (SSC) and ascorbic acid (VC) content at the higher level of yellow melon fruits. 【Conclusion】 2 mmol/L exogenous Put treatment can effectively control the occurrence of chilling injury of yellow melon fruits.This result provides a theoretical basis for the regulation of chilling injury of melon fruit in production.
