| 摘 要： | 以鸭梨果实为材料，研究了一100 kV／m高压静电场处理对果实呼吸强度、乙烯释放量、可溶性固形物含量和果心二氧化碳含量变化的影响 试验结果表明，高压静电场处理使鸭梨果实的呼吸跃变推迟了60 d，但不改变峰值的高低，同时使乙烯释放高峰推迟60 d，且峰值只有对照的1／2左右。高压静电场处理对抑制可溶性固形物的损失和果心褐变具有显著效果。进一步的研究表明，高压静电场处理使铁离子的代谢紊乱，呼吸链电子传递受阻可能是其抑制呼吸作用的主要原因。

| Abstract: | In this paper, effect on respiration, ethylene production, soluble solids and content of carbon dioxide the fruit core of 'Yali' pear using - 100 kV/m high-voltage static electric field (HVEF) were studied. The results showed that HVEF had significant effect on the respiration with a 60 d delayed peak and ethylene with a 60 d delayed peak but a half value compared to the control. Compared with control fruit, Furthermore, HVEF reduced loss of soluble solids of ' Yali' pear and inhibited browning of the fruit. To restrain function of respiration caused by HVEF may resulted from a metabolized turbulence of Fe2 + /Fe3 + and restrained electric transfer of respiration chain. |
