Abstract

Abstract: In this paper， effect on respiration， ethylene production， soluble solids and content of carbon dioxide the fruit core of‘Yali’pear using一100 kV／m high—voltage static electric field (HVEF)were studied．The results showed that HVEF had significan t effect on the respiration with a 60 d delayed peak and ethylene wi th a 60 d delayed pe ak but a half value compared to the control．Compared wi th control fruit，Furthermore， HVEF reduced loss of solub le solids of ‘Yali’ pear and inhibited browning of the fruit． To restrain function of respiration
caused by HVEF may msulted from a metabolized turbulence of Fe2 ／Fe3 an d restrained electric transfer of respiration chain．
