The Effect of High-voltage Static Field on the Active Oxygen Metabolism System of Zaoyan Peach

Abstract

Abstract: In this paper, effects on activity of CAT and SOD, MDA contents and relative conductance of pericarp of "Zaoyan" peach using 100kV/m high-voltage electric static field(HVEF),were studied. The results showed that 100kV/m HVEF could effectively increase the activity of CAT and SOD, so as to keep the active oxygen in vivo on low level. HVEF could hold back the increase of MDA content and relative conductance in pericarp at the prophase of storage, but they increased quickly at the anaphase of storage. It was probably because that HVEF could not adjust the synegistic action of CAT and SOD successfully. As a result, the cell membrane was destroyed.

Key words: HVEF, CAT, SOD, MDA, relative conductance, peach
