Abstract: The effect of short time -100kV/m high voltage electrostatic field (HVEF) treatment on the post-harvest physiology of cucumber was studied in this paper. The results showed that the weight-losing of cucumber during storage was significantly controlled by short time HVEF treatment. Meanwhile the increase of the relative conductivity of cucumber peel was controlled while there was no significant difference between the respiration of cucumber under HVEF and control, which indicated that the short time HVEF treatment was not suitable to store fruit and vegetable.

Key words: high voltage electrostatic Field, cucumber, storage
