In order to discuss the effect of two types of high voltage electric field treatments on the storage quality of tomato fruit, “Zhaoyan219” tomato was taken as the experimental material, and the two treatments of the negative high voltage intermittent electrostatic field (namely steady electric field) that was 200kV/m and 2h/d and alternative electric field pretreatment (namely alternative electric field) that was -200～200kV/m, 40kHz and 2h on the effect of qualities of mature green tomato fruit during the storage quality(13℃) were studied. The results indicate that the two treatments can lower the decay incidence (P<0.05) remarkably. The decrease of firmness of tomato fruit, the content of soluble sugar and chlorophyll content of tomato peel and the increase of titratable acid and lycopene content are postponed by the effect of high voltage electric field treatments. That is how the infirmness is delayed and the qualities of tomato fruit are improved. 
