Abstract: The‘Qingshu 9’seed potatoes were used as experimental materials, which were treated with carvone of0.2 mL/kg every 6 weeks for 3 times, then the storage, physiology and planting indices were investigated in order to evaluate the storage effects of carvone on seed potatoes. The results showed that, compared with the control group, carvone treatment could reduce weightlessness and rotting rates of seed potatoes, inhibit the germination via regulating abscisic acid（ABA）, gibberellin（GA₃） and indoleacetic acid（IAA） contents, improve the superoxide dismutase（SOD） and catalase（CAT） activities, decrease the accumulation of MDA contents, and increase proline（Pro） contents, resulting in retarding the physiological aging of seed potatoes. Moreover, carvone treatment presented no adverse effects on field characters, yields and postharvest potatoes qualities. In conclusion, carvone treatment not only showed preferable storage and preservation effects on seed potatoes, but also would not affect the subsequent planting and production.
