摘　　要：以青薯9号原种为试材,采用香芹酮处理,总剂量为0.6 mL/kg,每6周处理1次,每次处理剂量0.2 mL/kg,在种植前6周停药,考察香芹酮处理对种薯贮藏、生理及田间种植指标的影响,评价香芹酮对种薯的贮藏效果。结果表明:与对照相比,香芹酮处理可降低贮藏期间种薯失重率和腐烂率,调控脱落酸(ABA)、赤霉素(GA_3)和吲哚乙酸(IAA)的含量,抑制种薯发芽,并提高超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性,降低丙二醛(MDA)的积累,提高脯氨酸(Pro)的含量,延缓种薯的生理老化,且对田间性状、产量和采后马铃薯品质无不良影响。香芹酮处理既对种薯具有较好的贮藏保鲜效果,也不影响种薯的后续种植生产。The‘Qingshu 9'seed potatoes were used as experimental materials,which were treated with carvone of 0.2 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.
