摘　　要：检测低温(4℃)贮藏条件下转AcInv反义基因与否的马铃薯品系块茎中干物质、淀粉和还原糖含量变化的结果表明:随着低温贮藏时间的延长,各转基因品系块茎中干物质含量变化不大,淀粉含量虽有下降但较为平缓;转基因品系中的还原糖含量增加幅度比受体品种的明显降低,转AcInv反义基因的‘甘农薯1号’和‘大西洋’块茎抗低温糖化能力明显高于未转AcInv反义基因的品系。Transgenic lines of potato （Solanum tuberosum L.） tubers of ＇Atlantic＇, ＇Cardinal＇ and ＇Gannongshu No. 1＇ were stored at 4 ℃. The dry material, starch and reducing sugar contents were measured and analyzed. The results showed that the dry material content in transgenic tubers remained constantly or varied slightly; the starch content decreased gradually; and the reducing sugar content increased but the extents of increasing of ＇Atlantic＇ and ＇Gannongshu No. 1＇ were inferior to the control.
