摘　　要：块茎淀粉含量是马铃薯品种一个非常重要的品质性状,本研究对俄引薯1号、龙引薯1号、海伦3号3个不同熟期品种在生育后期不同阶段的块茎产量、淀粉含量以及淀粉产量的动态变化进行了研究。3个品种的马铃薯块茎产量从高到低的顺序为:龙引薯1号>俄引薯1号>海伦3号。随着收获期的延后,各品种的块茎产量逐渐增加,其中8月31日与9月7日间增长速度最快。淀粉含量在生育后期先增加后降低,呈抛物线趋势变化,但淀粉产量随着收获期的延后而逐渐增加。Starch content in tuber is a very important quality trait of potato. The dynamic changes in tuber yield, starch content and starch yield of the three different maturing potato varieties, Eyinshu 1, Longyinshu 1 and Hailun 3, were studied at different growth stages. Tuber yield of Longyinshu 1 was highest, followed by Eyinshu 1, and then Hailun 3. Tuber yield increased as harvest time was delayed, with a big jump from August 31 to September 7. Starch content was increased, and then decreased, following a para-curve, but starch yield was increased as the harvest time was delayed.
