| 摘 要： | 选用8个不同熟期、综合性状良好、在各地生产上主栽的马铃薯品种为试验材料,分别对其顶部、中部和基部的淀粉粒度分布进行对比分析。结果表明:参试品种中顶部、中部、基部的中位径、体积平均径、面积平均径较大的品种为克新12,其次是克新17,较小的为东农303。在同一品种的顶部、中部和基部的中位径、体积平均径、面积平均径对比中,品种东农303、克新17、克新18、克新19中部最大,顶部次之,基部最小;品种克新16、克新20、大西洋为中部最大,基部其次,顶部最小;品种克新12顶部最大,中部次之,基部最小。马铃薯淀粉粒度分布呈现正态分布,粒度集中在0.76~314.69μm,大部分颗粒集中在18.73~155.23μm。

| Abstract: | Eight main potato cultivars with different mature and better integrated traits were selected as experimental materials,starch particle size distribution of top,middle and base part of different type potato tuber were analyzed comparatively.The results showed that：Kexin 12 was the bigger,Kexin 17 was middle,Dongnong 303 was lowest for median diameter,volume mean diameter and surface mean diameter of top,middle and base part of different type potato tuber,median diameter,volume mean diameter,mean diameter size of top,middle and base part were compared in the same variety,the middle was the biggest,the top part took second place and the base was the smallest in Dongnong 303,Kexin 17,Kexin 18,Kexin 19;the middle was the biggest,the base took second place and the top part was the smallest in Kexin 16,Kexin 20 and Atlantic＇s;top part was the biggest,the middle took second place,the base was the smallest for Kexin 12.Potato starch particle size distribution were normal distribution,particle size concentrated between 0.76 and 314.69 μm,the most of them concentrated between 18.73 and 155.23 μm. |
