摘　　要：为探讨块茎重量对不同淀粉型马铃薯加工品质的影响,本研究选用高淀粉品种克新27号、维拉斯、安农薯1号和低淀粉品种荷兰15号和龙渝薯1号为试验材料,块茎重量设置25、50、100、150和200 g共5个处理,测定了不同重量块茎的干物质含量、淀粉含量和还原糖含量等加工品质指标,分析了不同重量块茎加工品质的差异。结果表明,高淀粉品种克新27号、维拉斯和安农薯1号块茎重量在25~150 g时,干物质含量和淀粉含量随块茎重量的增加呈不断增加的趋势;在150~200 g时,上述指标未发生显著变化。低淀粉品种荷兰15号和龙渝薯1号块茎重量在25~100 g时,干物质含量和淀粉含量随块茎重量的增加呈不断增加的趋势;在100~200 g时,未发生显著变化。高淀粉品种克新27号、维拉斯和安农薯1号块茎重量在25~200 g时,还原糖含量随块茎重量的增加呈不断降低的趋势;而低淀粉品种荷兰15号和龙渝薯1号块茎重量在25~200 g时,还原糖含量一直稳定在较高水平。综上,高淀粉马铃薯品种重量为150~200 g的块茎加工品质较优。In order to investigate the effect of tuber weight on the processing quality of different starch type potatoes,high-starch varieties Kexin 27,Vilas and Annongshu 1 and low-starch varieties Holland 15 and Longyushu 1 were selected as experimental materials,and tuber weights were set at 25,50,100,150 and 200 g.The processing quality indexes such as dry matter content,starch content and reducing sugar content of tubers with different weights were determined,and the differences of processing quality among tubers with different weights were analyzed.The results showed that the dry matter contents and starch contents of high-starch varieties Kexin 27,Vilas and Annongshu 1 increased with the tuber weight increasing from 25 to 150 g.The above indexes were no significant change at 150-200 g.When the tuber weight of Holland 15 and Longyushu 1 were 25-100 g,the dry matter content and starch content increased with the increase of tuber weight,and there was no significant change at 100-200 g.When the tuber weight of high-starch varieties(Kexin 27,Vilas and Annongshu 1)were 25-200 g,the reducing sugar content decreased with the tuber weight increasing.On the other hand,the lowering sugar concentration remained consistently at a high level when the tuber weight of the low-starch types(Holland 15 and Longyushu 1)were 25-200 g.In conclusion,high-starch potato varieties weighing 150-200 g could improve tuber quality.
