摘要: 为挑选出营养物质含量丰富且因硝酸盐含量较低的叶用莴苣品种,对25份不同品种叶用莴苣的Vc、有机酸、粗纤维、可溶性糖、可溶性蛋白和硝酸盐6个营养指标的含量进行测定,并利用模糊数学的隶属函数法计算不同品种叶用莴苣的每个营养指标的隶属函数值,对其营养品质进行综合评价。结果表明,不同品种叶用莴苣间营养物质含量存在较大差异,并且即便是同一品种不同来源的叶用莴苣,其营养成分含量差异也很明显。在本研究中,综合品质最优的有2个品种,分别是‘N-I’和‘大速生’,此外,还发现部分品种叶用莴苣营养物质含量丰富但却因硝酸盐含量较高而影响其综合品质,为日后优化育种指明了方向。

Abstract: In order to evaluate the lettuce (Lactuca sativa L.) varieties which have high content of nutrients and low content of nitrate, we determined six nutritional quality parameters including Vc, organic acids, crude fiber, soluble sugar, soluble protein, and nitrate of 25 lettuce varieties in this experiment. Then we calculated the nutritional value of each nutritional quality parameter using the membership function from the fuzzy math. The results showed great differences of the nutritional quality among different lettuce varieties. Moreover, the nutritional quality also had great differences among the lettuces of the same variety but from difference resources. In our research, there were two varieties with high nutritive quality, they were ‘N-I’ and ‘Dasusheng’. And also from the results we found that some varieties were rich both in nutrition and nitrate, providing the direction for optimum breeding.
