摘要
以15个培育的无限生长型番茄为材料,从营养物质与次级代谢物(总酚与类黄酮)方面评价不同番茄种质资源营养和次生代谢物及其相关性。结果表明:各材料间可溶性蛋白、可溶性糖、总酸度、番茄红素、Vc、总酚与类黄酮含量差异显著,硝酸盐含量差异不显著。材料844与845番茄红素含量分别为17.858 mg/100 g与14.407 mg/100 g,是加工番茄标准(8 mg/100 g)的2.2倍与1.8倍;867与826的总酚与类黄酮含量显著高于其它种质资源,达到8.364 mg/100 g、6.799 mg/100 g,24.363 mg/g与21.879 mg/g。营养组分高的番茄其总酚与类黄酮含量也相对较高,其中表现最佳的是867,828与863次之,最差的是850与847。相关性分析表明番茄中次级代谢物(总酚与类黄酮)与Vc间呈极显著关系(p<0.01)。从综合营养组分和次级代谢物(总酚和类黄酮)方面来说,867番茄材料的品质最佳。
The material is 1 5 cultivated infinite growing tomatoes. The nutrition and secondary metabolites of different tomato germplasm resources and the correlation were evaluated from the aspects of nutrients and secondary metabolites(total phenols and flavonoids). The results showed that the content of soluble protein, soluble sugar, total acidity, lycopene, Vc, total phenol and flavonoids were different among materials, but there was no significant difference in nitrate content. The lycopene content of 844 and 845 reached the standard of processed tomatoes(8 mg/100 g), 17.858 mg/100 g and 14.407 mg/100 g, and it is 2.2 times and 1.8 times of the processed tomato standard(8 mg/100 g). The total phenols and flavonoids content of 867 and 826 were significantly higher than those of other varieties, reaching 8.364 mg/100 g, 6.799 mg/100 g, 24.363 mg/g and 21.879 mg/g. Comprehensive analysis of the nutritional quality and secondary metabolites, the contents of secondary metabolites in tomatoes with good nutritional quality were relatively high, with 867, 828 and 863 performing well, while 850 and 847 were the worst. However, the correlation analysis showed that the secondary metabolites(total phenols and flavonoids)in tomatoes had only significant correlation with Vc(p<0.01). Finally, the quality of 867 tomato was the best in terms of its nutritional composition and secondary metabolites(total phenols and flavonoids).
