摘　　要：本文以潍县萝卜为试验材料,研究了不同含量蔗糖溶液(0、0.4%、0.8%、1.2%、1.6%、2.0%)处理对潍县萝卜芽苗菜生长发育及营养品质的影响。结果表明,0.8%蔗糖溶液处理下,潍县萝卜芽苗菜的单株鲜质量以及果糖、葡萄糖、可溶性总糖、维生素C、总酚、类黄酮、异硫氰酸盐含量最高;0.4%蔗糖溶液处理下,潍县萝卜芽苗菜的苗高最高;1.2%蔗糖溶液处理下,潍县萝卜芽苗菜的游离氨基酸含量及SOD酶活性最高;1.6%蔗糖溶液处理下,潍县萝卜芽苗菜的可溶性蛋白质及硫代葡萄糖苷含量最高。主成分分析结果显示,14个品质指标中提取出了3个主成分,累积贡献率达到87.200%。其中主成分1的方差贡献率最大,且在果糖、葡萄糖、可溶性总糖含量等指标上载荷值较高,说明糖分含量对萝卜芽苗菜品质的影响较大。各处理综合得分结果表明,0.8%蔗糖溶液处理的得分最高,说明0.8%蔗糖溶液处理萝卜芽苗菜的品质最好。因此可见,一定含量的蔗糖溶液可以有效促进萝卜芽苗菜的生长发育,显著提高其营养品质,且以0.8%蔗糖溶液处理效果最佳。In this paper,Weixian radish was used as the test material.The effects of different contents of sucrose solution(0,0.4%,0.8%,1.2%,1.6%,2.0%)on the growth and nutritional quality of Weixian radish sprouts were studied.The results showed that the fresh weight per plant and the contents of fructose,glucose,total soluble sugar,vitamin C,total phenols,flavonoids,isothiocyanate in Weixian radish sprouts were the highest under the treatment of 0.8% sucrose solution.The seedling height of Weixian radish sprouts was the highest under the treatment of 0.4% sucrose solution.The free amino acid content and the SOD activity in Weixian radish sprouts were the highest under the treatment of 1.2% sucrose solution.Weixian radish sprouts had the highest content of soluble protein and glucosinolate under the treatment of 1.6% sucrose solution.The results of principal component analysis showed that three principal components were extracted from 14 quality indices,and the cumulative contribution rate was 87.200%.Among them,the variance contribution rate of principal component 1 was the highest,and the loading values of fructose content,glucose content and total soluble sugar content were higher,indicating that sugar content had a greater impact on the quality of sprouts.And the comprehensive score of each treatment showed that the 0.8% sucrose solution treatment had the highest score,indicating that the quality of radish sprouts under the treatment of 0.8% sucrose solution was the best.Therefore,a certain content of sucrose solution could effectively promote the growth and development of radish sprouts and significantly improve their nutritional quality.And the treatment with 0.8% sucrose solution had the best effect.
