【摘要】 通过对14份桑树种质资源桑芽营养成分进行测定与分析，旨在为优质菜用桑品种的选育提供种质资源储备与理论基础。结果表明，桑芽营养含量丰富，14份种质桑芽维生素C含量为7.67～15.3 mg/100 g，可溶性糖含量为2.75～7.88 mg/g，总酚含量为13.88～30.33 g GAE/kg，类胡萝卜素含量为0.009～0.018 mg/g，叶绿素a含量为0.244～0.505 mg/g，叶绿素b含量为0.088～0.190 mg/g，可溶性蛋白含量为13.12～18.79 mg/g，总蛋白含量为25.71～37.30 g/100 g，氮含量为4.12～5.97 g/100 g。基于主成分分析结果显示，综合桑芽营养品质较好的桑树种质资源为粤椹大10。更多还原

【Abstract】 This study analyzed and tested the nutritional components of mulberry buds from 14 mulberry germplasm resources cultivated in the mulberry resource nursery of the Economic Crops Research Institute of Hubei Academy of Agricultural Sciences,this study aims to provide a theoretical basis and resource reserve for the breeding of high-quality vegetable-oriented mulberry bud varieties.The results showed that mulberry buds are rich in nutrients. The vitamin C content of the 14 germplasm resources ranged from 7.67 to 15.30 mg/100g,the soluble sugar content from 2.75 to 7.88 mg/g,the total phenol content from 13.88 to 30.33 g GAE/kg,the carotenoid content from 0.009 to 0.018 mg/g,the chlorophyll a content from 0.244 to 0.505 mg/g,the chlorophyll b content from 0.088 to 0.190 mg/g,the soluble protein content from 13.12 to 18.79 mg/g,the total protein content from 25.71 to 37.30 g/100g,and the nitrogen content from 4.12 to 5.97 g/100g. Through principal component analysis and comprehensive ranking,the germplasm resource "Yueshen Dashi" was identified as having the best comprehensive nutritional quality.更多还原
