基于主成分分析的10个葡萄品种果实营养元素比较

Comparison of nutrient elements in 10 different varieties of grape fruits based on principal component analysis

以10个葡萄品种为试材,分别测定了果实中硼、钾、钙、镁、铁、锌6种营养元素,探究不同品种中营养元素间的差异性,以期为葡萄营养诊断提供理论依据。结果表明:在10个不同葡萄品种中营养元素间均呈显著差异;相关性分析表明:硼与铁、镁、锌呈显著正相关;钙与锌呈显著正相关;铁与锌呈显著正相关;且其他营养元素间差异不显著;主成分结果综合排名为:‘美人指’>‘红地球’>‘巨峰’>‘阳光玫瑰’>‘金手指’>‘葡之梦’>‘翡翠无核’>‘夏黑’>‘小蜜蜂’>‘紫甜无核’。该研究为葡萄实际生产奠定理论依据。

Ten grape varieties were as the test materials.The six nutritional elements of boron,potassium,calcium,magnesium,iron and zinc in fruits were measured.The differences of nutritional elements in different varieties were studied in order to provide theoretical basis for grape nutritional diagnosis The results showed that there were significant differences in nutrient elements among 10 different grape varieties;Correlation analysis showed that boron was positively correlated with iron,magnesium and zinc;There was a significant positive correlation between calcium and zinc;There was a significant positive correlation between iron and zinc;There was no significant difference among other nutrients;The main ingredients results comprehensive ranking is:‘Manicure Finger’>‘Red Globe’>‘Kyoho’>‘Sunshine Rose’>‘Gold Finger’>‘Portugal’s Dream’>‘Jade Seedless’>‘Summer Black’>‘Apis florea’>‘Purple sweet Seedless’.This study lays a theoretical foundation for the practical production of grape.
