摘要
以内蒙古地区21种资源类型欧李果实为试材,分析比较了不同资源类型欧李果实钙素营养含量差异和变化特点,并进行了聚类评价,以期为后续的资源研究及应用提供参考依据。结果表明:试验经聚类分析筛选出高钙资源2份及高活性钙资源9份,不同资源类型欧李果实的总钙、活性钙、水溶钙及果胶钙含量均有所差异。不同果肉颜色和不同酸度欧李果实的钙素营养均表现不同,红色和浅红果肉的果实活性钙、水溶钙及果胶钙含量整体上均高于桔黄果肉的果实;随着果实酸度增加,表现为总钙含量下降、组分钙含量上升的趋势,但不同酸度果实的各钙素含量之间差别不明显。分别以总钙和活性钙及其组分为参数,采用平均联接(组间)法对欧李资源进行聚类,均划分为高、中、低含量3种类型;3种类型果实的总钙含量及活性钙含量均有明显差异,且果实活性钙含量的区别主要体现在果胶钙方面。
Twentyone resource types of Cerasus humilis fruit in Inner Mongolia area were used as materials,and the differences and variations of calcium content of Cerasus humilis fruit in different resource types were analyzed and compared,and cluster evaluation was carried out,in order to provide reference for subsequent resource research and application.The results showed that two parts of high calcium resources and nine parts of high active calcium resources were screened by cluster analysis,and the contents of total calcium,available calcium,soluble calcium and calcium pectate of Cerasus humilis fruit were different in different resource types.The calcium nutrition of Cerasus humilisfruit with different flesh color and different acidity was different,and the contents of available calcium,soluble calcium and calcium pectate in red and light red flesh were generally higher than those of orange flesh.With the increase of fruit acidity,the total calcium content decreased and the component calcium content increased,but the difference between the calcium content of fruits with different acidity was not obvious.Total calcium,available calcium and their components were divided into parameters,and the average join(between)method was used to cluster the Cerasus humilis resources,and they were divided into three types:high,medium and low content.There were obvious differences in total calcium content and available calcium content of the three types of fruits,and the difference in available calcium content of fruits was mainly reflected incalcium pectate.
