| 摘 要： | 采用全反射X射线荧光分析法,研究10份欧李种质果肉中10种营养元素(P、S、K、Ca、Mn、Fe、Cu、Zn、Rb、Sr)特征,以及产地对京欧2号品种果肉中营养元素含量的影响。结果表明:欧李果肉中富含营养元素,特别是Ca含量较高,其中CH种质果肉中Ca含量最高(441.1 mg/kg,以鲜质量计);不同种质欧李果肉中营养元素含量差异较大,其中S、Fe、Ca和Sr含量在种质间差异的变异系数大于30%;主成分分析表明,P、S、K、Rb、Ca、Sr是欧李的特征元素;产地对欧李中营养元素影响较大,其中河北张北所产欧李营养元素含量更为丰富。

| Abstract: | The contents of nutrient elements such as P, S, K, Ca, Mn, Fe, Cu, Zn, Rb, and Sr were determined using total
reflection X-ray fluorescence spectrometry (TXRF) in the flesh of Chinese dwarf cherry from ten genotypes and Jing Ou 2
from 5 producing areas. The results indicated that Chinese dwarf cherry was a rich source of elements especially Ca, and
the highest Ca content (441.1 mg/kg fresh fruit ) was found in genotype CH among ten genotypes. A large variability in
nutritional element contents among the examined genotypes was obtained, because of the variation coefficients larger than
30% in S, Fe, Ca, and Sr contents. Principal component analysis was applied to the data matrix to evaluate analytical results.
It was found that P, S, K, Rb, Ca, and Sr might acted as eigenelements for the germplasm resource of Chinese dwarf cherry.
The fruit quality of nutrient elements was also significantly affected by producing area and the highest nutrient element
contents were found in Zhangbei county of Hebei province. |
