Abstract
SummaryConcentrations of ten mineral elements (P, S, K, Ca, Mn, Fe, Cu, Zn, Rb, and Sr) were determined in 27 genotypes of Chinese dwarf cherry using total reflection X-ray fluorescence spectrometry. The results indicated that Chinese dwarf cherry was a rich source of mineral elements, especially Ca, Fe, and Zn, with the highest concentrations being 524, 24.2, and 4.86 mg kg–1 FW in genotypes C-12-5-7, A-9-1-3, and E-20-2-2, respectively. Among the 27 Chinese dwarf cherry genotypes examined, the coefficients of variation were > 30% for Rb, Fe, Ca, Sr, Zn, Mn concentrations, and 25 – 30% for P, S, K, and Cu concentrations. Principal components analysis was applied to the data matrix to evaluate the analytical results. Three principal components (PC1 – PC3) accounted for 75.6% of the total variance. The 27 Chinese dwarf cherry genotypes studied have potential benefits for human nutrition and healthcare research, as well as for genetic biodiversity research.
