Abstract

Taking three genotypes (small-fruit-type, medial-fruit-type and big-fruit-type) Chinese wild dwarf cherry (Prunus humilis) which living in the same circumstances as tested materials, the mineral nutrient components and amino acid contents were determined, to provide the basis for wild dwarf cherry germplasm resources development and effective component utilization. The results showed that, Chinese wild dwarf cherry fruits were rich in mineral nutrient and amino acid and the contents were different within three genotypes. The mineral nutrient contents of small-fruit-type fruits were higher than that of big-fruit-type, especially calcium element was most obvious, the maximum was 6751.07 mg/kg and minimum was 581.07 mg/kg. The total amino acid content, essential amino acids content for big-fruit-type higher than the small-fruit-type. Maximum content were respectively 7648.60 mg/100 g and 1307.72 mg/100 g, the essential amino acid content accounted for 19.75~22.83% of total amino acid. The studies suggested that Chinese wild dwarf cherry was a natural and effective calcium and amino acid supplement to people.
