As one of the most traditionally cultivated fruit trees, apricot (Armeniaca vulgaris L.)is native to China. The key problems in the current apricot production of China are pistil abortion, flower dropping, and low fruit setting, which reduced the economic income of apricot growers and limited the development of apricot industry, so raising the apricot fruit setting rate is the important approach for the current apricot production. The mineral elements are the foundation for optimized growth, high yield and top quality. The diagnosis of leaf mineral nutrition is useful for the understanding of mineral elements needs, absorption and accumulation status inside fruit trees, and is thus an area of fundamental importance for investigating the causes of apricot flowers abortion, the apricot nutrition-effective breeding, and fertilizer application to improve the apricot fruit quality. According to the result of the leaf analysis technique applied on the apricot in the last few years, this paper summarized the methods of apricot leaf mineral nutrition analysis, the factors related, the dynamic changes of leaf mineral nutrition content, the relationships between the leaf mineral element contents and apricot yields, fruit qualities etc. The future works on the apricot mineral nutrition research are prospected.
