Abstract: Armeniaca vulgaris Lam. was the special fruit tree of China, which had great development prospects. However, there were many difficulties during the course of the apricot cultivation, and the current researches on the physiological mechanism in the apricot were still not enough to deal with all of these difficulties. This paper summarized the progress of researches on the abortion of flower organs, the use of mineral nutrient elements, the drought control physiology and the chill-proof physiology of kernel-apricot (Armeniaca vulgaris Lam.). These might provide a substantial base for the further development of the production and the research on kernel-apricot.
