    Abstract:

    Pear is one of the major fruit in China and favorite by domestic and foreign consumers due to its nutritional value and health efficacy. Pear flower is corymb inflorescence and belongs to the multi-flowered type. Fruit setting rate of inflorescence has significant influence on the yield of fruit trees. Artificial control of flowers and fruits is a measure to regulate the amount of fruit set in the tree, to ensure the yield and fruit quality maximizing the commercial profile. Understanding the mechanism of inflorescence formation is of interest to increase fruit yield and improve fruit quality. This paper reviews the evolution of inflorescence, the process of inflorescence development, fruit setting position of inflorescence, effects of endogenous hormones on floral formation, and regulation of related genes on floral formation, etc. Moreover, the future prospective is proposed, in order to provide ideas for the research on pear inflorescence formation.
