| Abstract:In order to study the dwarfing mechanism of apple rootstocks, this review summarizes the dwarfing mechanism of apple’s rootstocks from four aspects, including biological characteristics, anatomical structure, physiological and biochemical, and molecular biology. The future research work should firstly focus on the differences of tree water metabolism between different apple’s rootstocks, then explore physiological and biochemical changes. Secondly, study on production, state, and the laws of transportation and degradation of various hormones in different apple’s rootstock trees. In addition, with the help of molecular biology techniques, intensive study, such as signal transduction, synthesis of GA and many hormone synergy, should be conducted as well. |
