Four classes of partition models , empirical models , functional equilibrium models , optimal control models , and source-sink models were reviewed in this paper. The empirical models were widely used with minimal mechanistic assumptions. The function equilibrium models were successful in the simulation of the rootPcanopy ratio at the periods of the vegetative growth , but were poor to simulate portioning among other organs. The optimal control models were suitable for the modeling under the equilibrium state. The source2sink models were the most powerful and mechanistically based models capable of simulating dynamic photoassimilates partitioning between any organs of the plants.
