Research On The Functional-Structural Plant Model Based On The L-systems

Mathematical and computational models can help people get more deeply understand the growth and development of plants. It provides a way to test our assumptions about the behavior of the real plant from reality to abstract, providing some simple understanding of the observed phenomenon, allowed the researchers to do the quantitative prediction under the new conditions. The functional-structural plant model is suitable for these types of studies. Functional-structural plant model(FSPM) captures the complex relationship between the plant structure and physiological processes both controlled by the environment. The purpose of the thesis is to study the expression of plant morphology and carbon biomass allocation method in plant tissues and organs. The research took Arabidopsis as an example, proposing L-systems growth succession rules of the Arabidopsis organs based on growth observational data and the structural features of stems, leaves and flowers, simulating the transmission and distribution on carbohydrates in plants based on the carbon transport-resitance allocation model, and defined the growth curve function to describe the dynamic growth of the leaves and internodes in different stages of development. The example has proved that the growth equation can accurately simulate the Arabidopsis dynamic growth process, and the growth curve has been coincided with the actual growth curve. The research provides a physical infrastructure for studying the plant model methods.
