摘要：

To reconstruct 3D plant shape of greenhouse tomato, this paper presented the developmental rule to simulate the morphological architecture of greenhouse tomato plant and its organs, and main model parameters were derived from the periodic measurement and stochastic analysis. In the model, the whole architecture of tomato plant was consisted of a main stem and lateral branches, whose growth was considered as a succession of nodes and internodes. For the kinetics of individual organs, binomial law was used to simulate the random number of different truss along the stem, and markov process was applied to generate classical leaf architecture, Meanwhile we used cantilever beam theory to model leaf inclination. The expansion of individual organs was simulated by using beta distribution law. With their geometrical definition by computer graphics tool, the model output more realistic 3D architecture of tomato plant, and fitted very well with real plant, which proved that above developmental rules were reliable to the architectural characteristics of tomato plant. This research will provide a convenient computer software tool for the quantitative description and visualization for the growth of tomato plant.
