摘要： The rapeseed pod number is one of the major components for rapeseed yield. Pod morphology plays an important role in rapeseed plant development and function. In this paper, we studied the quantitative relationships between rapeseed pod architecture indices and the corresponding organ biomass, and presented a biomass-based model of pod geometric parameters of rapeseed (Brassica napus L.), designed to explain effects of cultivars and environmental conditions on rapeseed pods morphogenesis. Various model variables, such as pod length, pod diameter, pod angles, and corresponding organ biomass. The models were validated with the independent experiment data, and the results suggested that these variables in rapeseed were remarkably consistent in observation and simulation. The partitioning coefficient values of pod biomass (CPPB) had a significant level at p<0.001, and the RMSE values, and the d(a) values were 0.077 g g(-1), and 0.015 g g(-1) (n=62), respectively. In our descriptive models have a good mechanism and interpretation; the ratio of pod body length to pod biomass (RPLW); the ratio of the pod stalk tangent angle (RPSTW), and the ratio of the pod stalk and body angle (RPSBW) were analyzed initially, which are able to correlate the organ biomass with its morphogenesis. Thus, the growth model can be associated with the morphological model via the organ biomass, and the Functional Structural Rapeseed Models (FSRMs) have been expanded.
