建立了新合成的结构干物质在地上部和根部之间的分配模型。它基于假设的分配函数，该函数取决于碳和氮基质的相对水平，参数决定控制点和控制程度。利用该模型研究了植物在稳态指数生长过程中的特定生长率、冠根比和冠根比活度(依赖于环境)之间的关系，并探讨了模型的暂态行为，得到了这些量的振荡。
A model for partitioning newly-synthesized structural dry matter between shoot and root is developed. It is based on a postulated partitioning function, which depends upon the relative levels of carbon and nitrogen substrates, with parameters determining the control point and also the degree of control. The model is used to investigate the relationships between plant specific growth rate, shoot : root ratio, and the specific activities of shoot and root (which depend upon environment), during steady-state exponential growth; the transient behaviour of the model is also explored and oscillations in these quantities are obtained.
