一个通用的异速生长模型已经被用来预测种子植物叶、茎和根生物量之间的种内和种间比例关系。一个大的纲要的常设器官的生物量采样跨越广泛的采样类群栖息在不同的生态栖息地的分析支持模型预测的关系，并定义了地面和地下生物量分区的边界条件。这些典型的生物量关系是不敏感的亲缘关系（针叶树与被子植物）和平均当地环境条件的变化。因此，该模型识别和定义的限制，指导种子植物生物量分配策略的多样化。
A general allometric model has been derived to predict intraspecific and interspecific scaling relationships among seed plant leaf, stem, and root biomass. Analysis of a large compendium of standing organ biomass sampled across a broad sampling of taxa inhabiting diverse ecological habitats supports the relations predicted by the model and defines the boundary conditions for above- and below-ground biomass partitioning. These canonical biomass relations are insensitive to phyletic affiliation (conifers versus angiosperms) and variation in averaged local environmental conditions. The model thus identifies and defines the limits that have guided the diversification of seed plant biomass allocation strategies.
