iences na Numerical simulation of plant growth has been facing a bottleneck due to the cumbersome compu-lex plant topological structure. In this article, the authors present a new nt growth, GreenLab, overcoming these difficulties. GreenLab is based on he plant structure. Fast simulation algorithms are derived for deterministic omputation time no longer depends on the number of organs and grows he age of the plant. This factorization finds applications to build trees very efficiently, in the context of geometric models, and to compute biomass production and distribution, tural models. tion, functional structural plant models, GreenLab, structural factor-nt ap
