Water Stress Permanently Alters Shoot Architecture in Common Bean Plants
The effects of water stress on crop yield through modifications of plant architecture are vital to crop performance such as common bean plants. To assess the extent of this effect, an outdoor experiment was conducted in which common bean plants received ...

FSPM-P: towards a general functional-structural plant model for robust and comprehensive model development [PDF]
In the last decade, functional-structural plant modelling (FSPM) has become a more widely accepted paradigm in crop and tree production, as 3D models for the most important crops have been proposed.
