Within-plant spatial variability in the production and demand for assimilates may have major implications for the formation of fruits. Gu et al. propose an FSP model for cotton (Gossypium hirsutum) based on local pools to quantify the variability of local carbohydrate availability within a plant.
This model is plausible and simulates cotton performance effectively in terms of leaf area dynamics, dry mass allocation and transport of carbohydrate. Spatial variability of local carbohydrate availability has is captured as an emergent property in the model. CottonXL is a tool to explore the underlying mechanism of fruit abortion and branching pattern in cotton.
