Modeling the response of peach fruit growth to water stress.
We applied a semi-mechanistic model of fresh matter accumulation to peach fruit during the stage of rapid mesocarp development. The model, which is based on simple hypotheses of fluid flows into and out of the fruit, assumes that solution flow into the fruit increases with fruit weight and transpiration per unit weight, and decreases with the maximum daily shrinkage of the trunk, which was used...
متن کاملUsing L-systems for modeling source-sink interactions, architecture and physiology of growing trees: the L-PEACH model.
Functional-structural plant models simulate the development of plant structure, taking into account plant physiology and environmental factors. The L-PEACH model is based on the development of peach trees. It demonstrates the usefulness of L-systems in constructing functional-structural models. L-PEACH uses L-systems both to simulate the development of tree structure and to solve differential e...
متن کاملUsing L−Systems for Modeling the Architecture and Physiology of Growing Trees: The L−PEACH Model
Carbohydrate partitioning represents a central problem of process−based models of tree growth because of the coupling between carbon partitioning, growth, and architecture. PEACH was an early, sink−driven, carbohydrate partitioning model for simulating reproductive and vegetative growth of fruit trees. Carbon partitioning in that model was based on the hypothesis that a tree grows as a collecti...

متن کاملDoes variability in shoot carbon assimilation within the tree crown explain variability in peach fruit growth?
A three-dimensional model of radiative transfer and leaf gas exchange was used to quantify daily carbon (C) assimilation of all fruit-bearing shoots (FBS) in an early maturing 6-year-old peach tree (Prunus persica L. Batsch) with a heavy crop load. For a sample of FBS (n=36), growth of fruit and leafy shoots was measured every 1-2 weeks from 24 days after bloom (DAB) until harvest, between 93-1...
