Abstract
Tomato fruit-set failures pregnantly occur in winter under low light conditions.
They would result from the competition for assimilates.
TOMGRO, a tomato growth and development model, holds this hypothesis.
This work is an attempt to validate its development and abortion functions.
The growth and development parameters were measured on a tomato crop, in a controlled environment, in order to fit the different functions of the model.
The source-sink approach appeared to predict correctly growth, fruit-set and fruit "abortion". To improve the model, it is now necessary to study the relations between the competition for assimilates and dry matter partitioning.
