| 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. | |
