| Abstract:
Dry matter distribution is an important factor determining the crop yield. A preliminary model for dry matter distribution in crops with indeterminate growth like cucumber and tomato is described and some results are shown. The simulated dry matter distribution is primarily regulated by the sink strengths of the individual (clusters of) fruits. The sink strengths of individual (clusters of) fruits can be quantified by their potential growth rates, i.e. the growth rates under conditions of non-limiting assimilate supply. The simulated dry matter distribution among individual clusters of tomato fruits corresponded reasonably well to measured data. | |
