The development of a tomato crop can be managed by plant type, climate, irrigation and fertilization. The grower manages the development with leaf plucking and pruning. In the project, the New Crop, latter measures appear to have a strong effect on the distribution of assimilates.
By removing more leves in an early stage, less assimilates will move to the leaves and more to the fruit. This is a striking result. In the coming season we will perform a project in which we repeat one of the treatments of the past year. The follow-up project aims to investigate how the physiological processes; breathing of leaves and fruits, photorespiration and transport and distribution of assimilates by changing the leaf picking strategy in combination with the leaf area index (the leaf surface area per m2). We want to understand the processes better. Is the behaviour in winter with assimilation lighting different from that in the summer when there is plenty of natural light? In practice it might have the implication of different crop management strategies during a year if we want to produce year round tomatoes. For each season, the grower must take appropriate measures.
