Abstract Various leaf removal treatments were applied during winter and summer to tomato variety Brioso. The standardwinter treatment knew 33% removal of small leaves in the top of the canopy while in total 11-12 leaves per stemwere maintained. The two other winter treatments each knew 55% leaf removal and maintaining 8-9 and 10-11leaves, respectively. The standard summer treatment was the same as in winter. One summer treatment had noleaf removal and therefore a high leaf area, and one summer treatment had 66% leaf removal at the 4th to 5thtruss with approximately the same leaf number as the standard. It was concluded that 55% leaf removal in winterunder the ambient weather conditions has weakened the crop towards the end of winter. This is therefore a riskystrategy. Production was in the first place related to fruit weight and in the second place to the number of fruits.Leaf removal in winter results in a better dry matter partitioning to the fruits, while leaf removal mid-way canopydepth in summer results in a poorer dry matter partitioning to the fruits. An important question is how the excessof assimilates that is accumulated during summer by a small-fruited tomato can be utilized for production.
