It can be concluded that significantly larger variations between day and night temperatures than commonly applied will not reduce the pollen production and pollen germination potential in tomato as long as the mean temperature is kept constant. The overall conclusion was that the 27/14°C treatment was superior to the other two temperature treatments (24/17°C and 30/11°C DT/NT). The preharvest temperature regimes did not affect the storability of the tomatoes.
