2.1. Plant material
Tradiro tomatoes (Lycopersicon esculentum Mill. cv Tradiro)
grown in a greenhouse were provided by the Ctifl (Centre Technique
Interprofessionel des Fruits et Légumes, France) for both sets
of experiments. The tomatoeswere picked by hand at the late green
stage (tomato colour code 3–4, Ctifl, France) and chosen according
to size to obtain an approximately homogeneous sample. Theywere
externally defect-free. The tomatoes were picked at the end of May
2006 for the first experiment (Experiment 1) and at the end of June
of the same year for the second experiment (Experiment 2).
