Ripe red tomatoes (stages 8–9 of the colour screening scale
for tomatoes [1]) were harvested throughout a 9-week period
(one harvest date per week for all four treatments). Fruit were
weighed and average fresh weight (FW) per fruit was
determined. Six to 10 red fruit from each treatment were
selected for chemical analysis. Simultaneously, young green
fruit taken from each of the four treatments harvested 10 days
after anthesis were analysed (three fruit with two replicates
each, beginning from the second harvest date of ripe fruit on).
