2.6. Determination of maturity advancement
Two reddest fruit per plant were harvested on 154 DAS and weighed, and measured for TSSC, skin colour, internal ethylene concentration and CO2 production using the same procedures outlined for the determination of quality at maturegreen stage. These fruit were oven-dried at 71 1 8C to a constant mass. Fruit water content was determined by subtracting fruit dry mass from fresh mass and expressed as % of fruit fresh mass.
