Carotenoid (A) and sugar (B) content during watermelon fruit development. The content of carotenoids including lycopene, β-carotene and lutein, and sugars including sucrose, glucose and fructose, was measured at four stages of fruit development: immature white (10 DAP), white-pink flesh (18 DAP), red flesh (26 DAP) and over-ripe (34 DAP). DAP: days after pollination. Each data represents mean ± SE (n = 2).
