Fig. 5: Fruit development in three strawberry varieties is accompanied by differences in the accumulation of soluble sugars.

a Fruits from three F. × ananassa varieties (cv. Benihoppe and breeding materials L281# and L84#) were harvested and photographed in the green (G), white (W), turning (T), and ripe (R) stages. Scale bars, 1 cm. b Dynamic accumulation of the main soluble sugars in fruits from the three strawberry varieties. Values are the means ± standard errors (n = 3). Three biological repeats were included. The concentrations of sucrose, glucose, and fructose were determined by HPLC and expressed in mg/g fresh weight (FW)
