From: Lanthanum Prolongs Vase Life of Cut Tulip Flowers by Increasing Water Consumption and Concentrations of Sugars, Proteins and Chlorophylls

Figure 5

Concentration of total soluble sugars in cut flower petals of 15 tulip varieties at the time of cutting (A) and at the end of vase life as a function of the preservative solution evaluated (B). Different letters in each column (variety) of each subfigure indicate statistical differences according to the Tukey test (P ≤ 0.05).
