Rosette and individual leaf area increase upon Suc treatment. A and B, Plants were germinated on different Suc (sucr) concentrations (0 [control], 6, 15, or 30 mm), and the average rosette area (A) and average individual leaf area (B) were measured at 21 DAS. Cot, Cotyledons; Lx, leaf position x in the order of appearance on the rosette. Values are means of three biological repeats with their se. Rosette and leaf area were measured for six to 10 plants in each repeat. C, Third leaf area of plants germinated on 15 mm Suc or germinated on Suc-free (control) medium (No transfer) and transferred at 9 DAS to 15 mm Suc or control medium, measured at 21 DAS at a light intensity of approximately 65 µmol m⁻² s⁻¹ or at a lower light intensity of 50 µmol m⁻² s⁻¹. Values are means of three biological repeats with their se. Leaf area was measured for an average of 18 leaves in each repeat. Asterisks indicate adjusted P < 0.05 for log-transformed values in A and B, mixed models (see Supplemental Methods S1).
