Inflorescence heights and number of siliques were determined for plants grown in soil in a temperature controlled growth cabinet under SL-conditions (PFD = 150 μmol⋅m-2⋅s-1) in the long- for 56 days after sowing. Seed weights and numbers as well as seed areas were measured after ripening and drying of the plants. The data represent the mean ± SE of n = 5 or n = 4∗ determinations. The numbers of replicates for seed area determinations are given in the table. A statistical analysis of growth parameters is contained in Doc S2, Table 1.
