Height and mass were determined on fully senesced primary inflorescence stems of the three double mutants, wild type (WT), and the corresponding parental lines. The data represent the average ± standard deviation of at least 24 replicates per line. The cell-wall residue (CWR) was determined gravimetrically after extraction and is expressed in % dry weight ± standard deviation (n = 10). No significant differences were observed at the 0.01 significance level (ANOVA, pairwise comparison with Holm correction)
