Adhesion and breakage point analysis of petals of different genotypes. A, The breakage point is given for petals that were adhering to a glass plate and were separated by force. Tissue indicates tissue disrupted, leaving the remaining petal on the glass slide, and Nanoridge indicates petal lifted off the glass slide without recognizable tissue damage. n = 30 to 80. B, The force was determined with which the petal-glass slide contact was broken. Samples that detached with a force lower than 0.5 g could not be handled (disrupted line). All wild-type (WT) samples and 60% of the lacs2 samples were thus set to 0.5 g. Different letters indicate significant differences as determined by ANOVA/posthoc Tukey-Kramer test at P < 0.05.
