Size of floral organs. A) Developmental stages of flowers from inflorescence of the primary shoot are shown. Note the smaller size of xi-1/xi-2/xi-k flowers and flower buds. Bar = 1 mm. B) Mean length of peduncles, sepals, petals and flower buds (±SD). Opened flowers and flower buds of the inflorescences (from main stems) were selected for measurements. The average size of floral organs of xi-1/xi-2/xi-k is smaller than in wild type (WT). Asterisks indicate statistical significance (* p < 0.05, ** p < 0.01, and *** p < 0.001, unpaired t-test with Welch correction, n = 6-12).
