Characterization of Kalanchoë genotypes. (A) Flower and leaf morphologies of different Kalanchoë species and cultivars. Scale bars: 1.0 cm. (B) Pistil and style length. Values present means (±S.E.), n = 20. Values followed by different letters (small letters for pistils and capital letters for style) are significantly different (P ≤0.05) according to Tukey’s honestly significant difference test. (C) The viability and germinability of pollen samples. Pollen viability was determined by staining with 1% acetocarmine, pollen germinability was determined by incubation in liquid germination medium. Values presented are means (±S.E.), n = 3. Values followed by different letters (small letters for viability and capital letters for germinability) are significantly different (P ≤0.05) according to Tukey’s honestly significant difference test, genotype name followed by asterisks indicates values significantly different (P ≤0.05) between two performed pollen analyses according to t-test.
