Characterization of polyploid plants
| Ploidy level | Length of leaf blade (cm) | Width of leaf blade (cm) | Length of petiole (cm) | Width of petiole (cm) | Plant height (cm) | Width of stem (cm) | Number of leaves |
|---|---|---|---|---|---|---|---|
| Diploid | 22.0 ± 0.4 b | 11.2 ± 0.3 b | 3.1 ± 0.1 b | 1.2 ± 0.0 b | 12.6 ± 0.5 c | 3.4 ± 0.1 b | 13.0 ± 0.8 b |
| Tetraploid | 31.4 ± 1.2 a | 19.5 ± 2.5 a | 4.3 ± 0.1 a | 1.9 ± 0.4 a | 17.6 ± 0.5 b | 4.6 ± 0.0 a | 15.7 ± 0.5 a |
| Hexaploid | 8.9 ± 0.5 d | 4.5 ± 0.1 d | 2.0 ± 0.1 c | 1.1 ± 0.0 c | 11.0 ± 0.8 c | 4.3 ± 0.2 a | 5.3 ± 0.5 d |
| Octaploid | 13.7 ± 0.8 c | 5.8 ± 0.3 c | 1.5 ± 0.1 d | 1.9 ± 0.0 b | 33.3 ± 0.9 a | 4.1 ± 0.2 a | 9.7 ± 0.5 c |
Length and width of leaf blade, length and width of petiole, plant height and width of stem were measured 3 months after acclimatization. For each ploidy level, 10 plants were used for the measurements. Different letters indicate significant differences at p < 0.05, as determined by Tukey’s HSD test after arc-sine transformation of the data.
