Table 4.
Stomatal characteristics of polyploid and diploid R. fortunei plants.
| Ploidy Level | No of Evaluated Stomata | Stomata Length (μm) | Stomata Width (μm) | Stomata Index (Length/Width) | Stoma Area (μm2) | Stoma Density (mm−2) |
|---|---|---|---|---|---|---|
| Diploid | 30 | 27.30 ± 0.66 c | 21.19 ± 1.18 c | 1.30 ± 0.07 a | 454.02 ± 27.83 c | 164.79±11.85 a |
| Tetraploid | 30 | 34.07 ± 1.93 b | 30.41 ±1.87 b | 1.12 ± 0.06 b | 814.77 ± 82.39 b | 78.93±7.72 b |
| Octoploid | 30 | 42.67 ± 2.99 a | 38.89 ± 3.00 a | 1.10 ± 0.07 b | 1307.44 ± 176.26 a | 52.40±5.38 c |
Thirty stomata were measured for each ploidy level, and mean values ± SE in the same column followed by different lower letter are significantly different at p < 0.05 according to Duncan’s test.
