Microspore characteristics of the cola-mutant in comparison to the wild-type.
| Flower type | n | Pollen viabilitya (%) Mean ± SD | S+U Pollenb (%) Mean ± SD | Size of viable microsporesc | |
|---|---|---|---|---|---|
| Length (μm) | Wide (μm) | ||||
| Mean ± SD | Mean ± SD | ||||
| Wild-type (epigynous) | 10 | 68.67 ± 6.89 a | 1.36 ± 2.05 a | 32.4 ± 5.1 a | 16.2 ± 3.1 a |

n, tested plants, for each plant 400 pollen were evaluated.
a
Uniformly green-yellow stained pollen.
b
Number of small (S) and underdeveloped (U) pollen.
c
Twenty fertile microspores of each were measured. Different letters in a column indicate significant differences (p < 0.05; t-test).
