Pollen viability and germination among the 23 tested Thai Musa cultivars. Data are mean ± SE of six biological replicates. Different letters within the same column indicate significant differences analysed by Duncan’s Multiple Range Test at P ≤ 0.01. N/A (not applicable) indicates pollen non-germination.
