| Wild type | 86.03% ± 6.39% | 10.41% ± 7.07% | 3.58% ± 0.67% | N1 = 74 |

| OXP | 58.34% ± 0.58% | 31.38% ± 0.18% | 10.29% ± 0.40% | N1 = 160 |
| N2 = 511 |
a
If a wild-type pollen tube path showed less than one encircling of the papilla cell after penetration, it was scored as <1. If the pollen tube encircled the papilla cell at least once, it was scored >1.
b
The growth direction of a pollen tube was away from the style.
