Germination ratio and pollen tube length in vitro. (A) Pollen grains from gVPS41-GFP+/− vps41−/− transgenic plants germinate in vitro. (Scale bars, 50 μm.) (B) Percentage of germination of vps41 pollen (n = 435) and vps41/gVPS41-GFP (n = 415) pollen 3 h after germination. Error bars indicate SD; P > 0.1. (C) Pollen tube length of vps41 pollen (n = 48) and vps41/gVPS41-GFP pollen (n = 70) 3 h after germination. Error bars indicate SD; P > 0.1.
