Figure 5
Fluorescence micrographs of squashed styles of “Hongpisu” harvested after different pollination treatments. (a1) Germination of pollen grains on stigma 2 h after self-pollination. (a2) Growth of pollen tubes in style transmitting tissue 6 h after self-pollination. (a3) Growth inhibition of pollen tubes in style transmitting tissue 8 h after self-pollination. (a4) Twisted pollen tubes 12 h after self-pollination. (b1) Germination of pollen grains on stigma 1 h after cross-pollination. (b2) Growth of pollen tubes in style transmitting tissue 8 h after cross-pollination. (b3) Growth of pollen tubes in style transmitting tissue 12 h after cross-pollination. (b4) Pollen tubes arrive at the base of the style 24 h after cross-pollination.
