Studies on the Fertilization of Panax ginseng

Pollen tube penetration and fertilization of Panax ginseng were investigated, the results of which we re summarized as follows: Pollen tube started to grow into the stigmatic tissue about five hours after pollination, reached to the embryo sac by about 16 hours after pollination. Fertilization of secondary nucleus occured about 18 hours after pollination, while the egg cell was fertilized seven hours later than the fusion nucleus. First division of the primary endosperm nucleus was observed taking place around 25 hours af ter pollination, but the fertilized egg cell underwent its first division about 20 hours later than the primary endosperm nucleus.
