Pollination systems of Salix miyabeana and Salix sachalinensis were studied at a riverside in northern Japan in order to measure the balance of wind pollination and insect pollination. In 1996, 19 clones of each species were selected, and seed-set success by a net-bagging (to exclude insect visitation) and an artificial pollination (to remove pollen limitation) were compared to by natural pollination. For S. miyabeana, the same experiment was repeated in two populations in 1997. Proportion of seed set through wind pollination dominated in both species in this study. Pollen limitation was common under natural conditions, and S. sachalinensis relied more on insect pollination for seed production than S. miyabeana. Meteorological factors such as precipitation and hours of sunshine during the flowering season influenced the potential reproductive activity of the willow between years. In the wet and cloudy spring of 1996, clones which obtained high seed set depended more on insect pollination for both species, whereas in the dry and sunny spring of 1997, such clones depended more on wind pollination for S. miyabeana. Because the efficiency of wind pollination seemed to be more sensitive to fluctuating weather conditions than insect pollination, insect pollination was considered to play an assurance role for seed production in these willows.
