 note = {論文(Article), Summary : We studied the effects of timing of gathering and the method of preparing florets of Vitis coignetiae Pulliat on the yield of pollen for artificial pollination. Florets were gathered from a male tree at 10％ or 50％ flowering within a spike, and two preparation methods, method A, florets crushed before drying; method B, florets dried without crushing, were compared. The pollen yield and germination rate were determined for the above four treatments with a combination of the timing of gathering and the method of preparation. The yield of pollen obtained from 50% flowering florets was significantly higher than from 10% flowering florets and that obtained from method A was significantly larger than from method B. The germination rate of pollen obtained from method B was significantly higher than from method A. Although the yield of pollen with germination ability obtained from 50％ flowering florets in method A and B were statistically the same, the purity of pollen was higher in method B. From these results, it was concluded that better pollen can be obtained for artificial pollination by gathering florets at 50％ flowering within a spike and drying immediately without crushing in preparation for pollen collection.},
