【摘要】 将带有固定液的凹形载玻片放置于开花期间大豆田间的不同位置,通过统计载玻片上截获花粉的数量,推测风为大豆传粉的可能性。结果表明,2002年在大豆生产田,每小时每平方毫米截获花粉的数量为0.004个;不同高度截获花粉的数量存在明显差异,在相同时间内,40cm高处截获花粉的数量是26cm高处的2倍;2003年在不育系和恢复系1∶1相间种植的杂交大豆制种田,累计120分钟没有截获到大豆花粉。更多还原

【Abstract】 The impact of wind to pollen flow was analyzed by catching pollen number using the concave glass slide with fixed liquor in the soybean field during anthesis.The result indicated that the average number was 0.004 grains/ mm~2 in 2002,it was different in different height and grains in 26cm was double of in 40cm.The sterile line and restorer line were grown in 1∶1 in 2003,and no grain was caught in total 120 minutes in the field.更多还原
