When there was only one pollen donor, gene flow frequency was in direct proportion to the pollen density.(8) The strong pollen competition from self-pollination might contribute to the very low outcrossing rates and gene flow frequencies in rice varieties.(9) The study of rice pollen flow showed that with the artificial disturbance of pollen dispersal there were pollen grains detected at 90 m from the pollen sources.

9对水稻花粉流的研究显示，在赶粉的实验条件下，于远离花粉源的90 m处仍然检测到花粉分布，回归分析显示水稻的花粉可以传播100 m以上，甚至在远离花粉源的200 m的距离处仍然可能有花粉分布，这表明水稻的花粉可以传播非常远的距离。
