No significant pattern was detected, which suggested extensive pollen flow. Alternatively, the failure to detect genetic structure within population may be due to intraspecific competition during recruitment and development process, resulting in "thinning effect" within populations.3.
虽然梭梭的种子散布能力有限，但花粉流有可能是空间遗传结构不显著的原因之一：另一个可能的解释是在种群更新和发展过程中，由于种内竞争的增强而发生了自疏现象。
