The reticulate evolution caused by hybridization, introgression and lineage sorting may be an explanation for the molecular phylogenetic incongruence.
叶绿体系统树与核基因系统树之间的冲突，可能是由杂交、渐渗、谱系分选造成的网状进化引起的。
Thus we speculate that GI (control of flowering time) may have experienced speciation- related selection, which further accelerated its lineage-sorting divergence between the species.
不同的选择压力使得GI的进化速度相对较快，从而加速了黄山松和马尾松的物种分化。
