摘要

这项研究的目的是检验紫百合变种和毛叶紫百合变种的人工和自然杂交种的特征,并确认杂交种是否能够繁殖并在其原生栖息地繁殖。白腹滨鹬和毛足滨鹬人工杂交产生的第1子代(=F1,从下看)叶片形状与白腹滨蠊变种(=takahashii,从下来看)相同,并且F1也开有裂孔花和裂孔花。F1种子数为9.6粒/粒,明显低于白足类和毛足类的平均值38.2粒,但发芽率基本相同。自交第二代(=F2,从下起)的叶型显示出在紫百合复合体中发现的所有叶型,但毛叶型的比例相对较低。F2叶型恢复为白色的个体平均每粒产生31.4粒种子,这意味着生育能力得到了恢复。另一方面,F2 takahashii叶型的个体结出的果实平均每粒10.4粒,与Takahashiii相似。杂交实验的结果与实验室的结果相似,它们的原生栖息地在哪里。布尔明永山的白足目和毛足目都分布广泛,但高海市的种群数量很少,只分布在白足目与毛足目共同生长的地方。总结以上结果表明,高滨藻的物种形成是由白足目和毛足目之间的杂交完成的,并且通过cleistogamous胶囊以相对较小的种群维持了这些物种形成。

Speciation of Viola albida var. takahashii based on both artificial and natural hybridization between V. albida var. albida and V. albida var. chaerophylloides
The study aims are to examine the characteristics of artificial and natural hybrids between Viola albida var. albida (= albida, from below) and V. albida var. chaerophylloides (= chaerophylloides, from below), and to confirm if hybrids could be fertile and make populations in their native habitats. The 1st filial (= F1, from below) leaf shape produced by artificial crossing between albida and chaerophylloides was the same as that of V. albida var. takahashii (= takahashii, from below), and F1 bore also both chasmogamous and cleistogamous flowers. F1 seed number was 9.6 per cleistogamous pods, which was remarkably less than the average of 38.2 for albida and chaerophylloides, but the germination rate was all similar. The leaf type of self-crossed 2nd offsprings (= F2, from below) showed all leaf types found in the Viola albida complex, but the ratio of chaerophylloides leaf type was relatively low. Individuals whose F2 leaf type was restored to albida produced an average of 31.4 seeds per capsule, meaning that fertility was restored. On the other hand, individuals of F2 takahashii leaf type come to fruition a low average of 10.4 seeds per capsule, which is similar to that of takahashii. The results of crossbreeding experiment, where is their native habitats, were similar to that of laboratory. Both albida and chaerophylloids in Mt. Bulmyeong distribute extensively, but takahashii make a small population only in places where albida and chaerophylloides grow together. Summarizing the above results is suggesting that the speciation of takahashii was done by hybrid between albida and chaerophylloides, and these have been maintained with relatively small population by cleistogamous capsules.
