摘　　要：分别采用染色法和萌发法测定亚洲百合、东方百合、麝香百合品种群的部分栽培品种以及野生种的花粉活力。染色法的测定结果表明:野生种的花粉活力最高,接下来依次为东方百合、麝香百合、亚洲百合品种群的花粉活力最低。萌发法的测定结果表明:野生种的花粉活力最高,接下来依次为麝香百合、亚洲百合,东方百合品种群的花粉活力最低。两种方法的比较结果表明:染色法测定花粉活力是一种较为初步的、简单的方法,它仅能给育种工作提供最基础的花粉存活信息,但不能反映花粉活力的全部信息,而萌发法不仅可以反应花粉的存活状况,而且能进一步反映出花粉的萌发能力。所以,在百合的授粉过程中,需要将染色法的测定结果和萌发法的测定结果综合比较,来指导选配亲本,提高杂交育种的成功率。The pollen vitality of lilies （wild varieties, Oriental hybrids, Longiflorum, Asiatic hybrids） were examined by methods of dyeing and germination. The results which used method of dyeing showed that pollen vitality of wild varieties was the highest, pollen vitality of Oriental hybrids, Longiflorum hybrids in turn, Asiatic hybrids has the lowest pollen vitality. The results which used method of germination showed that pollen vitality of wild varieties was the highest, pol- len vitality of Longiflorum hybrids and Asiatic hybrids in turn; pollen vitality of Oriental hybrids was the lowest. Com- pared the results two methods showed that the method of dyeing was a simple way which can provide basic things about pollen vitality and cannot illustrate the vital power of the pollen completely, germination method not only can gave information about vital power of the pollen but also pollen germinated ability. It needs to be combined the method of dyeing and germination in the lily＇s pollination.
