| 摘 要： | 对杜鹃花孢粉学、繁育系统及传粉生物学方面的研究进展进行了分析，提出杜鹃花属植物繁殖生物学未来的研究可以主要从以下几个方面开展：（1）探讨杜鹃花属孢粉学线形结构的花粉呈现的进化意义;（2）在中国喜马拉雅地区，研究不同地点的相同物种和不同物种繁育系统，分析杜鹃花繁育系统多样性的相关因子，了解传粉系统及传粉昆虫的多样性，揭示杜鹃花属的传粉者特点;（3）选取合适的基因片段，重建杜鹃花属的系统，通过系统树找出可能是杂交起源的种类，纠正经典分类学在杜鹃花属系统位置构建方面的偏差;（4）对比不同杂交群体的繁殖生物学特性，找出传粉昆虫对不同亲本和杂交个体施加选择压力的差别，明确在物种的杂交形成过程中传粉昆虫对生殖隔离的选择作用。 |

| Abstract: | In this paper,we reviewed the research progress of Rhododendron,including palynology,breeding system and pollination biology in recent years.Finally,future studies on reproductive biology of Rhododendron should address these 4 important questions:(1) What is the evolutionary significance of thread-forming structure of pollen in Rhododendron?(2) Comparative studies on reproductive biology from different species and different populations in the same species should be carried out,to find effecting factors on breeding systems and pollinators’ diversity as well as understand pollinating characters in Rhododendron.(3) Selecting suitable genes to find possible species from hybrid origin and constructing a much more scientific phylogeny,thereby solving problems in classical botanical taxonomy.(4) Understanding reproductive traits of hybrids from different populations and realizing the different selective pressures on parental and hybrid species,to discover the function of reproductive isolation imposed by pollinators in the process of hybridizing speciation. |
