| 摘 要： | 通过交配设计结合花部性状调查对鹅掌楸(Liriodendron chktense Sarg.)与北美鹅掌楸(L.tulipifera Linn.)的繁殖资源分配与繁殖成效进行了比较.结果表明,鹅掌楸通过增加繁殖器官的数目以提高繁殖成效,而北美鹅掌楸则通过提高繁殖器官功效来保障繁殖成效.根据不同交配组合的子代出苗率分析表明,鹅掌楸总体的雄性繁殖成效高于北美鹅掌楸,而雌性繁殖成效低于北美鹅掌楸.

| Abstract: | The resources allocation and reproductive success were compared between Liriodendron chinense and L.tulipifera based on mating design trial and floral characteristics.Six adult trees,3 from L.chinense and 3 from L.tulipifera,were chosen as mating parents.By comparing the floral characteristics between Liriodendron chinense and L.tulipifera,we found that there was a significant interspecies difference existing in both reproductive strategy and reproductive success.To ensure their reproductive success,L.chine... |
