| 摘 要： | 二重雌雄异型异熟,即雌雄功能按雄-雌-雄顺序分别表达,是有花植物中较为少见的异熟机制.槭属(Acer)大部分物种具有二重雌雄异型异熟的开花物候,且第一期雄花与第二期在形态上差别较大.为深入探讨花发育模式对花形态和开花物候的影响,本文应用石蜡切片技术和光镜技术,对色木槭(Acer mono)各个发育时期的3种类型花(雄花... |

| Abstract: | Duodichogamy,where individual plants produce two batches of male flowers that are temporally separated by a batch of female flowers,is the rarest temporal sexual system in flowering plants.Duodichogamy is present in some species of Acer,whose flowers of the first(male I) and second male phases(male II) differ morphologically.To explore the influence of floral development on flower morphology and phenology,we used paraffin methods and light microscopy to compare morphological and cytological differences amon... |
