| 1. | Examples include dioecious species where only one sex is present . 例如在雌雄异株种类中仅仅存在单性。 |
| 2. | The mating system can be changed in a quick and simple manner, from monoecy to dioecy . 用较快而简洁的方法使交配系统从雌雄同株变成雌雄异株。 |
| 3. | Endodeme is a deme composed of predominantly closely inbreeding but dioecious individuals . 同系同群种是由近亲繁育占优势,但雌雄异株的个体组成的同群种。 |
| 4. | Having the male and female reproductive organs borne on separate individuals of the same species 雌雄异株的在一个个体上产生雄性器官,而在另一同种的个体上产生雌性器官的 |
| 5. | Examples include the scale leaves of parasitic flowering plants or the reduced stamens in females of dioecious species 例如:寄生有花植物的鳞叶;雌雄异株种类的雌株的退化雄蕊。 |
| 6. | It is a dioecious plant . the female tree is different from the male in many aspects , such as karyotype analysis , pattern of peroxidase isozymes and shape of flower 银杏又是严格的雌雄异株,还没有发现雌雄同株现象,其雌雄株在染色体核型,过氧化物同工酶谱等都有较大差异。 |
| 7. | Beecheyana is one of the gynodiecious ficus spp ; the female syconium and male syconiu are simular outside syconium , but obviously different inside the syconium which showed the dimorphoism 牛奶榕为雌雄异株的榕属植物,雌雄榕果在榕果外部形态相似,在榕果内部有明显差异,呈现两型性。 |
| 8. | Routine breeding time is very long and its productivity also is low so that it restricts seriously early economy benefit and development of gingo 但是,银杏是雌雄异株植物,实生苗定植后一般需要20 30年才能开花结果,银杏常规育种时间长,效率低,严重制约了早期经济效益的提高和生产的发展。 |
| 9. | Examples include male and female plants in dioecious species , aerial and submerged leaves , alternation of gametophyte and sporophyte stages of a life cycle , and mesophyll and bundle - sheath chloroplasts 例如在雌雄异株物种中的雌性植物和雄性植物,气生的和被水浸没的叶片,生活史中的配子体与孢子体的交替,叶肉和维管束鞘叶绿体等。 |
| 10. | From study on their floral syndrome , it is possible to ascertain that p . meirilliana and its sister species p . cicutarrifolia have the same ancestor that is homostylyed , since the changing of environment conditions or visiting by insects , p . merrilliana becomes heterostylyed and seems to have envolved in a direction toward dioecy or subdioecy 根据花部综合特征,推测两物种是同一祖先的两个近缘衍生种,安徽羽叶报春的祖先可能是花柱同长的,并有可能向雌雄异株方向进化c5 |
