It is concluded that there are three reasons resulted in male-sterility by floral organs abormality as follows :(1) The stomium enlongates faster;(2) Anther filaments do not elongate sufficiently to position the locules above the stigma at anthesis;(3) The anther locules do not dehisce at the time of flower opening (although limited dehiscence occurs later).

anther：花药

為植物之雄性生殖器官,包括花丝(Filaments)及花药(anther)两部份,花药包含花粉粒,它们能被释放到空气中然后和其它花朵的柱头授粉. 花药位于花丝顶端,花丝迅速伸出,将花药推出花朵,使它们很好地悬垂下来与柱头分开,并在风中开裂.

anther：药

每个雄蕊由花丝(filament)和花药(anther)两部分组成. 花药是花丝顶端膨大成囊状的部分,一般由4个花粉囊(pollen sac)组成,花粉囊内产生大量花粉粒. 花丝常细长,基部着生在花托或贴生在花冠上. 花丝支持花药,使之伸展于一定的空间,

anther：花粉囊

这种能够自授粉的兰花名为Holcoglossum amesianum,为雌雄同体,在授粉期间可以将自己的花粉囊(anther)抗重力旋转360°,将花粉插入自己的柱头腔(stigma cavity) 中,因而不需要任何授粉媒介的帮助.

anther culture：花药培养

花藥培養(anther culture)是一種較新的方法,成熟的花藥放在含有維他命與生長調節劑的介質中培養. 在花粉粒中的單倍體管細胞進行分裂,產生含有20至40個細胞的原胚體(proembryos,又稱前胚或潛胚). 最終花粉粒漲破,釋放出單倍體的胚,試驗室中可以產生單倍體植物或透過化學藥劑的添加可誘...
