以掃描電子和光學顯微鏡檢探究旋花科植物冤絲子(Cusc ula a/lstralis) 花部的發育情形。花之各部始原依專片、雄 蕊、花瓣及心皮之順序出現。除記述發育時花部的特徵外並和旋花科及其它植物比較。兩個心皮先端尚未癒合之前, 胚珠很早就出現於雌蕊上,此點較為特殊。又起源為基生的胚珠因具不完全隔板而看似中軸胎座。
The initiation and developmental features of floral organs of Cuscuta australis R. Br. were examined with the scanning electron and light microscopy. The sequence of initiation of the floral organs in a flower bud is that of sepals, stamens, petals and gynoecium. The first sepal is initiated laterally; the remaining four sepals 副.e initiated in helical succession. The five petals are initiated alternating with the sepals. The five stamens are initiated slightly early, and alternating with the petals. The five scales arise at the base of stamen, when two stigma are visible. Two opposite carpels arise with four ovules and fuse toward apex gradually, after all other floral organs are initiated. The five sepals ma仙re fir哎, curve at the tips and enclose th巴other organs. The five petals are delayed in develop, and elongated later after tetralobed anthers are visible in stamen. The two carpels after subsequent growth and fusion develop into two stigma and two short styles. The four ovules are exposed before the complete fusion of carpels. They are partially separated by incomplete septum afertward.
