Gynoecium and aggregate fruit ovoid.

雌蕊群和聚合果卵圆形。

The unisexual flower is caused by the selective abortion of androecium or gynoecium in the hermphroditic primondia.

单性花的发生是由于原两性花原基的雌蕊或雄蕊选择性败育所造成的。

The androecium were consisted of 3 stamens,two of which were connate ,separating or partial combination.

摘 要 对南瓜的两性花进行外部形态及结构的研究,结果表明:南瓜的两性花可有子房上位花、子房半下位花和子房下位花三种类型:花萼、花冠均为5,合瓣;雄蕊3,其中有两枚各由两个雄蕊合生而成,分离和部分联合,花药结构特殊,花粉发育正常;雌蕊具有单个或两个柱头及花柱。

Petals basally connate; androecium and gynoecium subequal to petal length species nos.

花瓣基部合生;雄蕊群和雌蕊群近等长于花瓣长度种类号。

Hypogyny The simple arrangement of flower parts in which the receptacle is expanded at the top of the pedicel in such a way that the androecium and the perianth arise from beneath the gynoecium giving a superior ovary.

下位式:是花的各部分位置的一种排列方式。花梗顶端的花托膨大,因此雄蕊和花被处于雌蕊的下方并使子房位于上方。

By observing and analyzing 3D structure of apple flower and inflorescence, we raised the 3D structure mathematical model of anthocaulus, receptacle, calyx, petal, androecium and pistil. At the same time, we get model parameter, integrate the apple flower and inflorescence topology structure information, reconstructed 3D structure of apple flower and inflorescence.

通过对苹果花及花序形态结构的观测分析,分别提出了描述花柄、花托、花萼、花瓣、雄蕊和雌蕊三维形态结构的数学模型,并提取了模型的控制参数;进一步整合苹果花及花序的拓扑结构信息,实现了苹果花及花序的三维重建。

Firstly, mathematical models for describing the 3D structure of anthocaulus, receptacle, calyx, petal, androecium and pistil are proposed basing on observing and analyzing the 3D structure of apple flower and inflorescence. At the same time, parameters for controlling these models are extracted. Secondly, the reconstruction of 3D structure of apple flower and inflorescence is implemented by integrating its topological structure information.

通过对苹果花及花序形态结构的观测分析,分别提出了描述花柄、花托、花萼、花瓣、雄蕊和雌蕊三维形态结构的数学模型,并提取了模型的控制参数;进一步整合苹果花及花序的拓扑结构信息,实现了苹果花及花序的三维重建。

On the floral apex the different classes of organ primordia appeared in the following sequence: calyx, corolla, androecium and gynoecium, and they had overlapped with each other when occurring in turn.

花原基分化形成花的整个过程符合一般的分化顺序:花萼原基-花冠原基-雄蕊原基-雌蕊原基,且各原基在分化顺序上存在交叉。

Epigyny The type of flower structure in which the perianth and androecium are inserted above the gynoecium, giving an inferior ovary, fused with the receptacle.

上位式:指花被和雄蕊群着生于雌蕊群之上的花的结构类型。子房在下方,与花托融合。

The process can be divided into 6 stages of differentiation: early, involucrum, single flower, perianth, androecium, and gynoecium.

花芽形态分化可分为花芽分化初始期、总苞分化期、花原基分化期、顶花花被分化期、雄蕊分化期和雌蕊分化期6个阶段。
