Involucre是一个在植物学中常用的术语,它通常用于描述植物的花序结构。具体来说,这个词可以从以下四个方面进行解释:
1. 定义:Involucre是指一种位于花序基部的苞片排列,其主要功能是保护花序和花朵。这个结构通常会有多层,有时会形成一个杯状的形状。
2. 解剖学:Involucre的组成通常包括苞片和苞片的柄,其大小和形状因植物物种而异。有些植物的involucre比花朵本身更明显,例如石南科植物。
3. 分类学:Involucre是植物分类学中一个重要的特征,常用于鉴定植物的分类和种属。例如,菊科植物的involucre可以根据其大小和形状进行分类。
4. 生态学:Involucre对于植物的保护和吸引动物传粉起着重要作用。有些植物的involucre上含有甜味或有香味,吸引昆虫或鸟类来传播花粉。
以下是5个中英例句:
1. The involucre of the Asteraceae family is usually composed of several rows of overlapping bracts.(菊科植物的苞片通常由几排重叠的苞片组成。)
2. The size and shape of the involucre can help distinguish between different species of Eupatorium. (苞片的大小和形状有助于区分不同种类的紫菀属植物。)

involucre是指掩盖或保护花或顶芽的一层或多层叶片或鳞片,通常为花序或花序的基部,而不是花本身。它可以是单独的或与其他部分融合在一起。
