Indehiscent

释义 Definition

indehiscent(形容词):(植物学)不裂开的;不自动开裂散播种子的。常指果实成熟后不会沿特定裂缝裂开来释放种子(如某些坚果、翅果等)。

例句 Examples

The plant produces indehiscent fruits that do not split open when ripe.
这种植物结的果实是不裂开的,成熟时也不会裂开。

Unlike dehiscent pods that burst to release seeds, this species has indehiscent structures, so dispersal relies on animals or wind.
与会爆裂散种的裂果荚不同,这个物种的结构是不裂开的,因此传播往往依赖动物或风力。

发音 Pronunciation (IPA)

/n.dhs.nt/

词源 Etymology

来自拉丁语构词:**in-**(表示否定,“不”)+ dehiscere(“裂开、张开”)。其中 dehiscere 与“张口/裂缝打开”的含义相关,进入现代科学英语后常用于描述果实或孢子囊的“开裂/不开裂”特征。
