複數 caryopses或caryopsides
n. [植] 穎果;殼果
When they were the same subspecies, the development of big grain varieties was slower than the small, and finally the dry weight of caryopsis was heavier;
同一亞種間,小粒品種發育時間短,大粒品種發育時間長,最終穎果幹重大于小粒品種。
Anthocyanidin firstly pigmentizes at the part of caryopsis away from embryo, then gradually extends to the part near embryo and makes the whole pericarp pigmentized.
穎果的遠胚端最早沉積花色素,以後逐漸延伸到胚端并使整個果皮着色;
The caryopsis growth and endosperm development of colored rice were basically the same as conventional rice, with the exception in its anthocyanidin accumulation in the pericarp.
除果皮沉積花色素等色素外,有色稻穎果的生長、胚乳發育與常規水稻品種基本相同。
A comparison of the caryopsis development, rice quality characteristics and the size, pattern, structure of the endosperm amyloplasts (starch granules) in the two indica rice varieties was made.
比較了兩個籼稻品種穎果的發育,籽粒的主要品質性狀以及胚乳澱粉體的大小、形狀、結構等特性。
It can be concluded that caryopsis ventral shape, sculpture, and foveola are very useful characteristics for the identification of species and the inference of interspecific relationships in Eleusine.
䅟屬植物的穎果腹面形狀、紋飾、表面小孔直徑及平均密度等性狀,可為種類鑒定及種間關系分析提供有價值的證據。
在植物學中,caryopsis(中文譯名:穎果)是一種單種子的不開裂果實類型,其特點是果皮(pericarp)與種皮(seed coat)完全融合,形成一體化的結構。這類果實常見于禾本科植物(Poaceae),例如小麥、水稻、玉米等主要糧食作物。
穎果的結構包括三個主要部分:
與瘦果(achene)不同,穎果的果皮和種皮在發育過程中完全黏合,這是禾本科植物適應風媒傳播和幹旱環境的進化特征。例如,小麥籽粒在研磨成面粉時,果皮和種皮會共同形成麸皮,而胚乳則成為面粉的主要成分。

caryopsis(穎果)是植物學中一種特定類型的果實,常見于禾本科植物(如小麥、大麥、玉米等)。以下是詳細解釋:
定義與結構
caryopsis 是一種單種子、不開裂的幹果,其特點是果皮(子房壁)與種皮緊密愈合,無法分離。這種結構有助于保護種子并適應風媒傳播。
常見示例
典型的穎果包括:
與其他果實的區别
詞源與發音
生物學意義
穎果的結構對禾本科植物的繁殖和人類農業至關重要,其高效的種子保護機制促進了谷類作物的廣泛種植。
注意:中文中“殼果”可能指堅果類,需結合語境區分,避免與“穎果”混淆。
