颖果棕褐色，长椭圆形，长约3毫米。
温度高不利于色稻颖果着色。
过高的气温不利于颖果着色，适度的低温能延长颖果的着色时间。
High temperature went against the accumulation of anthocyanidin and relatively low temperature extended accumulation duration.
富含胆碱的残留花药、雌蕊及早期颖果是禾谷镰孢菌的主要初侵染源；
Besides anthers at anthesis, pistils and young caryopses are rich in choline and are the main sites of the initial infection.
颖果的远胚端最早沉积花色素，以后逐渐延伸到胚端并使整个果皮着色；
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.
除果皮沉积花色素等色素外，有色稻颖果的生长、胚乳发育与常规水稻品种基本相同。
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.
同一亚种间，小粒品种发育时间短，大粒品种发育时间长，最终颖果干重大于小粒品种。
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;
比较了两个籼稻品种颖果的发育，籽粒的主要品质性状以及胚乳淀粉体的大小、形状、结构等特性。
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.
䅟属植物的颖果腹面形状、纹饰、表面小孔直径及平均密度等性状，可为种类鉴定及种间关系分析提供有价值的证据。
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.
