阳春砂是我国珍稀濒危的药用植物，以其果实入药。由于阳春砂柱头高于花药，自然传粉结实率低，严重制约了果实产量。为揭示阳春砂果实形成的基础，探讨提高阳春砂产量的对应策略，本文就阳春砂的形态特征、生态习性、花粉发育、胚囊发育及开花、传粉、受精等有性生殖研究状况进行综述。
暘春砂是我國珍稀瀕危的藥用植物，以其果實入藥。由于暘春砂柱頭高于花藥，自然傳粉結實率低，嚴重製約瞭果實產量。為揭示暘春砂果實形成的基礎，探討提高暘春砂產量的對應策略，本文就暘春砂的形態特徵、生態習性、花粉髮育、胚囊髮育及開花、傳粉、受精等有性生殖研究狀況進行綜述。

Amomum villosum is rare and endangered medicinal plants in China, its fruit is used as medicine. Natural pollination seed setting rate is low for stigma being higher than anther, which severely limits its fruit production. In order to reveal the basis of forming fruit and explore corresponding strategy of improving the yield of A. villosum, the paper summarized research status on sexual reproduction such as morphological characteristics, ecological characteristics, pollen development, embryo sac development, flowering, pollination and fertilization.
