对长江下游迄今为止发现的最古老的新石器时代遗址--河姆渡遗址、罗家角遗址进行了植物硅酸体分析，结果在两遗址出土的陶器碎片中发现了起源于水稻叶片运动细胞硅酸体。硅酸体的形状解析结果表明：来自两遗址的硅酸体断面形状大致相同，而在大小方面存在显著差异。利用硅酸体形状亚种判别函数进行判别，结果河姆渡遗址的稻为粳稻，罗家角遗址的稻为籼稻。研究结果表明两遗址的栽培稻群体具有不同系统特性，为长江下游的水稻系统演化及稻作起源研究提供了有意义的实证数据。

To study subspecies of rice ( o. satival. ) cultivated at the early stage of the NeolithicAge, the morphological characters of.plant opals of rice detected from the potsherds from the 3rd and 4thcultural layers of Hemudu and Luojiajiao sites, were analysed and compared. The results showed that theplant opals from Hemudu site were larger and thicker than those from Luojiajiao site. By the discriminantfunction, rice cultivated in Hemudu site was discriminated to japonica, and rice cultivated in Luojiajiaosite was discriminated to indica, implying that there are different subspeeific characteristics between ricepopulations of Hemudu and Luojiajiao sites.
