摘　　要：以优质早籼稻品种佳禾早占为对照,研究优质早籼稻新品种泉珍10号、佳辐占与漳佳占的库、源、流特性。结果表明,泉珍10号库容量大,填库能力强,冠层叶挺直,叶面积指数大,干物质积累总量大,开花后茎鞘干物质向穗部运转量大,对稻谷的贡献率大;佳辐占和漳佳占的库、源、流特性有许多相似之处;佳辐占与漳佳占的主要差异:佳辐占穗粒数少,千粒重较大;漳佳占正好相反。The sink, source and flow of high-quality early Indica rice varieties （i. e. , Quanzhen 10, Jiafuzhan and Zhangjiazhan） were studied using the high-quality early Indica rice variety, Jiahezaozhan, as control for comparison. The result showed that Quanzhen 10 was superior in sink capacity and sink-filling ability, with more erect leaves in the canopy, larger leaf area index, more accumulated total dried matters, more transported matters from the stem, sheath and leaves to the panicle after flowering, and larger grain contribution ratio. Jiafuzhan and Zhangjiazhan had many similar characteristics in sink, source and flow. They differed in the following aspects： Jiafuzhan had fewer spikelets per panicle and greater weight per 1000 grains than Zhangjiazhan.
