水稻种子生产这在很大程度上取决于花的数量，而花的数量又受花序结构的调节。禾本科植物（包括水稻）的花序和小穗的发育过程与其它单子叶和双子叶植物有很大的不同，而水稻是一种重要的农作物，常被用作单子叶植物的模式植物。然而，野生型水稻的发育过程尚未得到很好的表征。因此，详细描述水稻花序和小穗发育将是有价值的突变体的表型特征，也为比较水稻与其他禾本科植物。在本研究中，我们发现了花序和小穗发育过程中的一些标志性事件，并将它们的发育分别划分为9个和8个阶段。该分期系统可作为发育描述的参考。
Seed production in rice (Oryza sativa L.) largely depends on the number of flowers, which is in turn regulated by the inflorescence architecture. The developmental process of inflorescence and spikelet in grasses including rice differs considerably from that in other monocotyledonous and dicotyledonous species, and rice, an important crop plant, is often used as a model monocot plant. Nevertheless, the developmental course of wild-type rice has not yet been well characterized. Thus, detailed description of rice inflorescence and spikelet development would be valuable for characterizing mutant phenotypes and also for comparing rice with other grass species. In this study, we showed a number of landmark events in the developmental courses of inflorescence and spikelet, and divided their development into nine and eight stages, respectively. This staging system would be useful as a reference for developmental description.
