| 摘 要： | 以武香粳9号和武运粳7号为材料，研究了旱育苗床持续饱和水分对水稻秧苗体内物质代谢的影响。结果表明，与旱育秧苗相比，维持旱育苗床饱和水分9～12 h，可使植株硝态氮、叶片硝酸还原酶活性、地上部可溶性糖含量、根系可溶性蛋白、根系活力等物质代谢达到最优状态；随着苗床持续饱和水分时间的延长，叶片和根系中IAA和iPAs含

| Abstract: | Effects of sustainable water saturation in dry nursery seedbed （SSWS）on material metabolism of rice seedlings were studied by using the japonica varieties of Wuxiangjing 9 and Wuyunjing 7. The results showed that compared to dry seedbed seedlings, under keeping water saturation in dry nursery seed |
