| 摘 要： | 选用5个玉米杂交种为试材,探讨了苗期生长发育和水分利用效率的关系。结果表明,GWUE、产量和耗水量在品种间的差异显著,在3种供水条件下,郑单958是高GWUE品种,具有高产中耗水的特性,鲁单981是低GWUE的品种,是低产高耗水品种,而四单19的GWUE是在干旱胁迫下最具增长潜力的品种,具有稳产节水的特性。

| Abstract: | Using five maize varieties as materials, the relationship between water use efficiency and growing development of seeding were studied. The results showed that water use efficiency, biomass and water consumption of 5 varieties existed obvious diversity, under three water conditions GWUE variety of Zhengdan958 was higher, it had the characteristics of high water consumption, and Ludan981 had lower yield and high water consumption variety, but Sidanl9 had the most growth potential in the varieties under drought stress, had the characteristics of stable production and water-saving. |
