| 摘 要： | 为选育抗旱性强、耗水少、水分利用效率高的品种.以22个玉米自交系为材料,采取正常灌溉和适度水分胁迫处理,对自交系叶片水分利用效率(WUE)、光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)、胞间CO2浓度(Ci)、相对叶绿素值( SPAD)和荧光动力学参数进行研究.结果表明,不同自交系WUE差异显著,而且对水分的敏...

| Abstract: | For the breeding of drought resistant,low water consumption,high water use efficiency of varieties,the water use efficiency(WUE) of leaf can affect the yield of crop directly.In order to determine the relationship between WUE and genetics background,and to elucidate the mechanism of that how WUE affect the yield,22 maize inbred lines were grown under water controlled condition.the following physiology index,water use efficiency of inbred lines leaf(WUE),photosynthetic rate(Pn),transpiration rate(Tr),stomata... |
