In flooded soils, the rapid effects of decreasing oxygen availability on root metabolic activity are likely to generate many potential chemical signals that may impact on stomatal apertures. Detached leaf transpiration tests showed that filtered xylem sap, collected at realistic flow rates from plants flooded for 2 h and 4 h, contained one or more factors that reduced stomatal apertures. The cl...

Understanding the contributions of soil water evaporation (E) and crop transpiration (T) to evapotranspiration (ET) is essential for irrigation management improving use efficiency. Current methods partitioning ET are subject uncertainties, due in part scale differences determining E, T, ET. In this study, a lysimeter planted with maize (Zea mays L.) was partitioned into E T using sensors that h...
