【摘要】 <正>O₂ deficiency（hypoxia-anoxia）is one of the key determinants influencing root growth and functioning during waterlogging.Hypoxia-anoxia induced changes in net K⁺ flux and membrane potential across the plasma membrane of root cells were measured in elongation and mature zones of roots of two barley varieties contrasting in their waterlogging tolerance（tolerant variety CM72 and sensitive variety Naso Nijo）using the non-invasive更多还原
