Abstract
Na + and K + contents were determined by atomic absorption spectrometry (Hitachi Z-8000) and plasmalemma vesicles as well as tonoplast vesicles were prepared by discontinuous sucrose gradient centrifugation.Under gradually increasing NaCl concentration treatments and NaCl shock treatments, both S K,Na(uptake)and S K,Na(transport)of salt-tolerant cultivar Dk961 were higher than those of salt-sensitive cultivar Lu15 (Fig.1). Root Na + content of Dk961 and root-stem junction Na + content of Lu15 increased continuously and showed accumulative effect (Fig.2). Root plasmalemma and tonoplast H +-ATPase activity of Dk961 were all obviously higher than those of Lu15 (Figs.3A, 4A). Tonoplast H +-ATPase activity of the root-stem junctions of Lu15 was higher than that of Dk961 (Fig.4B). For the same cultivar, plasmalemma and tonoplast H +-ATPase activity of the roots and root-stem junctions after NaCl shock treatment were lower than those after gradual increasing NaCl concentration treatment (Figs.3, 4).
