Although the concentration of sodium in leaves of Atriplex plants increased rapidly after receiving sodium, no growth response was detectable for about 6 days. It was found that respiration rate increased to its maximum within 3 days. Chlorophyll content also increased from an early stage, whereas the concentrations of sugars and starch did not increase, and ratios of soluble to total nitrogen did not decrease until later.The respiratory response appears to be specific to sodium as different salts of sodium caused similar responses, and no other univalent cation substituted for sodium. In addition, both growth response and respiration rate tended towards their maxima with the same concentration of applied sodium. The rate of anaerobic CO(2) production increased when sodium was fed to leaves, suggesting that the effect of sodium is in the glycolytic sequence.
尽管经过钠处理后滨藜属植物叶片中的钠浓度迅速增加，但在大约 6 天内没有检测到生长反应。研究发现，呼吸速率在 3 天内增加到最大值。叶绿素含量也从早期开始增加，而糖和淀粉的浓度并没有增加，直到后来可溶性氮与总氮的比例才下降。呼吸反应似乎是针对钠的特异性反应，因为不同的钠盐引起类似的反应，而且没有其他单价阳离子替代钠。此外，随着施加的钠浓度相同，生长反应和呼吸速率都趋于最大值。当向叶片中添加钠时，厌氧 CO(2)的产生速率增加，这表明钠的作用是在糖酵解序列中。
