Table 2 Effect of different salinity levels on the concentrations of Cl - , K + , Na + and the ratio of K + to Na + in apple roots inoculated and non-inoculated with Glomus versiforme

From: Arbuscular mycorrhizal fungi increase salt tolerance of apple seedlings

Treatment Non-inoculation Inoculation
  Cl-(g kg-1) K+(g kg-1) Na+(g kg-1) K+/Na+ Cl-(g kg-1) K+(g kg-1) Na+(g kg-1) K+/Na+

  1. aValues of each column followed by the same letter are not significantly different at the 0.05 level. Each value represents the mean of 6 replicates. Numerals 30, 60 and 90 stand for sampling times (days) after salinity treatment. The sign “×” denotes that apple plants were dead.
