(…)其中，北方红栎树对铝浓度的增加最为敏感，在0.12 ~ 0.28 mM的铝浓度范围内，其根系生长受到抑制。Ca/Al比值对确定北方红橡树的毒性阈值尤为重要，当Ca/Al比值大于4时，未观察到铝的影响。在低离子强度溶液培养实验中，0.5 mM浓度的铝使欧洲山毛榉的茎部生长降低40%。
(...) Of the three species evaluated, northern red oak was the most sensitive to increasing Al, exhibiting root growth reductions at Al concentrations ranging from 0.12 to 0.28 mM in two separate experiments. The Ca/Al ratio was found to be particularly important in establishing toxicity thresholds for northern red oak with no Al impacts observed when Ca/Al ratio was greater than 4. In low ionic strength solution culture experiments, shoot growth of european beech was reduced by 40% at an Al concentration of 0.5 mM. (...)
