Abstract
Effects of manganese(Mn)toxicity on plant growth,chlorophyll concentration,acquisition of iron(Fe)and magnesium(Mg)in Stylosanthes guianensis(Stylo)seedling were investigated in the nutrient solution experiments.The results showed that the typical symptoms of Mn toxicity in stylo were indicated by leaf chlorosis and crinkle.Plant growth and chlorophyll concentration in leaves were obviously decreased at 200 UmoL/L Mn application.With the increase of Mn availability,content of Mn and Fe was significantly increased in both shoots and roots.However,Mg content in roots was decreased,but in shoots was not affected.All the results showed that maintaining Mg homeostasis and relative high level of Fe in shoots might be one of adaptive mechanisms of stylo to Mn toxicity.
