- Abstract:
-
The Lolium multiflorum seeds were treated with different Al concentrations so as to study the influence of Al stress on their seed germination and seedling growth. The results showed that medium (10~50 mg/L) Al concentration exerted little influence on the seed germination index and germination percentage (p<0.05), however, when the concentration of Al in the range of 100~500 mg/L, the seed germination index and germination percentage significantly decreased (p0.05) compared with those controls. Medium (10~500 mg/L) Al concentration significantly inhibited the plant height growth and root elongation (p<0.05), and the inhibition was increased with the Al concentrations. When the concentration of Al in the range of 100~500 mg/L, no roots were found. In addition, medium Al concentration significantly influenced the membrane permeability, the medium Al concentration (10 mg/L) obviously decreased it in the 7th day and the 13th day under Al stress (p<0.05), but medium (50~500 mg/L) Al concentration obviously increased it (p<0.05).
