摘要:
以多花黑麦草为试材，通过水培试验，研究铝浓度对黑麦草种子萌发及其幼苗生长的影响。结果表明：（1）10～50 mg/L铝浓度对黑麦草种子发芽指数和发芽率无显著影响（p>0.05），而铝浓度介于100～500 mg/L时，与对照相比，黑麦草种子发芽指数和发芽率显著降低（p<0.05）；（2）铝浓度介于10～500 mg/L时，显著抑制黑麦草幼苗株高及其根的生长（p<0.05），且随着铝浓度的增加抑制作用越强，当铝浓度介于100～500 mg/L时，黑麦草根系停止生长；（3）铝浓度显著影响了黑麦草的质膜透性，与对照相比，10 mg/L铝浓度显著降低了其质膜透性（p<0.05）；而50～500 mg/L铝浓度则使黑麦草质膜透性显著增加（p<0.05）。
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).
