摘要
实验用不同浓度镧液处理大豆种子,研究镧对大豆种子萌发的影响。结果表明:低浓度的镧对大豆种子的萌发有明显的促进作用,其中以5m l/L为优;高浓度的镧对大豆种子的萌发有抑制作用,甚至有毒害作用。
This experiment studies the influence of the rare metal La on the germination of soybean seeds with La liquids of different concentration.The experiment shows that low-concentration La liquid(especially 5ml/L) apparently promotes the germination,while high-concentration La liquid restrains the germination and even has poisonous effects.
