用氢氧化钠、浓硫酸、赤霉素分别对厚朴种子浸种处理,研究不同处理方法对厚朴种子萌发的影响。结果表明,用40%NaOH对厚朴种子浸种4 h,在30℃下催芽效果最好,可使种子发芽率和发芽势分别提高到92.0%和54.7%。
The seeds of Magnolia officinalis were soaked with sodium hydroxide, concentrated sulfuric acid and gibberellic acid respectively to study the effects of different treatments on the seed germination of Magnolia officinalis. The results showed that soaking the seed of Magnolia bark with 40% NaOH for 4 h resulted in the best germination rate at 30 ℃, which increased the seed germination rate and germination energy to 92.0% and 54.7% respectively.
