以进境转基因大豆中截获的豚草种子为材料,通过热水浸泡、浓硫酸处理、双氧水浸泡、高锰酸钾浸泡、赤霉素浸泡、低温处理、去除种皮等方法,研究了不同处理对截获休眠豚草种子萌发的影响。结果表明:300mg/LGA、3.0%H2O2、3～5℃低温沙藏3个月、4个月和去种壳处理对休眠中的豚草种子有一定的刺激作用,但对豚草种子发芽率影响不太明显;3～5℃低温沙藏5个月可使豚草种子发芽率提高至10%。
The ragweed seeds intercepted in the transgenic soybean were used as materials to study the effects of different treatments on the ragweed seeds, such as hot water immersion, concentrated sulfuric acid treatment, hydrogen peroxide immersion, potassium permanganate soaking, gibberellin soaking, low temperature treatment, Effects of intercepting ragweed seeds on germination. The results showed that: 300mg / LGA, 3.0% H2O2, 3 ~ 5 ℃ low temperature sand reservoir for 3 months, 4 months and seed-shelled treatment had some stimulating effects on the ragweed seed during dormancy, The effect is not obvious; the germination rate of ragweed seeds can be increased to 10% at 5 ~ 5 ℃ for 5 months.
