摘要
采用预冷、细沙和砂纸摩擦、热水和浓硫酸浸种共4种处理方法进行破除黄花棘豆种子休眠试验,结果表明,4种处理均可显著提高黄花棘豆种子的发芽率,其中砂纸摩擦方法简单、效果最佳,其发芽势和发芽率分别从8.2%和10.7%提高到51.9%和58.6%。
The experiment about breaking seed dormancy of Oxytropis ochrocephala Bunge by four treatments （pre-cooling, friction with sand and sandpaper, dipping in hot water and eroding with 98%H2SO4） was studied .The results showed that the four treatments all could improve its germinating percentage, especially the treatment with sandpaper friction which increased germinating percentage and germinating energy from 10.7% to 58.6%, 8.2% to 51.9% respectively.
