| 摘 要： | 以大豆耐铝基因型"吉林70"为材料,采用液体培养的方法研究了铝胁迫下大豆根系柠檬酸分泌规律。结果表明:铝胁迫可使大豆根系分泌柠檬酸以抵抗铝的毒害,且柠檬酸的大量分泌是在铝胁迫6 h之后,说明其分泌方式应属于模式Ⅱ;分根试验表明,在同一株大豆幼苗中,铝只毒害与其接触的根,而对其他根基本不产生毒害。 |

| Abstract: | Aluminum toxicity is one of the most significant factors inhibiting plant growth and crop production in acid soils.The root growth is hurt by Al stress and absorbability of water and nutrient decreased,so the growth and development of plant are inhibited.In the present study,with solution culture,Jilin 70 was selected as the Al-tolerant cultivars for the research of effect of Al on the citrate secretion of soybean seedling.The results were as follows: Exclusion of citrate acid from soybean roots could be us... |
| Keywords: | soybean Al toxicity citric acid secretion |
