【摘要】 以大豆耐铝基因型"吉林70"为材料,采用营养液培养的方法,研究了铝胁迫下~3H-ABA在大豆体内的运输与分布。实验结果表明,ABA能够在大豆幼苗体内快速运输和分配;铝胁迫可加快ABA在大豆体内的运输,并使ABA倾向于分配在受铝胁迫的根部。本研究将为阐明ABA在植物抗铝过程中的作用机制奠定基础。更多还原

【Abstract】 A hydroponic experiment combining radioisotope techniques was carried out to understand the effect of Al stress on the transport and the distribution of ~3H-ABA by using Jilin70,a soybean variety of Al resistance.The transport and distribution of ABA affected by Al stress on soybean seedling were studied with radioisotope technique.The results showed that ABA could be transported up or down in soybean seedling.The stress of Al accelerated the transport of ABA and enhanced the distribution of ABA in the roots by Al stress.The paper present the foundation for the mechanisms of ABA under Al stress in plant.更多还原
