In this work , the transgenic plants showed a tendency to accumulate less na + and more k + under saline condition than wild type plants and there was a high cytosolic k + / na + ratio in the roots of transgenic lines . 5 . x - ray microanalysis of na + , k + contents of the symplast and apoplast showed that transgenic lines accumulate less na + and more k + in the symplast than wild type plants 在对转基因植株及野生型植株用100nunol lnaci处理六天后， na ” 、 k ”的x一射线微区分析，转基因植株根、叶中质外体na 、 k十含量变化不大，但共质体中na十含量明显降低，广含量高于对照。
