Under the stress of nacl lower than 100 mmol / l , the tissue structure of root had no distinct difference from the control . when the concentration of nacl was higher than 250 mmol / l , the stained color of safranine was deep but not even , and color in fibrovascular tissue and peripheral cortex cell were deeper than that around fibrovascular tissue . wild type arabidopsis thaliana and two salt - tolerance mutants were used for rapd analysis 当nacl浓度小于100mmol l时，根组织结构与对照未表现出明显的差异；但当nacl浓度达到250mmol l时，根组织结构对番红染料的着色较深而且不均匀，维管组织和外围皮层细胞着色较深，而维管组织周围的细胞着色较浅。
