During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

The pattern of aerenchyma formation could originate by the combination of cortical cell autolysis and enlarged intercellular space. The process occurred in some stages: cortical cells stopped expansion and the intercellular space became larger at the initial stage. Cortical cells to collapse and autolysis were found with the disintegration of cell contents. After the evacuation of cell contents, cortical cells became shrinking and invaginated.
形成过程大体分为:皮层细胞生长停止,细胞间隙增大;皮层细胞衰老,并发生自溶,内含物解体;解体物逐渐撤走,皮层细胞开始收缩、内陷,当细胞内含物全部撤走,相邻细胞的残留细胞壁叠合即在两侧形成通气空腔;径向上相邻的皮层细胞逐步发生凹陷和细胞壁叠合,结合方形的细胞间隙一起构成通气组织。
