Compared with nacl treatment , under na2co3 stress , the organic osmotica played a more important role in osmotic regulation of suaeda salsa which maybe resulted from the adaptive reaction to high ph value 和nacl处理相比，在na _ 2co _ 3胁迫下，有机物所起的渗透调节作用大于nacl处理，这也许是碱蓬为适应高ph环境而作出适应性反应的结果。
Thus help the seedlings survive better in the flooding and saline conditions . the density of mature hypocotyls of b . gymnorrhiza was close to or lower than seawater , thus the propagules can float and be dispersed by tide 并通过主动的渗透调节，控制各种渗透调节剂和水分的输入，使得成熟胚轴的渗透势达到比生境中略低的一个比较合适的水平。
The osmotic adjustment ability of salicornia bigelovii torr . was 1 . 12mpa under 100mmol / lnacl , while osmotic adjustment ability of zea mays was only 0 . 61mpa . 6 . the effects of salt - treament on the ultrastructure of chloroplast of salicornia bigelovii torr 100mmol / lnaci处理时，海蓬子地上部细胞汁液的渗透调节能力为1 . 12mpa ，而相同盐度处理时玉米的渗透调节能力仅为o . 6lmpa 。
The maladies caused by salt stress arise from the disruption of cellular aqueous and ionic equilibrium . na + accumulates excessively in the cytoplasm can be toxic to the metabolism and affects the regulation mechanism of the plant cell 盐胁迫条件下，植物细胞渗透均衡和离子正常均衡状态被破坏，特别是胞质中过多的na ~ +渗透调节对植物细胞的新陈代谢产生毒害，影响到植物细胞的调节机制。
Under middle level drought condition mosuchun can increase content of soluble organic osmoticum ( pro , amino add and sugars ) maintain or raise the activity of sod and cat , and decrease permeability of plasma and content of mda 在干旱条件下摩素淳能增加游离氨基酸、可溶性糖和脯氨酸3种有机渗透调节物质的含量，维持或提高sod和cat活性，降低膜相对透性和mda含量，防止或降低了膜脂过氧化作用对膜的伤害。
Acquiring the novel drought resistance genes with knowledge property right became very important to our country . the research demonstrated that plant could adapt water stress through signal transduction , osmotic adjustment , desiccation protection and metabolic changes 研究表明，植物能够通过信号传递、渗透调节、代谢调整、脱水保护等多种机制适应干旱胁迫，与其相关的基因相继被克隆应用于生产实践。
