盐生植物

The purpose of this study isto observe the seed germination in different salt solutions ,the growth of the seedling underthe salt stress and recovery growth. It can provide some theory evidence for the developmentof halophyte resource.

本研究的目的就是研究盐地碱蓬在不同盐胁迫下种子萌发、幼苗生长及胁迫解除后的生长情况，为盐生植物资源的开发利用提供理论依据。

The results showed that K.sieversiana could grow under high salt-alkaline conditions even when the salinity reached 500mmol and pH10.51. It was proved that K.sieversiana was a halophyte species with great tolerance to salinity and alkalinity.

结果表明：碱地肤幼苗在盐度为500mmol，pH10.51的高盐高碱条件下还能生长，证明了它是既高度耐盐又高度抗碱的盐生植物。

The leakage of K+, the peroxidation of lipids and the disruption of membranes induced by NaCl were different between halophytes and xerophyte.

NaCl诱导盐生植物和旱生植物种子K~+外渗、膜完整性破坏和膜脂过氧化反应表现不同。

The effect of NaCl on seed germination was due to both osmotic stress and ion toxicity for both halophytes, e.g., Suaeda physophora and Haloxylon ammodendron, and xerophyte, e.g., Haloxylon persicum.

NaCl对盐生植物(梭梭Haloxylon ammodendron；囊果碱蓬Suaeda physophora)和旱生植物(白梭梭Haloxylon persicum)种子萌发既有离子伤害又有渗透胁迫。

The results showed that the two species were both very salt-tolerant plants and Halostachys caspica was more salt-tolerant than Kalidium foliatum.

盐爪爪和盐穗木是两种非常耐盐的藜科盐生植物，在新疆盐碱地广布。

The above results show that Phragmites communis,might be a pseudohalophyte.

上述结果证明芦苇是一种应性较强的植物，从抗盐机理考虑可以认为它是一种假盐生植物。

Suaeda salsa is a leaf succulent euhalophyte that may have evolved the unique salt-tolerant mechanism.

盐地碱蓬是一种叶肉质化的稀盐盐生植物，在进化中可能形成了特殊耐盐机制。

These results suggested that higher concentration of NaCl could cause the seed dormancy and accelerate the germination of ungerminated seeds. Perhaps there was a mechanism that the seed coat or embryo could prevent Na~+ from entering into the embryo so as to keep higher K~+ and lower Na~+/K~+ in the embryo. And it might be one of the physical mechanisms that the seed of Hibiscus hamabo Sieb.et Zucc. could resist high salinity stress. In addition, the annual seedlings of Hibiscus hamabo Sieb.et Zucc.

上述结果表明：高浓度的盐可以诱导海滨木槿种子休眠并促进盐胁迫解除后种子的萌发，这种机制可以使之避开不良的萌发条件，等到降雨使土壤溶液浓度降低再萌发，这是盐生植物的种子适应盐渍生境的一种有效方式；海滨木槿的种皮有阻挡Na~+进入胚的作用或胚具有某种拒Na~+的机制，使胚保持较高含量的K~+和较低的Na~+/K~+，这可能是海滨木槿种子耐盐的主要生理原因之一。

The objective of this paper was to discuss the main types and construction strategies of cDNA and its application to halophytes and salt-tolerant mechanism of halophytes were suggested.

旨在对cDNA文库的主要类型及其构建策略，以及cDNA文库在盐生植物新基因筛选中的应用进行综合论述，并对植物耐盐机制的研究提出了展望。

Thus, a set of methods were established for reliable protein extraction and 2-DE analysis for salt-tolerant plants, particularly woody halophytes.

该结果为盐生植物，尤其是盐生木本植物，建立了一套可靠的蛋白提取和双向电泳方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
