盐生植物

In this study, BADH, gene encoding the key enzyme in betaine biosynthesis, which was isolated from Atriplex hortensis, and SeNHX1, a vacuole Na+/H+ anitiporter in Salicornia europhaea L., were used to transform the tobacco to improve the salt tolerance.

本研究拟用耐盐性较强植物山菠菜中的甜菜碱合成关键基因BADH和盐生植物盐角草的液泡膜Na+/H+ anitiporter基因SeNHX1对模式植物烟草进行转化，以确定其各自在耐盐性方面所起的作用。

That indicated there was essential difference between the response of halophyte and nonhalophyte to salinty.

说明盐生植物与非盐生植物对盐度的响应有本质的区别。

Species of halophytic seeds and 2 species of non-halophytic seeds were treated with the different concentration of NaCl and iso-osmotic PEG.

用NaCl和等渗PEG处理 8种盐生植物和 2种非盐生植物种子。

The recent discovery of the halophytic plant species,Thellungiella halophila,which is native to the seashore saline soils,meets all the criteria for being a genetic model system.

而最近的研究发现，盐生植物—盐芥是研究植物耐盐机制最合适的植物。

The ordernance of15 species of main halophytic plant was make out according the contant of chemical elements,and the corresponding types of halophytic community was classified,the featues of its chemical element was analised.

据15种占优势的盐生植物元素化学成分含量高低顺序，按元素化学成分，对它们进行排序，划分了盐生植物群落类型和该区盐生植被的元素化学特征。

Halophytic seeds ; non-halophytic seeds ; seeds ; germination rate ; Na + and K + content ;α-amylase activity ; SOD activity

盐生植物；非盐生植物；种子；萌发率； Na+和K+的含量；α-淀粉酶； SOD

High salinity and temperature induce seeds of euhalophytes Halostachys caspica, Kalidium foliatum and Halocnemum strobilaceum to remain ungerminated, and seeds germination and seedling establishment of the three halophytic species can be ensured only when temperature and edaphic conditions are favorable. This is most likely an important adaptive strategy in these halophytic species to survive their saline environment in an arid region in Xinjiang;(2) morphological adaptations.

三种真盐生植物盐穗木、盐爪爪和盐节木种子在高盐和高温时不萌发，只有当温度和盐分适宦时种子才萌发，有利于幼苗的成活，是这三种植物适应新疆极端生境的策略。

Lastly,several key problems remaining to be solved in future researches into seed germination of halophytes,as well as...

最后 ，作者提出了将来研究盐生植物种子萌发需要解决的几个重点问题以及研究盐生植物种子休眠和萌发问题的意义

In order to elucidate the mechanism of salt-resistant structure , stems and leaves of 10 species of halophytes in the coast zone of Red Sea were studied by paraffin slice and light microscopy.

为阐明盐生植物的抗盐结构机理，采用石蜡制片和光学显微镜技术对埃及红海地区十种盐生植物的茎和叶进行了结构植物学研究。

The character of salt tolerant structure in halophytes has been summarized in three aspects: roots, stems and leaves, so that more materials about microcosmic structure could be provided for the study of the halophytes.

从根、茎、叶三方面总结了盐生植物的耐盐结构特点，旨在为盐生植物的研究提供更多的植物体微观结构资料。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
