盐生植物

Recently, Thellungiella halophila, a close-relative ofArabidopsis thaliana, which is been suggested and be developed as a new salttolerance model plant. Thellungiella halophila is a salt-tolerance crucifer with a shortlife cycle, small genome, and with high sequence similarity(about 90-95% on cDNAlevel), similar heredity characteristics and growth habits with Arabidopsis thaliana.So it is convenience for T. halophila to benefit from a lot of Arabidopsis thalianainformation data.

最近，另一个盐生植物盐芥被提议为研究植物耐盐性的模式系统，它是拟南芥的近缘，为生长周期短、基因组较小、耐盐性较强的十字花科的盐生植物；在cDNA水平上与拟南芥有大约90-95％的同源性，因此，可以方便地将拟南芥的很多信息移至盐芥耐盐性的分子生物学研究；而且，盐芥具有拟南芥很多同样的优点以作为实验系统。

But K+ content in every organ of A.commans persicoides rootstocks was higher than that of other two almond rootstocks;the ratio of Na+/K+ in Amygdalus communis L.was higher than that of other two rootstocks.

盐逆境下植物器官之间Na+的区域化分配往往决定着植物整体水平的耐盐能力，Greenway和Munns提出，非盐生植物通过在根部贮存较多的Na+，以阻止Na+在地上部积累，有利于增强植物的耐盐性[1]。

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.

区系中的单细胞浮游藻类包括近岸广布种116种、近岸暖水种31种、近岸温带种26种；维管束植物被划分为6大生态类群，包括盐生植物24种、水生植物22种、湿生植物35种、中生植物103种、旱生植物6种、沙生植物4种，保护区内湿地植被的建群种、优势种均为水生植物、湿生植物或盐生植物，反映了湿地植被的隐域性；维管束植物按照生活型划分，有20种高位芽植物、4种地上芽植物、54种地面芽植物、48种地下芽植物和68种1年生植物，其中地面芽植物、地下芽植物占区系植物总种数的比例较高，占52.58%，反映冷湿气候和局部低洼积水环境对区系的形成起较重要作用。

In this paper, the bio-ecological characteristics of indigenous halophytes: Salsola implicata, Suaeda linifolia, Halocnemum strobilaceum and Kalidium foliatum will be studied in order to explore the mechanisms of plants tolerance and to get the theory and measures for treating salt soil and applying halophytes.

本文拟通过对生长于盐渍化土地上的四种常见盐生植物：盐爪爪、盐节木、亚麻叶碱蓬和密枝猪毛菜的生物生态学特性的研究，查明盐生植物适应盐渍化土壤的机制，为在盐渍化土地上恢复、重建和扩展植被，并为改造该类土地提供依据。

The results of observation on the microstructure of Karelinia caspica, Tamarix stromongolica, Salsola collina. Cheno Dodium glaucum, stipa bangenana show that the nutritional organs of these halophytes present some adaptability structures as follows:(1) sunken stomas, thick cuticle and orderly arrangement of epidermal cell;(2) equilateral leaves with developed palisade tissue, or squama-shaped leaf;(3) well-developed water-storing tissue in stems and leaves;(4) crystal cells, salt glands in most of the leaves and assimilating branches.

The problem of plant's tolerance to salt is mainly the tolerance to NaCl. The research is mainly focused on two aspects: First, the study of salt-tolerance physiology in halophytes; second, the study of the injurious physiology in nonhalophytes. Thereby we can understand how to ameliorate or increase the plants'salt-resistance.

植物的耐盐问题，主要是指植物对NaCl的耐性问题，植物耐盐生理的研究，主要从两个方面入手：一是研究盐生植物对盐度的耐性生理；二是研究盐度对非盐生植物的盐害生理，从而了解改善和提高植物抗盐能力。

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