Seagrass is the only flowering plant surviving wholly submerged in marine waters
海草是唯一完全淹沒在海水中仍能生存的有花植物。 -
Physiological changes of the submerged plant - vallisneria spiralis under organic solvents stress
有機溶劑脅迫下苦草生理指標的變化 -
In the field of the phytoremediation of copper pollution, submerged macrophytes are focused less than the terrestrial plants. in this study, ceratophyllum demersum l. and cahomba caroliniana a. gray were used as the test plant. the following two aspects were investigated in vivo methods : 1 ) the toxicity effects of cu2 + on the three main antioxidant enzymes ( including cat, pod and sod ) of two submerged macrophytes were detected at different low doses and on the chronic exposure, in order to establish the dose - effect relationship and the time - effect relationship, and thereby acquire the toxicity threshold ; and 2 ) with two submerge macrophytes throng cultured individual or combined on the chronic exposure, it was found on the bcf of copper and the influence of interspecific relationships to the submerge macrophytes resistance or bioconcentration
本論文以兩種大型沉水植物金魚藻（ c . demersuml . ）和水盾草（ c . carolinianaa . ）為受試植物，從它們對水體中cu ~ （ 2 + ）的生物富集作用和動態，以及cu ~ （ 2 + ）對它們體內抗氧化酶的急性毒性效應和亞急性毒性效應兩方面進行了研究： 1 ）通過體內暴露不同劑量的cu ~ （ 2 + ） ，探討cu ~ （ 2 + ）對植物體內三種主要的抗氧化物酶（ sod ， pod ， cat ）的毒理效應，建立劑量?效應關系和時間?效應關系，以揭示沉水植物對cu ~ （ 2 + ）的抗性機制； 2 ）通過對金魚藻，水盾草單獨培養和共同培養的方式，分別研究了兩種沉水植物對cu ~ （ 2 + ）的生物富集系數及其動態以及兩種植物的種間關系對富集銅和植物耐性的影響，綜合評價了兩種植物在銅污染水體的植物修復中的應用前景。 -
In this study the main form of the nitrogen that diffused from sediment into overly water was ammonia, and the submerged plant decreased the diffusion fluxes of ammonia and nitrate at water - sediment interface
總之，水沉積物界面氨氮是沉積物向上覆水擴散的主要氮組分，沉水植物降低了氨氮和硝態氮的擴散通量。 -
Special emphasis was put on the plant ' s suitability with its submerged life in seawater, especially its adaptation to the salinity of seawater
其中著重討論了大葉藻與海洋沉水生活相適應的一些特點，特別是其對海水鹽度的適應機理。 -
The effects of submerged plant on the concentrations of different nitrogen species in overlying water, porewater and sediment of different layers from water - sediment interface were investigated in simulating condition
摘要在室內模擬條件下研究沉水植物對水沉積物界面的上覆水、不同層次的間隙水和沉積物中不同形態氮含量的影響。 -
The results indicated that on average the rank order of the concentrations of different nitrogen species in overlying water and porewater was organic nitrogen > ammonia > nitrate ; the main form of inorganic nitrogen in sediments was of ammonia, and the submerged plant cannot change this case
結果表明：總體上，上覆水和間隙水中不同形態氮含量的順序為有機氮氨氮硝態氮；沉積物中可交換態無機氮以氨氮為主，沉水植物的存在並沒有改變這一格局。
