金魚藻 的英文怎麼說
中文拼音 [jīnyúzǎo]
金魚藻
英文
ceratophyllum demersum-
The leaves and stems of c. demersum l. may contain 137. 8mg / kg ( dry weight ) of copper, so it can be served as hyperaccumulators of copper
金魚藻體內富集的銅含量達到137 . 8mg kg （干基） ，符合超級銅積累植物的標準。In bryophytes ( mosses, liverworts and horworts ) the haploid gametophyte is the dominant phase of the life cycle and the sporophyte is represented only by the capsule, seta, and foot
在苔蘚類植物中（苔蘚，地錢，金魚藻）單倍的配子體占生活史的主要部分，孢子體包括孢蒴、蒴柄和基足。The algae - eaters are colorful yellow tang and goldring surgeonfish, a species found only around the hawaiian islands
吃海藻的魚是炫麗的黃刺尾魚和金環刺尾魚，這種魚只在夏威夷群島附近發現過。The results showed : ( 1 ) the activity concentration of 95zr in water reduced quickly for subsidence, soil absorption, crucian intake, hornwort ' s absorption and adsorption. the dynamics of its disappearance accorded with binomial index regression law : cw. = 43. 36e - 1. 74t ' + 12. 85e - 0. 15 ( 2 ) the hornwort had stro
結果表明: （ l ）從水體中引入的95zr由於沉降、土壤吸附、被魚體攝入和金魚藻的吸收、吸附作用使水體中的gszr比活度呈快速下降，其消失動態符合二項指數衰減規律， cw = 43 . 36e . ， . 74t + 12 . 85e一住『 」 。We suspected that c. demersum l. was inadequate used as a single bioaccumulator. while c. caroliniana a. could tolerate the higher lever of cu2 +, it is advised to be a better selection to phytoremediation. when the two submerge macrophytes were planted together in cu2 + solution, the respective bcf of copper in two plants increased and the toleration of c. demersum l. was enhanced slightly
水盾草體內富集的銅含量可以達到61 . 0mg kg ；金魚藻對銅離子的耐性很低，且葉片受到銅脅迫時容易脫落，不適合作為銅濃度高的水體的生物修復植物，水盾草對銅離子的耐性較高，適合應用於含銅水體的生物修復；金魚藻和水盾草共同培養時，植物體內對銅的積累量有所增加，金魚藻對銅的耐性也略有提高。Changes of cell membrance lipid peroxidation and activities of antioxidant enzyme systems of ceratophyllum demersum l. in combinative pollution of cd2 and hg
復合污染下金魚藻的細胞膜脂過氧化和抗氧化酶活性的變化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。For the acute exposure duration, there expressed the dose - thresholds and time - thresholds in the effects of cu2 + on the activities of cat, pod and sod in two macrophytes. when the test species were exposed at low dose and for a short period, cu2 + can stimulate activities of antioxidant enzymes. once exceeding the thresholds, cu2 + may inhibit enzymes activities
Cu ~ （ 2 + ）低濃度和短時間內對抗氧化酶有誘導作用，超過一定的閾限會產生抑制作用；金魚藻cat 、 pod 、 sod活性在7天內的最大抑制率與暴露cu ~ （ 2 + ）濃度呈顯著正相關。Wwf kicked off the oceans 10 programme last year to raise public awareness on our marine environment by highlighting 10 marine species found in hong kong waters. these include brain coral, chinese bahaba, chinese white dolphin, green turtle, horseshoe crab, hong kong grouper, mudskipper, seagrass, purple sea urchin and yellow croaker. through a standalone website at
