金鱼藻

With static experiments, the authors investigated the biomass change of Ceratophyllum demersum and Microcystis aeruginosa cultured in Hoagland's solution with different concentration levels of Microcystis aeruginosa.

通过静态模拟实验，比较了单独培养和共生培养下，不同初始藻密度时金鱼藻生物量和铜绿微囊藻密度的变化。

As an extension to the "973" Program of National Planning key basic research project -----the study of China lake nutrient over-enrichment process and the mechanism of blue alga outbreak, this paper introduces our experiments as below:(1) Experiment on heavy metal absorption and disorption abilities of Ceratophyllum demersum , Hydrilla verticillata and Myriophyllum triphyllum, in order to campare their absorption capability .

本文在前人的研究基础上，依托国家&973&国家重点基础研究规划项目&湖泊富营养化过程与蓝藻水华暴发机理&，开展了下列工作： 1、选取狐尾藻、金鱼藻、黑藻三种大型沉水植物作为研究对象，通过对重金属离子铜离子的吸附及解吸实验，比较其三种沉水植物之间吸附能力的大小； 2、选取狐尾藻、黑藻为研究对象，研究了重金属离子铜离子对沉水植物的胁迫作用及铜离子在植物体内的富集情况； 3、选取黑藻为研究对象，研究了沉水植物在富营养条件下不同浓度的氨态氮和硝态氮对沉水植物的生理生长的影响。

The effects of different nutritional condition on the growth and antioxidant enzyme activity of submerged macrophytes Myriophyllum spicatum L, Hydrilla verticillata L and Ceratophyllum demersum L. were investigated in this study.

模拟研究了沉水植物狐尾藻Myriophyllum spicatum L、轮叶黑藻Hydrilla verticillata L和金鱼藻Ceratophyllum demersum L在中、富两种营养水平下的生长及生理特性。

The paper deals with Hg 2+?Cd 2+ and their interactions on chlorophyll a/b values, SOD activities and the contents of chlorophyll, soluble protein, free proline of Ceratophyllum demersum L.

研究了金鱼藻在不同浓度 Hg2 +、Cd2 +以及 Hg2 +、Cd2 +共同胁迫下叶绿素含量、叶绿素 a/b值、可溶性蛋白含量、SOD活性和游离脯氨酸含量等的变化。

The effects of external rare earth on growth and physiological of Chlorella ellipsoidea and Ceratophyllum demersum were studied. The results implicated that there were apparently negative linear interrelation between the concentrations of Sm, Y and the numbers of Chlorella ellipsoidea, which would best be described as polynomial interrelation at 2～40mg/L concentration range of Sm and 2～20 mg/L of Y. The LC〓 of Sm and Y was respectively 41. 36mg/L and 2. 57mg/L by statistics, which also indicated the toxicity of Y was greater than that of Sm.

外源稀土对小球藻及金鱼藻生长生理影响研究结果表明：(1)中稀土元素Sm和重稀土元素Y处理浓度与小球藻生长量之间存在明显的负线性相关关系；在稀土一定处理浓度范围（Sm为2～40mg/L，Y为2～20mg/L）内，小球藻生长量随培养时间的动态变化符合多项式相关关系；统计计算得Sm和Y对小球藻的半致死浓度LC〓分别为41.36mg/L和22.57mg/L，表明Y对小球藻的毒性大于Sm。

The contents of protein and chlorophyll of Hydrilla verticillata. L is lower, but those of Myriophyllum spicatum L and Ceratophyllum demersum L raised steadily in the same condition, which indicated that those two submerged macrophytes have the stronger tolerance for nutrition than Hydrilla verticillata L.

通过对3种沉水植物可溶性蛋白和叶绿素质量分数的分析发现，黑藻在中富两种营养水平下，质量分数较低且波动平稳，金鱼藻和狐尾藻可溶性蛋白和叶绿素质量分数持续升高，表明这两种沉水植物对水体中营养盐的耐受能力较黑藻强。

And Ceratophyllum demersum L.

和金鱼藻Ceratophyllum demersum L。

During the experimental conditions, the activitys of SOD, POD and MDA of Ceratophyllum demersum L changed greatly, and raised rapidly in the late of experiment, which indicated that those two submerged macrophytes got more nutrient stress than Myriophyllum spicatum L, and the nutritional stress-resistant ability of Myriophyllum spi-catum L was higher than those two submerged macrophytes in the medium nutritional condition.

在本试验条件下，黑藻生物量小，而金鱼藻SOD活性、POD活性和MDA质量分数变化幅度大，在试验后期急速上升，表明这两种沉水植物受到的营养盐胁迫较狐尾藻大，而狐尾藻在中营养水平下的耐营养盐胁迫能力较强。

Based on the adaptation experiment, Hydrilla verticillata Royle and Ceratophyllum demersum L.were chosen to study the purifying effect on polluted Qinhuai River water at the late development stage of submerged macrophytes.

本试验在适应性培养的基础上筛选出黑藻和金鱼藻两种沉水植物，以秦淮河河水为处理对象，进行沉水植物生长晚期净化污染河水的静态试验研究。

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
