鸭跖草

Any plant of the genus Commelina.

鸭跖草属的任何一种植物。

Vascular bundles of the pedicel in flower of Commelina communis were scattered within central fundamental tissues.

鸭跖草花梗顶部的维管束分布在中央的基本组织内。

Objective:To determine six kinds of trace elements in Commelina communis Linn.and Schisandra chinensis Turcz..

目的：测定黑龙江省产鸭跖草及五味子中6种金属元素含量。

Result:The Ca content was rich in both herbs,and the Fe content was rich in Commelina communis Linn.

结果：两种中草药中Ca元素含量非常丰富，鸭跖草中Fe含量也很多。

The genetic similarity of three populations of Commelina communis grown in copper mine deposits, and two populations in noncontaminated soil was analysed using random amplified polymorphic DNA .

利用RAPD技术分析了不同空间地段上的鸭跖草种群（其中3个生长在铜矿山上，2个生长在正常土壤中）之间的遗传分化及多样性。

A hydroponical experiment was carried out to study the toxicity of copper, cadmium and their combined pollution on ultrastructure of Commelina bengalensis Linn. Transmission Electron Microscope was used to investigate the effect of heavy metal on ultrastructure of different parts of plants.

为了解铜、镉对泡泡草根、茎、叶细胞亚显微结构的毒害及作用位点，以期为进一步研究鸭跖草属植物的耐重金属机理提供理论基础，本文通过透射电子显微技术研究了75 μmol·L-1铜和50μml·L-1镉及其交互污染对泡泡草根、茎、叶细胞超微结构的影响和铜、镉在细胞中的分布。

Four primers screened from 17 primers were used to analyze genetic diversity between one population in the mine deposits and one in noncontaminated soil, the results showed that a higher level of DNA diversity was detected in the plants grown in the mine deposit. The results above indicated that Commelina communis grown in copper mine deposits had evolved adaptation under heavy metal stress, and such adaptation had a geneic basis.

从17条引物中筛选出4条对其中1个铜矿山种群和1个正常土壤种群进行种群内的遗传多样性研究，结果显示污染种群内基因遗传多样性水平高于未污染种群，上述结果说明了在铜胁迫下矿山鸭跖草种群已经进化了对铜污染的适应性，并且较高水平的遗传多样性可能是植物适应重金属污染胁迫环境的基础。

The effects of EDTA and various organic acids (formic acid, citric acid, malic acid, tartaric acid, and suriccine acid) on copper accumlation from solution to hyperaccumulator and non-accumulator subspecies of Commelina communis tissue was investigated in a 30-day pot experiment.

在实验中，研究了鸭跖草的超积累和非超积累植物在EDTA和多种低分子量有机酸（甲酸、苹果酸、柠檬酸、酒石酸和琥珀酸）的存在下，对植物组织从培养液中吸收和积累铜的影响。

Five dominant species including 〖WTBX〗Commelina communis,Elsholtzia haichowensis,Silene fortunei,Polygonum perfoliatum〖WTBZ〗 and 〖WTBX〗Kummerowia striata〖WTBZ〗 were found to have high concentration of total Cu,Pb,Zn,Cd,Cr.

结果表明，鸭跖草等5种植物对重金属Cu、Pb、Zn、Cd、Cr都有程度不等的高量积累，尤其是铜元素，其最高积累量出现在海洲香薷根部，达到844.65 mg/kg，是一般植物Cu含量（5~25 mg/kg）的33.8~1689倍；而在同样条件下，As在5种植物体内的含量为018~098 mg/kg，远远低于As在一般植物中的含量（＜10 mg/kg），这说明这些植物对As可能具有某种规避机制。

In particular,Cu had a high concentration in the root of 〖WTBX〗Elsholtzia haichowensis〖WTBZ〗,being at 84465 mg/kg,which is 338~1689 times higher than the general content in plants (5~25 mg/kg).

从植物对重金属的吸收、富集和转运能力综合考虑，鸭跖草等5种植物都不太可能是重金属Cu等6种重金属的超累积植物。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
