The electron microscopy and X-ray microanalysis revealed that there were no deposits of LREEs in the Casparian band of fern adventitious root.

用电子透射电镜观察和X-射线能谱分析植物的不定根的结果表明，并没有轻稀土元素沉积在植物根细胞的凯氏带上。

A comparison of photosynthetic rate, transpiration rate, w ater use efficiency, stomatal conductance, intercellular CO 2 concentration and vapor pressure deficit at the leaf surface between Poaceae C 4 plants (Chloris virgata and Setaria viridis) an d Chenopodiaceae C 3 plants (Chenopodium album and Chenopodium glaucum) under the simulated photosynthetic radiation was conducted in this st udy.

利用人工模拟光源研究了两种 C4 光合途径禾本科植物和两种 C3光合途径藜科植物的光合速率、蒸腾速率、水分利用率、气孔导度、胞间 CO2 浓度及叶面饱和蒸气压亏缺随模拟光辐射增强的变化规律及 Gs、Ci、Vpdl对 Tr和 WUE的影响。

The relationships between the analyzed processes of physiological ecology was circulative feedback.

植物生态场的时空分布规律使植物的近距离抑制作用和宏观生态效益和谐统一在共同的理论基础上。

In addition, the content of OlsenP of soil with plants was higher than that of soil without plantfor soils with Cynodon dactylon and Ficus tikoua by 215％ and 127％.Key words: Three Gorges Reservoir; WaterFluctuationZone; phosphorous release; effective factor

种植植物的土壤在淹水后OlsenP含量大于土壤直接淹没时的释放量，种植狗牙根和野地瓜藤的土壤中OlsenP分别较未种植物土壤释放量高出215％和127％。

We found that this lowered VOCs by a third," Fjeld says."A similar process helps plants to control humidity, helping to prevent coughs and sore throats.

我们发现植物的分解变化作用能使空气中的VOCs减少了三分之一，&Fjeld说，&另一个类似过程则是帮助植物来控制湿度，从而避免了咳嗽和咽喉疼痛症状的发生。

Some proposals for protecting the resource of the rare and endanged plants are put forward on basis of geographical distribution and floristic f...

阐述了这些植物的地理分布和区系特征，并根据该区珍稀濒危植物的现状提出了一些具体的保护措施。

According to Bract Scale and Seed Scale Complex theory and the observation results in this experiment, the author considers that the Gnetum genus belongs to the evolvement line ofBSSC. and is more closer to conifers than other seed plant.

根据苞鳞-种鳞复合体理论，结合本文的观察结果，作者认为买麻藤属植物是苞鳞-种鳞复合体演化线上的成员，与松杉类植物的关系比较近。

Internal transcribed sequences of ribosomal DNA of 36 species wereanalyzed to reconstruct the phologeny of Heracleum and its related genera using themaximum parsimony, neighboring-joint and maximum likelihood methods inPAUP4.0b10, respectively.

选取独活属7种植物测取核rDNA中的ITS基因序列，结合GenBank已有的本属5种和邻近属24种植物的ITS序列，用PAUP4.0b10软件中的最大简约法、邻接法和最大似然法分别进行分析，从而对独活属及其近属进行了系统发育重建。

As in Hanshiqiao nature reserve, the community coverage of invasive plants like Humulus scandens can even reach 90% or more, they may have formed a community with only one dominant plant, which makes it impossible for the native wetland plants like Phragmites communis to grow.

如汉石桥湿地保护区，捧草等入侵植物的群落盖度达到90％以上，有些形成单优势的群落，抑制了芦苇等湿地植物的生长。

After absorbs the solar radiating heat, hydrone from sea, rivers,lake, moist soil and other moist surface evaporation to atmosphere in;The growth in the surface plant, proliferates through stem leaf'sevaporating the water to the atmosphere in, plant's this kind ofevaporation usually is called the transpiration.

吸收太阳辐射热后，水分子从海洋、河流、湖泊、潮湿土壤和其他潮湿表面蒸发到大气中去；生长在地表的植物，通过茎叶的蒸发将水扩散到大气中，植物的这种蒸发作用通常又称为蒸腾。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
