查询词典 vascular plants

It is nowhere muddy,and a casual observer would say that there were no weeds at all in it; and of noticeable plants, except in the little meadows recently overflowed, which do not properly belong to it, a closer scrutiny does not detect a flag nor a bulrush, nor even a lily, yellow or white, but only a few small heart-leaves and potamogetons, and perhaps a water-target or two; all which however a bather might not perceive; and these plants are clean and bright like the element they grow in.

它没有一处是泥泞的，偶尔观察的过客或许还会说，它里面连水草也没有一根；至于可以见到的水草，除了最近给上涨了的水淹没的、并不属于这个湖的草地以外，便是细心地查看也确实是看不到菖蒲和芦苇的，甚至没有水莲花，无论是黄色的或是白色的，最多只有一些心形叶子和河蓼草，也许还有一两张眼子菜；然而，游泳者也看不到它们；便是这些水草，也像它们生长在里面的水一样的明亮而无垢。

They resemble true plants in many ways and are thought to be the most closely related algal group to plants.

本纲中的生物在许多方面和真正的植物相似，被认为是最靠近植物的藻类生物类群。

Systematical variations of silica contents and silicon isotope compo- sitions are observed from their roots to stem to leaves, which provide us reliable evidences for studying the mechanisms of adsorption, transpor- tation and precipitation of silicon in plants, as well as the role of plants in silicon biogeochemical cycle.

由根往茎叶，硅的含量与同位素组成呈规律性变化。为研究植物中硅的吸收、搬运与沉淀机制，探讨植物在硅的生物地球化学循环中的作用提供依据。

We have constructed a bivalence expression vector with SsNHX1 and AVP1 and transformed them into Arabidopsis. The results showed that the transgenic Arabidopsis plants 101 and 127 grew much better than wild type plants in the medium containing 100 and 200 mmol/L NaCl, which further indicated the important roles of Na〓 compartmentalization in vacuoles on plant salt tolerance.

2构建了同时含有液泡膜Na〓/H〓 antiporter与H〓-PPase基因的双元植物表达载体并转入拟南芥，筛选到在100和200mMol/LNaCl胁迫环境下生长发育均明显好于野生型的转基因拟南芥植株101和127，进一步验证了液泡Na〓区隔化在植物耐盐方面的重要作用。

The floristic components have character as following: geographic -al elements of species is relatively simple;there are more species of world distributi -on and tropical genera,and there have world blazon predestined relationship and tropical predestined relationship.Composite,standing grain,legumina have absolutely predominance make of the backbone of floristic.Seed plants are mainly made up of herbage plants.

种子植物区系成分具有以下特点：种的地理成分相对简单；表现出明显的亚热带特征，并具有热带向温带过渡的特点；菊科、禾本科、豆科占有绝对优势，构成植物区系的骨干；种子植物主要由草本植物组成，草本植物占绝对优势。

Other plants such as gingergrass produce racemic carvone. Nature goes one step further; some botanically indistinguishable plants grown in different countries can carry out complete metabolic sequences of mirror-image

其他的植物如姜草会产生外消旋的香芹酮，自然发展更进一步：一些在植物学上不可区别的植物在不同的国家都有生长，它们可以进行一系列完整的与新陈代谢有关的镜像反应。

The garden??s characteristic is "the north catalpa plants in south and the south flower open in north", you can find the beverage bottle coconut tree, Canada tropical plants, betel nut and other tropical plant here. Meanwhile, you may understand the irrigation facility which introduces from Israel - micro spurts, the domestic origination vertical column type cultivation technology and other advanced scientific agricultural knowledge, it is undoubted that double income we have got, viewing beautiful scene and increase our knowledge!

观光园的特色是"南树北栽，南花北开"，在这里可以看到酒瓶椰子、加拿利海枣、假槟榔等热带植物，还可以了解到从以色列引进的灌溉设施－微喷、国内首创的立柱式栽培技术等先进的科学农业知识，真是观美景、长见识，双收益！

The results showed that the overexpression of CBF1 could obviously improve cold tolerance of plant.Compared with non-transformed control plants,the transformed plants had a shorter and stronger stem,more leaves that were bottle-green and thicker,and a longer growth period.

结果表明：CBF1的组成型表达增强了冷敏感植物的抗寒性；在表型上使植株矮壮，叶片着生密集，叶色深绿，叶厚度增加；促进侧枝生长，延长营养生长期，推迟花期；对植株的结实性无明显影响。

In this article made the cluster of phonological type by 4 of main phenophase with bourgeon period, leaf expansion period, flowering period and fruit ripenes period of observed data on phonology of 42 kind of plant 34 year in Minqin desert area, further the 23 of phenology classification merged by phonological type. The 23 of phenology classification basically obeys the ecotype characteristic of the plants, and the more scientific than the type of system cluster by plants sample. Moreover, the form of phonological type record by "ten day period + phonology" in the article.

以民勤荒漠区42种植物34年的物候观测资料，以萌动期、展叶期、开花期和果熟期4个主要物候期进行物候型聚类，进而将物候型归并为23个物候类型，聚合的物候类型基本上遵从植物的生态型特征，较系统聚类法直接用样本聚合的类型更加科学合理。

Norampac owns seven containerboard mills, four boxboard mills, 27 corrugated products plants, and five folding carton plants in the U.S., Canada and France.

拥有7 Norampac纸板厂，面粉厂四个纸板，瓦楞纸产品27个工厂， 5个折叠纸盒厂在美国，加拿年夜和法国。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
