查询词典 leaves

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

The results demonstrated that the quality and usability of unripe tobacco leaves were lower than those of mellow leaves.

Shaded 60%in seedling stage,Fv/Fm and AQY of ginger leaves increased,but MDA content,SOD activity and Pn decreased.Pn,AQY and Fv/Fm of ginger leaves treated with DDTC decreased whether shading or not,but the effect of DDTC on shaded plants was less than that on unshaded plants.

苗期遮荫60%，Fv/Fm与AQY明显提高，MDA含量降低，SOD活性减弱，Pn降低且日变化曲线变为"单峰型"，表明苗期适当遮荫有利于提高光合效率和PSII光化学效率，减轻光抑制和光氧化。

The earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree,which precede flowers and fruit —— not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic.

大地不只是已死的历史的一个片段，地层架地层像一本书的层层叠叠的书页，主要让地质学家和考古学家去研究；大地是活生生的诗歌，像一株树的树叶，它先于花朵，先于果实；——不是一个化石的地球，而是一个活生生的地球；和它一比较，一切动植物的生命都不过寄生在这个伟大的中心生命上。

Since San Jose, CA weather pattern is different than the climate in Taiwan, it is hard to say how soon the new leaves will show up but I have no doubt they should have already grown new and mature leaves by now.

由於加州圣荷西天气形态和台湾不同，因此很难去说要多久才会长出新叶，但我相信此时它应该有长新的且成熟的叶子。

The cultural technique measure before pick which through establish different result altitude when the grape branch is unearthed and the branch is tied, taking off the leaves at color change time, Shop reflective film under surface, Research the influence which through the cultural technique measure of change wine grape micro-climate on the quality of wine grape, The results showed that,Fruiting by 70 cm height, the results of the processing site to taking off the leaves , Shop reflective film under surface ...

通过在葡萄枝条出土、绑蔓期间设置不同的坐果高度，在葡萄转色期进行摘叶、架面下铺设反光膜等采前栽培技术，研究改变葡萄微气候的技术措施对酿酒葡萄品质的影响。结果表明，采用70cm的坐果高度、对结果部位进行摘叶、在架面下铺设反光膜的处理方式能够使酿酒葡萄的品质得到一定的提高。

The leaves of some types turn colors in the fall, and after the leaves drop certain varieties add interest to the garden in winter with their bright red or yellow bark.
