查询词典 leaf-shaped

At present the mechanism of endangered species mostly confined to the morphology point of view, few physiological point of view of ecology, the lotus leaf fern Adiantum growth conditions of the study also stay in more qualitative analysis, there are few quantitative analysis of its optimum growth environment , The experimental use of morphological and physiological ecology of the idea and will use the components of the research methods, to be a long time to further explore their own independent development of plant taxonomy, morphology, physiology, ecology and other subjects the intrinsic link between , With a view to a new high on the survival of endangered species, adaptation and evolutionary mechanism.

目前对物种濒危机理的研究大都局限在形态学角度，很少有生理生态学角度的研究，对于荷叶铁线蕨生长条件的研究也多停留在定性分析上，很少有定量分析其最适生长环境，本实验采用形态学与生理生态学结合的思想，并将采用构件理论的研究方法，拟进一步探讨长期以来各自独立发展的植物分类学、形态学、生理学、生态学等学科之间的内在联系，以期能在一个新的高度上探讨濒危物种的生存、适应对策和进化机制。

Therefore, the lotus leaf fern Adiantum mainly in the growth of other plants rarely Uncovered Rock steep slopes or cliffs, these habitats and soil glare and often subjected to drought stress and thus not conducive to update the population and survival.

因此，荷叶铁线蕨主要分布在其它植物很少生长的陡坡裸岩或峭壁上，这些生境土壤瘠薄且经常遭受强光和干旱胁迫，从而不利于种群更新和生存。

These had a gene adit to interfere with the biological causes of leaf loss during drought.

它们被添加了在干旱条件下能干扰引起叶子损失的生物因素的基因。

There is a great quantity of aerenchyma and secretory canals distributed in root, stem and leaf .

根、茎、叶中均有发达的通气组织和分泌道分布。

The plant body tends to form great deal of aerenchyma under the saline-alkali habitat. The aerenchyma in three kinds of plants comes into being near the main vein and in spongy mesophyll of the leaf, in parenchyma tissue around of vascular bundle of the petiole, and in parenchyma tissue of cortex of the stem.

盐碱诱导下植物体趋向形成大量的通气组织，以对抗盐碱生境下的乏氧环境，三种植物的通气组织一般存在于叶片的主脉附近，叶柄的维管束周围的薄壁组织中，以及茎的皮层薄壁细胞之中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
