查询词典 ecotypes

Through the research we have established in planta transformation system, mutangenesis and screening system for salt sensitive mutants, and constructed a cDNA library under salt stress and cloned a serious of salt-tolerance related genes which had been confirmed the function by overexpression in Arabidopsis or antisense expression in Thellungiella. We also compared different mapping strategy through the analysis of the genetic polymorphism between ecotypes, and establishing mapping population for physical mapping.

建立了小盐芥的转化体系与盐敏感突变体诱变与筛选体系，构建了盐胁迫下的cDNA文库并克隆了一批耐盐相关基因，并通过模式植物拟南芥转化与小盐芥的基因反义表达证实其功能，通过不同生态型小盐芥的遗传多样性分析探讨了基因组作图的策略，建立了作图群体并开始进行物理图谱构建。

This indicates that these terrestrial reed ecotypes can synthesizeABA in their roots and translocate root — soureced ABA to their shoots.

这说明三种陆生芦苇可在根中合成ABA并运输到地上部分。

Two ecotypes of reed (Phragmites communis Trin.), swamp reed and heavy salt meadow reed growing in the desert regions of Hexi Corridor are ideal materials for mechanism study on salinity-resistance/tolerance of plants.

分布于甘肃省河西走廊沙漠地区的不同生态型芦苇（水生芦苇和重度盐化草甸芦苇）是研究植物抗/耐盐机制的良好材料。

This article attempts to attain the research goal that is identifying the ecotypes of wet lands located at the source of Yellow River on the basis of the operation of slicing which was imposed on NDVI ,TM4 and the wetness component derived from the Tasseled cap transform and the operation of classification which was implemented based on the characteristic images coming from LBV transform.

本文尝试基于NDVI，TM4，缨帽变换湿度分量进行密度分割和基于LBV变换图像进行分类的方法达到识别黄河河源湿地生态类型的研究目标。

The results showed that there were significant differences among fungal species or ecotypes in all above index,which varied with soil types.First,six fungi could colonize maize root on three soils,and the fungal colonization rate was higher on soil collected in the region that had been screened for cinnamon soil and brown soil.

结果表明，6种菌株在上述指标上存在显著的种间或生态型差异，土壤与菌株间存在显著的交互作用。6种菌株在3种土壤上都能与玉米形成菌根，在褐土和棕壤上大多数菌株在分离地所在地区土壤类型上的菌根侵染率较高，说明其对该土壤条件的适应性较强；在红壤强酸性土壤条件抑制了菌根真菌的侵染。
