长江口滨岸潮滩芦苇与海三棱草根系、茎叶以及根际沉积物中Cu、Pb、Mn、Zn、Cr的含量分析发现，Cu、Pb、Zn、Cr在根系中的含量较高，而Mn在茎叶中的含量达到总量的55%以上。

Based on the field investigations of Indiacharcial trema root morphology, one can establish a 2-D numerical model of soil/root system to simulate the pull-out test at field site.

依据山黄麻现地调查之根系形态，吾人可建构含根土之二维数值模型并进行现地根系拉拔抗力试验之数值模拟。

The results showed that soil type had significant effects on the root morphology and nodule traits of test varieties. In alfisol, the root dry mass, root length, and root surface area of test varieties were greater at the fifth trifoliolate stage and bloom-beginning stages while smaller after seed-beginning stage, compared with those in mollisol, and the average root diameter after seed-beginning stage was higher in alfisol than that in mollisol. Soil type did not affect root-shoot ratio. The nodule number after seed-beginning stage was much smaller in alfisol than in mollisol, while the nodule fresh mass and the mass per nodule were in adverse.

结果表明：土壤类型对大豆根系形态及结瘤性状均有显著影响，在第5片复叶展开期和初花期，暗棕壤的根系干质量、根长和根表面积低于黑土，而在鼓粒初期后高于黑土，暗棕壤的平均根直径在鼓粒初期后也高于黑土，但土壤类型对根冠比的影响不大；暗棕壤的根瘤数在初花期后明显低于黑土，但根瘤鲜质量和单个根瘤质量高于黑土。

A pot experiment was conducted with two soybean varieties (Di2003-1 and Hefeng25) and two main soil types in Heilongjiang Province to study the interactive effects of variety and soil type on the root morphology and nodule traits of soybean plants. Root samples were collected at the fifth trifoliolate stage, bloom-beginning stage, pod-beginning stage, full pod stage, seed-beginning stage, full seed stage, and full maturity stage for the analysis of root dry mass, root length, root surface area, average root diameter, nodule number, nodule fresh mass, and mass per nodule.

选取黑龙江省2种主要农田土壤类型和2个大豆品种（滴2003-1和合丰25），采用盆栽试验，分别于大豆第5片复叶展开期、初花期、结荚初期、结荚盛期、鼓粒初期、鼓粒期和完熟期取样，进行根系形态（根干质量、根长、根表面积和平均根直径等）和根瘤性状（根瘤数、根瘤鲜质量和单个根瘤质量）的动态分析，以研究品种和土壤类型对大豆根系形态特征的影响。

Along with forest succession, the percentage of C and N turnover through fine root to the root, soil and the belowground increases gradually and then decreases.

由高海拔到低海拔根系生物量逐渐增加，而细根的生物量则没有明显的变化规律，细根占根系总生物量的范围为11％～24％。

Meantime, the analysis also revealed that the morphologies of the root systems exerted influence on theirhydraulic conductivities.

同时表明，根系的形态特征对根系的水流导度也存在一定的影响。

Non-inoculum was used as the control. The plants were harvested after 60 days of growth. The results showed that AM fungi could colonize the roots of mung bean. Shoot dry mass of the bean was increased by AMF inocula, although there was no significant difference of the root between each treatment.

苗后60d收获植株结果表明，AM真菌能很好的侵染绿豆的根系，菌根侵染提高了绿豆地上部分的干重，而对根系的干重则没有显著的影响；同时菌根侵染也促进了绿豆的P营养。

Although large root diameter decreased Lpr in some way, Lpr varies more remarkably.

尽管进化中根系平均直径加粗，在一定程度上降低了水导，但根系水导的差异性比较而言要显著的多。

So that the osmotic stresses were decreased and it provided the basis on water purveying in plants.(2) Under the condition of salt stress, inoculating Gl. versiforme could improve the photosynthetic physiological characters of winegrape.

在水分生理效应方面，接种植株根系活性增强、水势降低，叶片维持了相对较高的水分蒸腾代谢水平，增加了酿酒葡萄植株根系水分吸收动力，最终表现出植体内水分含量的相对升高。
