营养根

The study of adventitious root formation is for the understanding andcontrolling of root development and vegetative propagation.

有关不定根形成机理的研究，是了解和控制根的发育和营养繁殖的基础性工作。

The nutritive components of Ampelopsis grossedentata were determined, and the use of its root, stem and leaf in the preparation of Ampelopsis grossedentata drinks was studied.

测定了藤茶植株的营养成分，并研究了其根、茎、叶在制备藤茶饮料中的应用，得到了两种新型的藤茶饮料配方。

Herbs small, mycotrophic, without chlorophyll, with a slender, scaly rhizome.

小的草本，菌根营养，没有叶绿素，具一纤细，有鳞的根状茎。

After the attack of cerebral ischemia, the expression of BDNF and Sema 3A may be related to the mechanism of neuronic injury and repairment. Puerarin may have protective effects on ischemic neurons

葛根素治疗后脑源性神经营养因子的表达增加，Sema 3A的表达下降，提示葛根素对脑缺血损伤具有保护作用。

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。

The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons.

作者认为3 d、6 d的减少主要与邻近背根节切除后，其神经纤维和膨体溃变有关；12 d时，保留的Ls背根逐渐侧支出芽，且与靶细胞再建功能联系，故脑源性神经营养因子阳性神经纤维和膨体数均趋于恢复。

In vegetative organs, BnPAP17-2 and BnPAP17-3 are expressed in root, hypocotyls and stem, while BnPAP17-1 expression is limited to root.

在营养器官中，BnPAP17-2和BnPAP17-3在根、下胚轴和茎中有一定程度的表达，而BnPAP17-1只在根中表达。

The results showed that tomato plant with AMF inoculated had higher dry matter production and more nutrient uptake than control plant without AMF inoculums.

而丛枝菌根对于植物生长和营养吸收有着很好的促进作用，土壤中富含有机质时菌根的作用更明显〔3，4〕。

I succeeded in establishing a mycorrhizal symbiosis between S. sinuosa and transformed Ri T-DNA carrot roots for the first time. The S. sinuosa sporocarps were found not to occur as single spores, but were observed to survive in groups of sporocarps in the environment.

利用双重培养方法首次成功培养了S.sinuosa的菌根共生联合体。S.sinuosa不是单个孢子，而是以孢子果的形式存在于自然界中。S.sinuosa孢子果的萌发是从孢子果的四周伸出芽管，在侵染根段的过程中，形成大量的营养孢子。

Three kinds of plug trays were used to grow watermelon seedlings which were grafted on shoot with root cutting.

0引言西瓜断根嫁接穴盘育苗技术已在全国推广，大多使用50孔的穴盘，由于购置的穴盘规格不同，穴盘的根际营养体积也不相同。

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.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
