生根

Root-lodging grade was significant correlation with height of plant and ear and number of brace root, but non-significant correlation with stem quality properties.

遗传分析表明，株高和穗位主要受基因非加性效应支配，环状气生根的基因加性和非加性效应相当，故对根倒伏的抗性应强调非等位基因的互作，亲本之一必须抗根倒才能有望配成抗根倒的杂交组合。

The result showed that with the increasing of density, plant height was increased, stem diameter and ear diameter was decreased, ear was shorten, rare top length、No. of ear nod、ear height was increased;brace root number and total root number was decreased, the rate of root dry weight was increased within farming layers; population dry matter accumulation was increased and plant dry matter accumulation presented the opposite trend; ear linage、kernels per ear、100-kernels weight、double-ear rate、plant yield was decreased, yield was increased and decreased successively.

结果表明：随群体密度的增加植株高度增高、茎粗、穗粗变细、果穗变短，秃尖长度、穗位节数和穗位高度呈现增加的趋势；气生根与总根数减少，耕层根系干重比例增加；群体干物质积累量随密度增加而增加，单株干物质积累量呈相反的趋势；穗行数、穗粒数、百粒重、双穗率、单株产量均随密度的增加而减低，群体产量先增后降。

Not to speak of its grosser phases, Hinduism, even in its highest form known as Brahminism, could not take root and flourish in countries where the caste system and the intricate network of social and domestic customs it implies do not prevail.

不说话的大阶段，印度教，甚至在其最高形式称为Brahminism ，不能生根和蓬勃发展国家的种姓制度和错综复杂的网络社会和国内海关这意味著不占上风。

The results indicated that the content of MDA and root-shoot ratio were increased, but the dry weight of root, total root length, secondary root number, root activity, the SOD activity of root, the height of plant and aboveground dry weight of broomcorn millet decreased significantly with drought treatment regardless of fertilizing or not.

不同施肥水平下黍子根系对干旱胁迫的生物学响应研究表明，无论施肥与否，拔节期或抽穗期干旱胁迫均会使黍子根重、根长、根活力、次生根数、根系SOD活性及株高与地上部干重明显降低，MDA含量明显增高；水分胁迫解除后，黍子根系增长迅速，表现出明显的补偿效应和根系对水分反应敏感的特点，但干旱造成的不利影响在后期未能完全补偿。

Joins WTO along with China, more and more many multinationalcorporations in Chinese Bryophyllum Pinnatum.

Through a study on tissue cultureof the bud scale of corm of Lili longiflorum separated from the plant ,several practical TC prompt proliferation techniques ,such as inducing of lush bud ,proliferation cultivation of successive generation, cultivation of growing roots and transplanting , etc., are researched in this paper .

通过对百合球茎鳞片离体组织培养的研究，探讨了丛生芽诱导、继代增殖培养、生根培养及移栽等方面的组培快速繁殖以及生产上实用的组培技术。

In this experiment,we studied the effects of different medium on the bulblet formation,condition of growth and rooting.

针对不同培养基对百合苗增殖情况、长势及生根情况等方面进行了研究，结果表明，在高无机盐浓度并附加高浓度BA和低浓度NAA的培养基上适合百合苗的继代培养。

The research aimed to confirm the suitable hormone kinds and level for rooting induction of bulblet in tissue culture seedlings of narcissus.

［目的］确定水仙组培苗小鳞茎生根诱导的适宜激素种类和水平。

The test-tube plantlet was formed after rooting, through the virus detection on test-tube plantlet, the plant without virus was selected out and the bulblet was obtained through transplanting.

生根后形成试管苗，通过时试管苗的病毒检测，选择不带病毒的植株，移栽得到小鳞茎。

Using the tissue cultured bulblet of narcissus cultivar Fortissimo as tested materials, with 1/2MS as the basic medium, 4 conch, of NAA and IBA including 1.0, 0.5, 0.1 and 0.05 mg/L were set up to study the effects of hormone on rooting induction of tissue culture seedlings in narcissus.

方法］以水仙栽培品种Fortissimo的组织培养小鳞茎为试验材料，以1/2MS为基本培养基，设计1.0、0.5、0.1，0.05mg/L 4个NAA、IBA浓度，研究激素对水仙组培苗生根诱导的影响。

Fancy gold-plated dangling earrings with facetted White Opal crystals.
