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 analysis of principle components,the breeding materials with higher plant height, mediate stem perimeter, thickerbast fiber, higher rate of bast fiber to stalk, should be selected to resolvethe conflict between quality and yield in kenaf breeding.

根据主成分分析结果，在品种选育时，应注意选择植株较高、茎粗中等、韧皮较厚、皮骨比较高和高出麻率和品质优良的材料，以协调品质与产量的矛盾。

The abnormal forms and the variations of other characters were observed or examined, such as plant short, leaf variations(contain leaf etiolation, leaf notch, leaf roll, and main leaf vein partial nondisjunction, etc.), growing period, cold hardiness, scourge-like caudex differentiation, corm weight increase, and so on.

这些可观察或可检测的变异有形态异常，主要表现为植株矮小及叶片畸形（包括叶片黄化、缺刻、叶卷曲及主叶脉粘连不分离等）；还有其它的性状变化，如生长期、根系、鞭状茎分化、耐寒性，球茎增重和产量等。

The leafstalk, chief vein, bud, the cane top on side branch, bast and xylem of type B had type A and C tow components, belonging to chimeric tissues. The leaf pulp and thin leaf vein had no components of type C, belonging to pure tissues of type A. Type B plant had two kinds of color roots, the rufous roots belonged to type A tissue, the yellow roots belonged to type C tissue through the SSR identification.

深州杨B型的叶柄、叶主脉、芽、侧枝茎尖、韧皮部、木质部同时检测到深州杨A、C型两种成分存在，属于嵌合组织，B型叶肉及细叶脉中检测不到深州杨C型成分，属于深州杨A型纯合组织；深州杨B型植株的地下部分含有红褐色和土黄色两种根，经检测，红褐色根是属于深州杨A型的纯合组织，土黄色根是属于深州杨C型的纯合组织。

With these 2 elements mark is opposite 10 China sweet potato advocate grow breed to undertake detecting, earnings result and result of groovy method appraisal agree completely, show 2 elements mark can be used at sweet potato to fight mark of cauline wireworm ill element to assist breeding.

用这2个分子标记对10个中国甘薯主栽品种进行检测，所得结果和常规方法鉴定结果完全一致，表明2个分子标记可用于甘薯抗茎线虫病分子标记辅助育种。

The entire Superstructure cross-section, except for traffic barrier, shall be considered to be placed at one time for purposes of determining support requirements and designing falsework girders for their stresses and deflections, except as follows: For concrete box girder bridges, the girder stems, diaphrams, crossbeams, and connected bottom slabs, if the stem wall is placed more than 5 days prior to the top slab, may be considered to be self supporting between falsework bents at the time the top slab is placed, provided that the distance between falsework bents does not exceed 4 times the depth of the portion of the girder placed in the preceding concrete placements.

整个上部结构截面除交通障碍，应被视为在一个确定的要求和支持他们的设计应力和挠度除，脚手架时间放在梁的目的如下：对于混凝土箱形梁桥，主梁茎，diaphrams，横梁，和连接底板，如果干墙放置超过5天前向顶板，可能被认为是自我支持之间的脚手架本茨当时顶端板放置，只要脚手架茨之间的距离不超过4倍，在前面的混凝土主梁部分存款放在深度。

In order to research the sugar accumulating regulation of sweet sorghum, the relationship between the brix of every internode and average brix of its whole stem was studied. This paper used varieties MNS-1, MNS-2 and stem brix of sweet sorghum in different period. The result showed that the variation of early matured and late matured varieties of sweet sorghum had same tendency in brix in same growing period, but had different values.

为了解甜高粱茎秆中糖分积累规律，研究甜高粱自基部至顶部各茎节间锤度关系及各茎节锤度与主茎秆平均锤度的关系，以示范推广品种MNS-1、MNS-2为材料，测量了不同时期甜高粱的茎秆锤度值；采用相关等分析方法对各茎节间锤度及与主茎秆平均锤度的关系进行分析。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
