An ornament, a symbol, or an architectural form having the appearance of a trifoliate leaf.

蚤草一年生的欧亚植物有对生叶片，浓密的穗中长有小花

The ash green leaf and stem , long spike and red unfull grain from triticale are expressed in interspecific hybrid F1, which are regard as typical traits of identifying hybrids.

六倍体小黑麦的灰绿色叶片或茎秆、穗长长和红色不饱满的籽粒在杂种F1代显现，可作为鉴别真假杂种的典型性状。

The results were as follows: Compared with natural growth, defoliating and shielding photosynthesis organs decreased the contents of starch, fat and iron in wheat grains and yields of starch, fat, protein, ash, phosphorus, potassium, zinc, iron and calcium in a single ear.

结果表明，剪叶遮光后小麦籽粒中淀粉、脂肪、铁含量比正常生长降低，灰分、磷、钾、锌、钙含量提高，而对蛋白质含量影响很小；剪叶遮光后小麦籽粒淀粉、脂肪、蛋白质、灰分、磷、钾、锌、铁、钙单穗产量均比正常生长降低。

Oil pollutants not only impact wheat emergence, plant height, panicle length but also the germination rates of corn, soybean and cotton seed which is the impacted mostly. Through field comparative analysis between apple trees near wells and those without pollution, index of leaf senescence of fruit trees, apple leaf chlorophyll content and nutrient composition are impacted slightly by the development of oil.Specific measures for the environmental impact of oil development should be issued systematically from the perspective of the government and the public.

石油类污染物对小麦的出苗率、株高、穗长影响较大；石油类污染物对玉米、大豆和棉花种子的发芽率均有影响，其中影响最大的是棉花种子；通过野外调查选择油井附近的苹果树和对照点没有污染的苹果树进行对比分析，发现石油开发对果树的叶片衰老指数、叶片叶绿素含量和苹果的营养成分等影响较小。

The most significant variance lay in the 1000-seed-weight,followed by flag leaf length and inflorescence shape and then by distance between flag leaf and inflorescence with least in inflorescence length,plant form,leaf width and seed length.Meanwhile,morphological characteristics of D.glomerata have significant relationships: those with upright and constrictive inflorescences hav...

其中，种子千粒重变异最大；旗叶长度、花序形状次之；穗叶距、花药宽度、旗叶宽度等性状变异中等；而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性，花序直立、紧缩的鸭茅，叶片窄长，茎秆粗壮，旗叶较长，雄性生殖器官发育良好，结种性能强；而花序下垂、开展的鸭茅则与之相反。3聚类分析表明，不同野生鸭茅种源可划分为3类，其中花序下垂种源聚于一类；而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析，花序直立的鸭茅更具开发利用潜力。

With the growth progress, the P and pro in all tested leaves gradually decreased. The dynamic changes of Chl in leaves showed different patterns, with little changes at different assaying points in the lower leaf and a single peak curve in the ear leaf and upper leaf.

植株不同叶位P和Pro随生长进程均不断下降；不同叶位Chl的变化动态表现为下位叶在各测定时期之间差异较小、穗位叶和上位叶为单峰曲线。

Identification of disease and pest resistance was done by Institute of Plant Protection, Hebei Academy of Agricultural Science, and the variety demonstrated resistance to southern blight leaf; mid-resistance to stalk rot, corn Curvularia leaf spot; high resistance to northern blight leaf, corn smut, corn dwarf mosaic; and sensitive to corn borer.

项目简介：中单808由中国农业科学院作物育种栽培研究所选育，生育期126天左右，株高314cm左右，穗长21.8cm，2004年河北省农林科学院植物保护研究所抗病鉴定结果：抗小斑病，中抗弯孢菌叶斑病，茎腐病，高抗大斑病，瘤黑粉病，矮花叶病，感玉米螟。2005年西南生产试验中平均亩产571.29kg，比对照增产17.85%。

Meantime, the performance of OPTC-11 was verified with Xiaoyan 22, a cultivar heaving blood from long-spike oat grass so that its importance was confirmed in molecularly-aided breeding.

同时，具有长穗偃麦草血缘的小麦品种小偃22对OPC11进行了验证，明确了其在分子辅助育种中的价值。

Here are the results: there are no clear difference in the length and width of leaf epidermis stomatal apparatus, stoma density and vascular bundle area in 1st internode below the ear between cold and warm type wheat. The vascular bundle area in 2nd internode below the ear of cold type wheat is obvious smaller than warm type wheat's. There are clear difference in the vascular bundle number in unit transverse area of 1st internode and 2nd internode below the ear and the rate of the total area of vascular bundle and the transverse area of wheat stem between cold and warm type wheat.

研究表明，冷、暖型小麦叶表皮气孔器的长度和宽度、气孔密度、穗下节间中维管束面积均无显著差异；冷型小麦倒二节间中维管束面积明显小于暖型小麦；冷、暖型小麦穗下节间、倒二节间单位横截面积中维管束数目、维管束总面积占茎横截面积的百分率均有显著差异。
