有穗的

They are distinguished mainly by habit, Urochloa having rather more flattened, cuspidate spikelets enclosing a pronounced mucro from the upper lemma.

他们以有相当更扁平的体型，Urochloa 主要区分，小穗包围这上面外稃的显著短尖头。

The comparison on different planting densities of hybrid maize Qianxing 201 showed that in 6 density treatments,the yield of the treatments with planting density of 67 500 plants/hm^2 occupied the 1st position,with the best character performance,trimly plants and stronger disease-resistance in the growing stage.

杂交玉米黔兴201不同种植密度比较试验结果表明：6个密度处理中，种植密度为6.75万株/hm2的产量居第1位，各种性状表现较好，生长期间植株整齐一致，抗病性较强；密度为7.50万和6.00万株/hm2的产量分别居第2位和第3位，综合性状表现好；密度为4.50万和5.25万株/hm^2，虽然穗粒数和千粒重较大，但产量不高；密度为8.25万株/hm^2，有轻微倒伏现象，造成部分果穗腐烂。

Inflorescence terminal, composed of several to many racemes inserted digitately or along a short axis; racemes elongate with many spikelet pairs, hairy, fragile, sessile and pedicelled spikelets of a pair similar, pedicelled often slightly narrower, both fertile; rachis internodes linear, ciliate along angles; pedicels resembling internodes, usually slightly shorter and more slender.

花序顶生，由数枚到多数总状花序组成着生或沿着短轴；总状花序拉长具很多小穗对，有毛，脆，无梗和pedicelled相似的对，pedicelled通常稍狭窄，都能育；轴节间的线，纤毛的沿着棱；花梗象节间，通常有点更短和更纤巧。

Pantropical floating plant forming a rosette of wedge-shaped leaves; a widespread weed in rivers and lakes.

热带的飘浮水生草本属，叶片数枚聚生而成一杯状体，有少数花组成肉穗花序；在河流、湖泊中广泛生长的一种野草。

At first sight it is difficult to distinguish the sessile and pedicelled spikelets because they look very similar and, since the pedicel is fused to the rachis internode, both spikelets are in effect sessile. However, the sessile spikelet of a pair can be distinguished by its basal callus, which normally has an oblique articulation line beneath it.

乍看起来区分无梗和pedicelled小穗很难，因为他们看起来非常相似，不过，那些无梗对因为它的基部胼胝体可以区分，通常有偏斜节它以下的线。

Fusarium species are varied and it distributes widely. Some of them are the pathogens which are the result of a variety of agriculture, forestry, plant disease, it can cause the wilting of crops, ear rot, decay and other diseases.

镰刀菌种类多、分类广，其中有不少是导致多种农林植物病害的病原，它可以引起作物的萎蔫、穗腐、腐烂等病害。

Spikelets robust, 4–12 flowered, followed by a sterile floret, pedicels long.

粗壮的小穗，4-12花，随后有一不育的小花，花梗长。

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。

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。
