For example, the basic angiosperm stem is vertical and elongated, but some cacti have swollen water-storing stems, while other xerophytic plants that have lost their leaves during the course of evolution have evolved flattened leaflike stems for photosynthesis, e.g.

例如被子植物的茎是垂直的，伸长的，但一些仙人掌具有膨大的能够储水的茎，另一些旱生植物在进化的过程中失去了叶子，但又发展为利用扁平叶状的茎来进行光合作用。

Of these, Colletotrichum (25.54%) was the most prevalent genus, followed by Alternaria (11.56%) and Xylaria (7.80%). The most dominant fungi appeared in the stems from ka (19.89%), ck (19.62%) and ma (18.82%), while the least appeared in the fruits from ka (5.11%) and ku (6.18%).

各组织获得菌株数量比例最大的分别为ka种源茎部(19.89%)、ck种源茎部(19.62%)和ma种源茎部(18.82%)；最小的为ka种源果实部(5.11%)和ku种源果实部(6.18%)。

GUS staining shows that GUS gene was expressed in stems, leaves, calyxes, stamens and siliques in transgenic Arabidopsis plants, with higher expression in green tissue such as stems, leaves, siliques, while invisible in roots, petals, and seeds. The data indicate that MPBQ MT gene promoter was likely to be expressed preferentially in green tissues such as stems, leaves, and young siliques.

GUS组织化学染色结果表明，在MPBQ MT启动子驱动下，报告基因GUS在拟南芥的茎、叶、花萼、雄蕊、种荚均有表达，且在茎、叶、种荚中表达量较高，而在根、花瓣和种子中则没有观察到GUS基因的表达，表明MPBQ MT基因可能仅在拟南芥幼嫩茎、叶、种荚等绿色组织中特异性高表达。

On the basis of the stem heat balance principle to measure the plant transpiration, with the instruments to collect meteorological data in greenhouse, we studied the variation rules of tomato sap flow under different environmental treatments through shading and obturating environment.

在茎热平街技术测定植株茎流的原理基础上，结合温室内气象数据采集仪器，通过对小温室做遮光、密闭处理，探讨番茄茎流的变化规律。

After Bahia grass shoots and leaves were fermented perfectly, the 1% fermentation liquid and fermented shoots and leaves of Bahia grass were amended respectively into pots in which pot soil contained very high density AM fungi propagula (2600 spores per 50g soil).

与对照相比，百喜草茎叶发酵液和发酵茎叶处理的苗木，无论是苗高、根鲜重或者是整株苗鲜重，都表现出显著的生长促进效应，尤其是发酵百喜草茎叶处理，对积苗生长具有极显著的促进作用。

Main stems erect or climbing, generally branched, with cladodes in axils of main stems and branches.

主茎直立或攀援的，通常是分枝，具扁茎在主茎和分枝腋处的。

The results showed that five bands including POD-1, POD-2, POD-3, POD-4 and POD-5 were detected in the gel of POD as well as EST-1, EST-2, EST-3, EST4 and EST-5 for EST. POD-3 and POD-4 were common in all the tissues, but most intensive in F. tartaricum. POD-2 was only discovered in the leaves of F. cymosum and caudex of F. cymosum 1. Although there was some difference between the location, POD-2 appeared in the caudexes of three buckwheat and root of F. tartaricum. POD-5 was detected in all leaves and caudx of F.

结果显示，POD和EST都检测到5条谱带，包括POD-1，POD-2，POD-3，POD-4及POD-5，其中POD-3及POD-4在所有组织中都存在，但在苦荞麦1号中的带最强；POD-1只在金荞麦叶片及金荞麦1号茎中出现；POD-2在茎组织及苦荞麦1号根中存在，但在金荞麦及苦荞麦中的位置不同；POD-5存在于叶片及苦荞麦1号茎中，在苦荞麦的带较强。

Stem/leaf ratio of all of seven lines was lower than that of the corresponding alfalfa varieties in both cutting. In the first cutting stem/leaf ratio of BHJR5 was the lowest and in the second cutting stem/leaf ratio of BHSHS6 was the lowest.

57个白花品系第一茬和第二茬的茎叶比均小于相应的紫花母株，其中第一茬BHJR5的茎叶比最小，第二茬BHSHS6的茎叶比最小。

In order to lower the difficullties of peeling shoot tips and to set up a rapid propagation techniques of good quality S.grosvenorii seedling ,we carried out the experiment in two ways:(1)peeling the shoot tips after heat thrapy at 38.5℃ for 7 days ,10 days ,15 days. Plants derived from 0.2~0.5mm heat treated (38.5℃;10 days )meristems were 100% free from disease.

为降低剥茎尖难度和大规模生产罗汉果优良种苗，本试验探讨了：（1）在38.5℃条件下对罗汉果试管苗热处理7天、10天、15天，然后剥取0.2~0.5mm、0.6~1.0mm和1.5~2.0mm的茎尖进行培养，结果表明，热处理10天，剥取0.2~0.5mm的茎尖进行培养，可获100%的脱毒苗。

The plant height (160 cm) and the amplitude of Deep water (50 cm) scenario were higher than Shallow Water (0 cm) scenario, while that of Draught (20% water content) scenario did not increase and some of the sedges died.

漂筏苔草无性株地上茎茎粗随着淹水深度的增加而增加，生长季茎粗的变化主要发生在6月份，其次是5月份和7月份，8月份茎粗变化微小（在50cm淹水状态下）。

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.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
