目的采用薄层色谱法和高效液相色谱法对市售刺五加根、根茎、及茎中主要活性成分进行定性定量研究，比较刺五加根、根茎、及茎的质量。

Herbs perennial, often shortly rhizomatous, sometimes long stoloniferous, often glabrous, sometimes scabrous.

多年生草本，通常短根状茎，有时长有匍匐茎，通常无毛，有时粗糙。

If there are some septate internodes right up the basal stalk, especially if these internodes are near to each other, this plant will be much harder to be bended.4. The author drew a conclusion that: Brazier effect is the main cause of bending of hollow stalk plants.

在作物抗倒伏的研究上，认为在靠近基部处出现的茎节对抗倒伏的影响比较大，特别是从基部开始以较小的间距增加几个茎节，这样将大大提高作物抗倒伏能力。

Basal and cauline leaves 2 or 3; leaf sheath auricles well developed; leaf blade terete, 2--27 cm, on cauline leaves tubular and distinctly septate.

基生和茎生叶2或3；叶鞘的叶耳发育良好；圆柱状的叶片，2-27厘米，茎生叶上管状和清楚具隔的。

The stem of annual medics was erection type or stolon type,the stem height reached 7-30.7cm,seeds were yellow and kidney shape,the developmental stage was 95～140 days,the accessions of annual medics will be divided into prematurity type and serotinous type by the developmental stage.

通过对一年生苜蓿形态的观测和生育期的比较发现，一年生苜蓿的茎为直立或匍匐，茎高7cm～30.7cm，三出羽状复叶，种子为黄色、肾形。

Leaves not amplexicaul; stems and leaves often hairy and/or inflorescences sessile.

叶不抱茎；有毛的茎和叶通常和/或花序无梗。

Cauline leaves sessile, auriculate or amplexicaul, entire, dentate, or sinuate.

茎生叶无柄，耳形或者抱茎，整个，有齿，或者具深波状。

Cauline leaves petiolate or sessile, often auriculate or amplexicaul at base, sinuate, pinnately lobed, or pinnatisect.

茎生叶具叶柄或者无柄，通常耳形或者抱茎的在基部，具深波状，羽状浅裂，或者羽状全裂。

The results showed that different southernwood cultivars displayed different artemisinin contents, especially, the artemisinin contents of planting cultivars and the cultivars with coloured stem were higher. Further AFLP analysis indicated that a specific fragment was amplified respectively with the primers of EA04-MC05 and EA01-MC01. According to the differentia fragments, we clustering analyzed the 10 major kinds of southernwoods by utilizing WPGMA approach. However, there was no distinctly relativity between the artemisinin contents and diversity of AFLP analysis and just can distinguish, southernwood of Youyang county from Shapingba and Beipo in producing area which still illuminated that the heredity differentia of southernwood presented itself obviously in different area.

研究结果表明：不同的青蒿株系青蒿素含量不同，栽培株系和色茎株系青蒿素含量较高；进一步的AFLP分析表明引物组合EA04-MC05和EA01-MC01分别在高产青蒿株系和茎色青蒿株系中均能扩增出一条特异性条带；根据AFLP差异带，用WPGMA法对10个主要青蒿类型进行聚类分析，结果没有得到与青蒿素含量的明确关联，只是从产地上将酉阳青蒿与北碚、沙坪坝青蒿区分，说明不同地区青蒿的遗传差异较大。

Stalky or Stemmy: Describes an unpleasant greenness and astringency from overlong contact with the grape stems or the use of underripe grapes .
