A research platform was constructed for gene cloning and functional analysis in Eupatorium adenophorum in this study to provide a theoretical basis for the all-sided control of this malignant weed through the research in metabolic pathway related to allelochemical. By the study, we try to find out the coding gene of key enzyme which is related with the metabolism of allelochemical and clone some novel genes which can be used in agricultural production.

针对紫茎泽兰基因的克隆和功能分析建立了研究平台，通过开展紫茎泽兰的化感相关的代谢途径的研究，为这种恶性杂草的综合治理提供理论依据，以期能够找到调控化感物质代谢的关键酶的编码基因，发掘一些能够为农业生产所利用的新基因。

False spikes terminal on apical 2/3 of stems and branches, in panicles; corolla limb projected at an obtuse angle to tube; stems covered with golden yellow, rusty brown, or purple villous or strigose hairs, hairs to 2.5 mm

在顶端的2/3的茎和分枝上顶生的假的穗状花序，在圆锥花序里；对筒部在一个钝角凸出的花冠瓣片；为金黄色所覆盖的茎，锈色的棕色，或紫色具长柔毛或毛，毛兑2.5毫米 9 Teucrium quadrifarium 铁轴草

The traits of dedifferentiation and redifferentiation of the explants form H. sampsonii show that the calli the stem and leaf usually form buds at its parietal cells. In the presence of auxin, the parenchyma of the leaf gap at the node is initiated firstly, then, develops blastemata that form buds in a cluster on the node without callus. These show that the various parts ofthe herb differ greatly in cell initiation and organ differentiation.

研究元宝草外植体的脱分化和再分化的特点结果表明，茎段和叶片启动形成愈伤组织，其不定芽通常发生在愈伤组织的周边区，茎节叶腋的叶隙薄壁组织在激素的诱导下启动、分裂，不形成愈伤组织而直接器官分化成芽原基，并在节结处产生一圈成簇的不定芽，表明元宝草不同部位的细胞启动及器官分化调控存在差异。

Corolla pale blue, with distinct deep blue lines, lobes elliptic-lanceolate to elliptic; stem leaves lanceolate to broadly lanceolate, base subamplexicaul; stem fastigiate branched from base

浅蓝色的花冠，具离生的深的蓝色的线，裂片椭圆状披针形的到椭圆形；茎生叶披针形到宽披针形，基部；茎帚状的分枝自基部 4 Lomatogonium longifolium 长叶肋柱花

Don.methodswith the stem of sterile seedling and fresh plants as exophyte, ms as a basic medium, 6-ba and naa hormone were adopted as the experimental variables.resultsms +1.0 mg / l 6-ba +1.0 mg / l naa induced the best effect of callus; higher concentrations of 6-ba with high concentrations of naa made callus densification and higher rate.conclusion different plant hormones and their different concentration ratios have different effects on the callus of halenia elliptica d.

方法以椭圆叶花锚种子培养的无菌苗的茎和新鲜植株的茎段为外殖体，ms为基本培养基，分别以6-ba和naa两种植物激素为变量进行实验研究。结果ms培养基+1.0 mg/l 6-ba+1.0 mg/l naa对诱导椭圆叶花锚愈伤组织的形成效果最佳；高浓度的6-ba配合较高浓度的naa诱导的愈伤组织致密，出愈率高。

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

模型利用抽穗期植株临界含氮量来表达氮素最大积累量，引入叶片潜在分配指数和茎鞘潜在分配指数2个品种遗传参数来区别不同品种在器官间的氮素分配差异，采用Richards方程来描述大麦花前氮素积累动态变化；采用指数函数方程来描述叶片氮的转移量随叶面积指数的动态变化以及籽粒从土壤中吸收的氮量随干物重的动态变化；采用非线性函数方程描述茎鞘和穗部的氮浓度随生理发育时间的动态变化。

More assimilation products were stored in sheathes than those in leaves. 2After rewaterring, net photosynthetic rate and evaporation rate came back quickly, especially D3 and D6 groups whose two photosynthetic indexes were higher than that of control group and then droped back to normal in serveral days.

同化产物在叶片中的含量高于茎鞘，但叶片中的氮素含量低于茎鞘。2恢复灌溉后，受到胁迫的处理组的光合速率、蒸腾速率都迅速升高，干旱3 d和6 d的处理组光合水平超过对照，然后又有所下降，水分利用效率因为蒸腾速率的骤然升高而降低，之后有所恢复。

Leaves are generally semi-evergreen, made up of 3-9 lanceolate or ovate leaflets that are deep green during the growth period, and change color to purple-green in autumn. Flowers of 5-10 cm across are set singly on long stems (10-15 cm) growing out of leaf axils. They comprise 4 to 8 oval, slightly wavy edged tepals which are creamy white and have a pale green central bar on the outer side. In autumn flowers turn slightly greenish.The striking appearance of the blooms is due to its unusually long contrasting stamens consisting of deep crimson-purple, almost black anthers set on filaments that are white at the base and violet at the top.

茎细长，有明显的纵条纹，茎长能达2米，靠叶茎攀爬在附着物上生存，叶对生，3-9个毛尖形或卵圆形叶片，叶片在生长期是深绿色，秋天变为紫红色，花朵直径5-10cm，在10-15cm长的叶腋处伸出，有4-8个卵形或圆形的微小苞片，苞片微微卷起，淡黄色，外面有浅绿色中心状条纹，秋天花朵变成浅黄绿色，花朵迷人魅力在于从深红色到深紫色一系列花色组成的雄蕊，深黑紫色的花药，由一些美丽的花丝组成，这些花丝的底部是白色，顶部是紫罗兰色，基部是白色。

She is divided into M-shaped legs, pulling me in her soft body Without bones, I am impulsive waves, the stem hard to push her to the Department of the private, this is my first time, stem the first time contact with the woman's genitals,like imaginary dreamlike feeling and can not be implicit.

她把双腿分成M形，把我拉在她的柔若无骨的身上，我一阵阵冲动，把硬梆梆的茎向她的私部推去，这是我的第一次，茎第一次与女人的阴部接触，那种感觉如梦如幻，一时难以言明。

The amount ofethylene release by shoot apex and root showed no difference between iron-deficient treatment and control plants above before the appearance ofrelatively high reductase activity,which indicated that ethylene may not playa direct role in regulation of root ferric reductase activity,and the inhibitionof which by〓and〓may be caused by other reasons.

缺铁处理植株茎尖和根系乙烯释放量的测定结果显示，三种植物中，缺铁与对照植株的茎尖及根系所释放的乙烯可能不直接参与缺铁根系还原酶的调控，〓和〓对缺铁根系〓还原酶活性的抑制可能是其它原因所致。
