DGGE分析结果表明紫茎泽兰入侵降低了细菌的多样性，这与培养所得的结果是一样的。

The DGGE result indicate that the bacterial decreased because of the invasion too .

紫茎泽兰（EupatoriumAdenophorum）是我国主要外来入侵植物之一，在我国西南地区迅速传播，引起了巨大的经济损失。

Eupatorium adenophorum is one of main invasive plants in China and has caused great economic losses .

以MS+6mL（1mg/mL）2,4-D培养紫茎泽兰叶片分化良好，愈伤组织生长速度快；

Callus of Eupatorium adenophorum could differentiate and grow well in MS medium ( with 6 mL of 2,4-D 1 mg / mL ) .

X射线能谱分析说明根系内K的主动吸及Ca的被动吸收被紫茎泽兰内含的异克物质严重干扰，导致根系发育受阻。

The analysis of EPMA showed that the active transportation of K and the passive transportation of Ca in maize roots were obstructed , which retarded the growth of maize roots by allelopathic materials contained in plants of Eupatorium adenophorum .

结果表明，两种真菌及其毒素均能在紫茎泽兰叶片上产生直径2～5mm的局部坏死斑。

Results showed that toxin could influence the Eupatorium adenophorum lesion on leaf which diameter was up to 2 ~ 5 mm , which is obviously differenced from the influence by water .

主要结果与结论如下：1.嵌套PCR结果表明紫茎泽兰入侵改变了包括AMF在内的土著菌根真菌群落结构，并更多的在其根周积累了球囊霉属AMF。

The main results and conclusions were as follows : 1 . The results of nested PCR showed that , the structure of MF community including AMF was altered by A. adenophora invasion , and Glomus was accumulated in A. adenophora rhizosphere .

黑麦草与紫茎泽兰在所有密度及其比例下的相对产量总和（RYT）均近似于1.0，说明这两种植物面临着对相同资源的直接竞争。

The RYT was close to 1.0 , which implied that the two plants competed for the same resources . At all densities and proportions the yield of E.

电导率测定结果表明，毒素粗提液对紫茎泽兰的伤害活性最强，LA-I次之，LA-II最弱。

The results of conductance rate measurement indicated that the damage of the crude toxin solution to Eupatorium adenophorum was the most violent and the purified LA-I toxin took the second place , and purified LA-II was much feebler .

紫茎泽兰素A对乙酰胆碱酯酶和Na-K-ATP酶的抑制作用是其导致蚜虫死亡的重要原因。

Tests also showed that Eupatorin A can inhibit the activity of AchE and Na-K-ATPase of the cotton aphids in vitro and in vivo . The inhibition was deepened with the bigger concentration of Eupatorin A and the longer toxic time .
