Compared with control plant growing in NS with phenanthrene alone, phenanthrene level in cucumber root decreased but above-ground phenanthrene level remained un-affected in NS with phenanthrene and Tween 80 at supra-CMC.

在含有菲和表面活性剂的营养液中培养黄瓜幼苗时，大于CMC的Tween 80处理使黄瓜根中菲含量下降，而地上部分菲含量受营养液中表面活性剂的影响不显著。

The results showed Agri-Terra (the dosage of application 1.0%~3.0% at 40mL per plant) was extremely effective against Meloidogyne incognita infection to cucumber. It significantly reduced cucumber root gall index and the number of second stage larvae in soil.

结果表明，Agri-Terra能减少南方根结线虫对黄瓜的侵染，显著地降低黄瓜根结指数和土壤中二龄幼虫的数量。

D after setting, the fresh root weight and dry root weight of IC3 were 8.63 and 0.35g, respectively, which increased by 9.30% and 5.67% compared with the control (without plastic pipe and plastic pot) and the difference reached significant level; CO2 concentration of root rhizosphere of cucumber on IC3 was 0.309% at 13:00, which reduced by 29.4% compared with the control.

定植后13d， IC3处理黄瓜的根鲜重、根干重依次为8.63， 0.35g，比对照分别增加了9.30%和5.67%，差异达显著水平；在13：00时，IC3处理黄瓜根际CO2含量为0.309%，比对照降低了29.4%。

To biologically control it, we have attempted to screen antagonistic bacteria against fusarium wilt disease strain from seedling rhizosphere of cucumber.

取得的主要结果如下： 1 从黄瓜根围土壤中，共分离获得100多株对枯萎病病原菌有拮抗活性的细菌菌株。

Virulence Difference of Biocontrol Bacteria J352 to Diffenent Nematodes WANG Yuan-yuan, DUAN Yu-xi, WANG Xu, CHEN Li-jie (Plant Nematology Laboratory, Shenyang Agricultural University, Shenyang 110161, China) Abstract: A bacterium J352 with antagonism to several pathogens was obtained from rhizosphere of cucumber. The effects to different nematodes were test by strain J352 fermentation broth with different concentration.

生防细菌J352对不同种类线虫的毒力差异王媛媛，段玉玺，王旭，陈立杰(沈阳农业大学植物保护学院线虫学研究室，沈阳 110161)摘要：从黄瓜根际分离获得一株对多种病原真菌有较强抑制作用的细菌，用该细菌不同浓度的发酵液测定了对4种线虫的作用。

According to sequence cluster analysis of the the tested samples, it indicates that the gene distance of RKN-9, RKN-8, RKN-21, RKN-11, RKN-18 , RKN-20, RKN-17, RKN-22, RKN-23, RKN-24 and RKN-25 to Meloidogyne incognita and Meloidogyne arenaria was very close with homology of 100% and 99%, respectively.

根据25个根结线虫种群序列比对分析和聚类分析可知，河北廊坊的番茄根结线虫、安徽宿州的黄瓜和番茄根结线虫、安徽太和的桔梗根结线虫、安徽和县的番茄根结线虫、浙江杭州的黄瓜根结线虫、四川成都的番茄根结线虫、安徽泗县的黄瓜根结线虫和中国农业大学四个不同番茄品种上的根结线虫的序列之间同源性为100％；它们与花生根结线虫和南方根结线虫(M.incognita)的遗传距离最近，序列同源性分别达到100％和99％。

These results indicated that Agri-terra could be a prospective nematocide for cucumber root-knot nematodes control.

Agri-Terra可有效地控制黄瓜根结线虫的危害，有较高的推广应用价值。

Exposure to 14℃didnt change the values of Valt and Vcyt in figleaf gourd root systems.

同时，低根温也引起黄瓜根尖更多的细胞死亡，而在黑籽南瓜中未发现此现象。
