摘要

在有机氯农药污染的土壤中，细菌菌株对植物生长发育的生物增强作用一直是人们关注的焦点，但对睾酮单胞菌的影响知之甚少。采用经典方法进行调查。研究结果表明，睾酮单胞菌UCM B-400和b -401对土壤中的外源生物具有较高的破坏潜力，对植物发育也有积极作用。研究了在HCB污染和未污染土壤中添加雄性单胞菌UCM B-400和B-401对番茄植株生长发育的影响。睾酮单胞菌UCM B-400和B-401促进了光合活性和生物特征参数的提高，并增强了对密歇根键杆菌亚基等植物病原体的抗性。密歇根草UCM Ас-629(可达36%)和alternnaria alternata UCM F-16866(可达32%)睾酮单胞菌UCM B-400和B-401可以作为接种剂改善HCB负载土壤中植物的生长条件。

Potentially Beneficial Comamonas Testosteroni Bacteria for Plants Growing in HCB-Polluted Soil

The bioaugmantation effect of bacterial strains on plant development in organochlorine pesticides (OCP) polluted soil has been in the focus of attention, however there is little information about Comamonas testosteroni strains influence. The investigation was performed by classic methods. The results of the research showed that Comamonas testosteroni UCM B-400 and B-401has a high destroying potential to xenobiotics in the soil, and also has a positive effect on plant development. The tomato plants ability to develop under conditions with Comamonas testosteroni UCM B-400 and B-401 bioaugmentation in HCB - contaminated and uncontaminated soil were studied. Comamonas testosteroni UCM B-400 and B-401 promoted the increasing of photosynthetic activity, biometric parametrs and increase the resistance to phytopathogens, such as Clavibacter michiganensis subs. michiganensis UCM Ас-629 (up to 36%) and Alternaria alternata UCM F-16866 (up to 32%). Comamonas testosteroni UCM B-400 and B-401 can be used as an inoculant to improve plant development conditions in HCB load soils.
