摘要: Summary. Treating seedling roots of several plant species with cultures Azotobacter paspali changed growth and development significantly increased weight leaves roots; effects were probably caused by regulators. Culture supernatant fluids contained indolyl-3-acetic acid, at least 3 gibberellins 2 cytokinins. The added inoculum A. survived in rhizospheres for only a few weeks no nitrogen was fixed the root zone young Paspalum notatum, grass which is associated.
