in soil
Results further revealed that ethylene accumulation in soil from these substrates caused a classic "triple" response in etiolated pea seedlings with different degrees of efficacy.
      
This study demonstrated that the presence of substrate(s) in soil may lead to increased ethylene concentration in the air of the soil, which may affect plant growth in a desired direction.
      
Interrelationships between yeast fungi and collembolans in soil
      
Development and relations of Fusarium culmorum and Pseudomonas fluorescens in soil
      
The development of Fusarium culmorum and Pseudomonas fluorescens in soil, and the relations between them, were studied using membrane filters containing the fungus, the bacterium, or both microorganisms; the filters were incubated in soil.
      
culmorum introduced in soil can develop as a saprotroph, with the formation of mycelium, macroconidia, and a small amount of chlamydospores.
      
culmorum mycelium in soil, but stimulated chlamydospore formation.
      
fluorescens was more pronounced in soil without additions and less pronounced in the case of introduction of glucose or cellulose.
      
Accumulation of 1-hydroxy-2-naphthoic acid in soil in the course of phenanthrene degradation by strain BS3702 (pBS1143) in a model system has been revealed.
      
The frequency of plasmid transfer in soil was 10-5-10-4 per donor cell.
      
The effects of different scenarios of carbon sequestration in soil on the amounts and activity of microbial biomass are discussed.
      
Factors Influencing the Long-term Corrosion of Bronze Artefacts in Soil
      
The investigation was undertaken to determine the main factors causing deterioration of bronze objects in soil by studying artefacts from archaeological excavations in progress.
      
The results are of importance for the understanding and estimation of long-term corrosion of bronze objects in soil.
      
The character and rate of the corrosion process can be predicted by comparing the metal potentials with the polarization curves recorded in soil electrolytes at pH values typical of the near-electrode soil layer.
      
A critical review of the modern concepts of the radionuclide speciation in soil is made.
      
It is shown that subdivision of radionuclides in soil into the water-soluble, exchangeable, mobile, and fixed species is not scientifically valid.
      
New experimental results show that Cs radionuclides exist in soil as ionic (molecular) species irrespective of the distance from the Chernobyl NPP.
      
X-ray Spectrometric Determination of Thorium in Soil Samples Using the (γ,n) Reaction
      
Joint determination of 238Pu, 239, 240Pu, 241Pu, and 90Sr in soil
