1. Potential of soil fumigation with mustard essential oil to substitute biofumigation by cruciferous plant species
Soil fumigation with the synthetic essential oil of mustard (93% allyl isothiocyanate) (EOM) was evaluated as a substitute of bio-fumigation with cruciferous plant species, using Sclerotium rolfsii and Sclerotinia sclerotiorum as test pathogens, together with its non-target effect on the general population of soil microorganisms. The mortality of the sclerot

2. Biomassa microbiana do solo.
ABSTRACT: The microbial biomass, respiration and their derivative indexes are proposed as indicators of the state and changes of the soil organic matter. This document presents basic information about these indicators and the two methodologies most used for C-microbial biomass determinations, the fumigation-incubation and the fumigation-extraction methods.

3. AvaliaÃÃo fungitÃxica e caracterizaÃÃo quÃmica dos Ãleos essenciais e extratos obtidos apÃs diferentes processos de extraÃÃo de Cipà Vick (Tanaecium Nocturnum) e JoÃo Brandim (Piper Piscatorum) / Evaluation of fungitoxic activity and chemical characterization of the essential oils obtained after different processes of extraction of cipà vick (Tanaecium nocturnum) and joÃo-brandim (Piper piscatorum).
The chemical characterization by IR, GC-MS and GC-FID of essential oils and extracts obtained from Piper piscatorum and Tanaecium nocturnum, plant species native to the state of Acre, by different extraction processes and the evaluation of the toxicity to Aspergillus flavus were performed. The study involved four experiments. In the first, the efficiency of

4. Atividade e diversidade da biomassa microbiana em diferentes sistemas de manejo do solo e de culturas no norte do Estado do Parana / Activity and diversity of microbial biomass under different soil and crop management systems in the north of the state of Parana (Brazil)
The microbial biomass carbon (MB-C) and nitrogen (MB-N), basal respiration and metabolic quotient (qCO2) were evaluated in a Rhodic Eutrudox of the North Region of the State of Paraná under different soil and crop management systems. The experimental area was established in 1988/1989 at the experimental station of Embrapa Soja, Londrina, Paraná, and consis

5. Ethylene, Ethane, Acetaldehyde, and Ethanol Production By Plants under Stress 1
Red pine (Pinus resinosa Ait.) and paper birch (Betula papyrifera Marsh.) seedlings exposed to sulfur dioxide produced acetaldehyde and ethanol, and exhibited increased production of ethylene and ethane. Gas chromatographic measurement of head space gas from incubation tubes containing leaves or seedlings was a simple method of simultaneously measuring all f
