Occupational and Environmental Medicine 1995;52:575-580 Oilseed rape and bronchial reactivity
Objectives-To investigate atopy and changes in symptoms, peak flow rate, and bronchial reactivity in people complaining of symptoms during the oilseed rape flowering season. Methods-37 people who had given positive answers to questions about the presence of symptoms in relation to the flowering season of oilseed rape and 24 controls with no such symptoms were studied, although not all took part...
متن کاملIdentification of Drought Tolerant Oilseed Rape Genotypes using Multivariate Analysis
Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...
متن کاملOilseed rape and seasonal symptoms: epidemiological and environmental studies.
BACKGROUND There is widespread concern that the cultivation of oilseed rape leads to seasonal epidemics of respiratory symptoms in populations living in the neighbourhood, and it has been suggested that the plant is a potent allergen. A study was therefore undertaken to determine the prevalence of seasonal symptoms in rural populations close to and far from areas of oilseed rape cultivation, an...
متن کاملInterrelationships among oilseed rape (Brassica napus L.) grain yield and weed growth under different nitrogen levels
Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...
متن کاملSources and sinks of ammonia within an oilseed rape canopy
Within-canopy profiles of ammonia (NH3) and measurements of the canopy turbulence characteristics were used to calculate the vertical source/sink density profile of NH3 and sensible heat in a mature oilseed rape (Brassica napus) canopy. For the analysis, the inverse Lagrangian technique (ILT) based on localized near-field theory was used. Turbulence was measured with a standard ultrasonic anemo...
