Basidiospores are a significant component of the airspora and have been implicated in both allergic rhinitis and asthma. Identification of these spores is hindered by the lack of available reference material. The preparation of reference slides from local specimens is necessary. Collecting procedures and a simple method for making permanent reference slides are presented.
Over the past five winters atmospheric Juniperus (cedar) pollen was collected in December and January in Tulsa, Oklahoma. Evidence from phenology, wind patterns, and plant distribution indicate that this pollen is from Juniperus ashei (mountain cedar) populations in south central Oklahoma and possibly Texas. The presence of this highly allergenic pollen in the Tulsa atmosphere indicates the potential for allergy problems among sensitive individuals in northeast Oklahoma.
A Rocky Mountain subalpine environment was sampled for allergenic pollen and mold spores during three growing seasons (1981-1983) using a Rotorod sampler. Pollen levels were generally low until late in the season while mold spores were present in higher levels throughout the sampling period.
Many common landscaping plants produce allergenic pollen. Hay fever patients can reduce their exposure to aeroallergens by selecting non-allergenic species for yards, lawns and streets. The plants listed here are non-allergenic (hypo-allergenic) and possess characteristics desired for landscaping. Categories described include trees, shrubs, vines, perennial herbs and grasses.
Levels of atmospheric Ambrosia (ragweed) pollen in the urban environment of Tulsa, Oklahoma, were determined using a Rotorod sampler. The data, representing the distinctly different growing seasons of 1980 and 1981, suggest it may be possible to predict pollen season levels based upon early summer weather patterns.
More than 181 species of Oklahoma hay fever plants were identified. These are listed with their relative allergenicity and distribution within six major botanical zones of the state.
