An impact of environmental parameters on atmospheric concentration of Cladosporiumover Bajra fields, at Beed

摘要

The incidence of the spores of Cladosporium Link ex. Fr. was recorded separately during exploration of airborne microbes over Bajra (Pennisetum typhoides Stapf. & Hubb.Var. Nirmal No.9.) fields for two kharif crop seasons during the years 2002 and 2003, using continuous Volumetric Tilak Air Sampler in order to estimate an impact of weather conditions on atmospheric concentration of spores of Cladosporium. The daily weather records of parameters like temperature, relative humidity, wind velocity and rainfall were maintained. The significance of the Cladosporium as aeroallergens is considered. The spores of Cladosporium Link ex.Fr. were observed in the atmosphere round the year. This spore type was found to be the most dominant as compared to other spore types in order of their concentration. The spores of Cladosporium being universally dominant, during the present investigation occured in clumps. Reports from different centres from India and abroad about the occurence of these spores in air clearlyrevealed the fact that these spores occur during kharif seasons with high humidity and rainfall, moderate wind velocity and low temperature. The present paper deals with the relationship between incidence of Cladosporium spores and prevailing weather conditions.
