The Fluctuations Of Airborne Fungal Components In Western Romania, Nicoleta Ianovici
The Fluctuations Of Airborne Fungal Components In Western Romania, Nicoleta Ianovici
Turkish Journal of Botany
Outdoor regional concentrations of airborne fungal spores and fungal fragments were measured using the 7-day Lanzoni sampler. The daily and intradiurnal fluctuations recorded during the monitored period have been studied. The multiple regression analysis was performed in order to determine how much of the total variance in these concentrations could be explained by meteorological parameters. Daytime periodicity (statistically significant) was established only in a few cases. As the relative importance of the weather factors varied, they could not be ranked according to their effect.
