- Abstract
The impact method was used to collect airborne fungi in dry and rainy seasons for 4 times in different experimental sites (fields, sheds and storehouse) of the Xishuangbanna Tropical Rainforest Atmospheric Experiment Station. The quantity of fungi was calculated using a statistical method at different experimental sites in dry and rainy seasons. The fungal strains were identified by morphological characters combined with ITS1-5.8S-TIS2 or 26S rDNA D1/D2 region sequence analysis. The relationship between environmental factors and atmospheric fungi was preliminarily investigated using the SPSS and R software. The results showed that the concentration of airborne fungi was 2 200-4 300cfu/m3 in the atmosphere of Xishuangbanna Experiment Station, and 776 strains of fungi were isolated and classified into 34 genera and 52 species. The dominant species were Aspergillus minisclerotigenes, Cladosporium oxysporum, Clonostachys epichloe, Fusarium incarnatum, Leptosphaerulina chartarum, Paraconiothyrium estuarinum and Penicillium steckii. The fungal diversity in the atmospheric environment is rich but the communities and concentrations of fungi changed seasonally. The community structure of fungi varied significantly among the three experimental sites in different seasons. The important environmental factors which affected the structure of airborne fungal community were precipitation and atmospheric pressure.
