Resumen:
We evaluated the qualitative and quantitative presence of airborne spores and recording temperature and light intensity in the absence and presence of ornamental plants without the latter were assessed during periods of three weeks from March 12 to 16 th, April 16 th to 20 th and from May 14 th to 18 th, 2007 under three indoor environments in the Colegio de Postgraduados Campus Montecillo, Texcoco, estado de Mexico. An Andersen sampler one stage for fungal spore and a data logger Pendant® series (Onset© Co.) for registering temperature and light were used. Fungal identification was performed to the genus level with and without plants. Alternaria, Cladosporium, Epiccocum, Fusarium and Penicillium were the predominant genera obtained; but Aspergillus niger and A. candidus were also found. Aerial spore levels decreased by 60% in plants presence and temperature increased between 2 and 3 °C in the three rooms sampled. No significant differences for light intensity were observed by plants presence. There was a clear behaviour between the intensity of light and the position of the indoor environments. The results showed that in the presence of plants and increasing the indoor temperature, the concentration of fungi in the air decreased.
