Resumen
En hojas de Morus alba L. se evaluó la variación del contenido de sólidos en suspensión; durante un ciclo vegetativo (primavera, verano y fines de otoño), en el área urbana y suburbana de San Juan (Argentina). El estudio se realizó en San Juan muestreándose 40 árboles al azar. Los datos obtenidos se analizaron mediante ANOVA. El área foliar media externa representó el 52,1 ± 13,4 % en urbano y el 55,2 ± 9,2 % en suburbano. No se encontraron diferencias estadísticas en las partículas depositadas en la parte externa e interna de la copa. Las partículas 2 depositadas por cm de follaje no difieren estadísticamente entre urbano y suburbano. Teniendo en cuenta el censo forestal, el área 2 foliar media y los sólidos/cm , se depositaron en total 9.9 kg en primavera y 295.7 kg en otoño de sólidos.
In leaves of Morus alba was analyzed the variation in air particle deposition, during a complete vegetative cycle (spring, summer and end of autumn), in urban and suburban area of San Juan (Argentina). The study was made in San Juan sampling 40 trees randomly selected. Data obtained were statistically analyzed using the ANOVA test. The treetop mean external foliar area represents 52.1 ± 13.4 % in urban and 55.2 ± 9.2 % in suburban areas. No statistical differences were found in particles accumulated in internal and external sectors of the treetop. 2 Accumulated particles by cm of foliage did not differ statistically between urban and suburban area. Taking into account the forest 2 census, the mean foliage area, and the particulate/cm , total solids deposited were 9.9 kg (spring) and 295.7 kg (fall).
