Effect of atmospheric dust deposition on leaf chlorophyll fluorescence parameters of cow- tail shrubs (Smirnovia iranica): A case study (Kashan region), Iran

Smirnovia iranica, a native valuable woody species from Fabaceae, is an adaptable plant of central sandy areas of Iran. Changes in chlorophyll fluorescence and photosynthetic pigments characteristics were analyzed in the course of dust accumulation including DDM, DDJn and DDJl, respectively. The results obtained from analysis of variance indicated that there was a significant difference among different dust loading months of S. iranica in terms of the mentioned characteristics.
