Resumen:
A diagnostic study was done on Ligustrum lucidumAit. f. tricolor (Rehd.) Rehd. in relation to atmosphericpollutants in Co´ rdoba city, Argentina. The study area receivesregional pollutants and was categorized taking intoaccount traffic level, industrial density, type of industry, locationof the sample point in relation to the street corner, treelesscondition, and topographic level. Dried weight/freshweight ratio (DW/FW) and specific leaf area (SLA) were calculated,and concentrations of chlorophylls, carotenoids,total sulfur, soluble proteins, malondialdehyde (MDA), andhydroperoxy conjugated dienes (HPCD) were determined inleaf samples. Sulfur content correlates positively with trafficdensity and SLA correlates negatively with some combinationsof the categorical variables; MDA correlates positivelywith topographic level and total protein concentration correlatesnegatively with treeless condition. On the basis of ourresults, traffic, location of trees, type of industry, situation of atree with respect to others, and topographic level are theenvironmental variables to bear in mind when selectinganalogous sampling points in a passive monitoring program.An approximation to predict tree injury may be obtained bymeasuring DW/FW ratio, proteins, pigments, HPCD, andMDA as they are responsible for the major variability of data.
