Resumen:
To evaluate the physiological response of Tillandsia
capillaris Ruiz & Pav. f. capillaris, T. recurvata L.,
and T. tricholepis Baker to different air pollution sources,
epiphyte samples were collected from a noncontaminated
area in the province of Co´rdoba (Argentina) and transplanted
to a control site as well as three areas categorized
according to the presence of agricultural, urban, and
industrial (metallurgical and metal-mechanical) emission
sources. A foliar damage index (FDI) was calculated with
the physiological parameters chlorophyll a, chlorophyll b,
malondialdehyde (MDA), hydroperoxyconjugated dienes,
sulfur (S) content, and dry weight-to-fresh weight ratio. In
addition, electrical conductivity (E-cond), relative water
content (RWC), dehydration kinetics (Kin-H2O), total
phenols (T-phen), soluble proteins (S-prot), and activities
of superoxide dismutase (SOD), catalase (CAT), and
ascorbate peroxidase were determined. The parameters
E-cond, FDI, SOD, RWC, and Kin-H2O can serve as
suitable indicators of agricultural air pollution for T. tricholepisTillandsia
