dc.description.abstract | The combination of reproductive success with high stress tolerance (through
osmotic adjustment and antioxidants) is essential for invasion success, particularly in
stressful environments in the frame of global change.Antioxidant capacity could be a
possible marker of adaptation to variable environmental conditions, since change in
amount of antioxidants represents one of the first responses to various environmental
stimuli. Among investigated ragweeds, I. xanthifolia leaves had more pronounced
guaiacol-peroxidase (GPx) activity (2.5- to 9.7-fold) than A. artemisiifolia and A.
trifida. A. artemisiifolia and I. xanthifolia leaves have similar reduced glutathione
(GSH) content (13.05 μmol g-1 fr. w.), while A. trifida had 1.3-fold lower GSH
concentration. However, superoxide-dismutase (SOD) activity was invariable in all
investigated plants (234.1-247.5 U g-1 fr. w.). The highest content of total phenolics,
tannins, flavonoids and proanthocyanidins were detected in A. trifida leaves (up to
3.7-fold the amount of the others). According to antioxidant activity (O2˙-, ˙OH and
DPPH-scavenging tests), investigated ragweed species could be presented in a scale:
A. trifida > I. xanthifolia > A. artemisiifolia. Accumulation of non-enzymatic
antioxidants and lower content of GSH point to different oxidative stress avoidance
strategies of A. trifida when compared to A. artemisiifolia and I. xanthifolia within the
same environmental conditions. | sr |
