Responses of Artemisia annua L. to lead and salt-induced oxidative stress
Abstract The Artemisia annua L. plants were subjected separately to NaCl (0–160 mM) and lead acetate (0–500 μM) at the age of 90 days (S1 treatment) and 120 days (S2 treatment). The treated plantsExpand

Zinc-Induced Changes in Morpho-Physiological and Biochemical Parameters in Artemisia annua
Responses of Artemisia annua to different concentrations of zinc [50, 100, 200, 300 and 400 μg g−1(soil dry mass)] were studied during plant ontogeny. Total leaf area, dry mass of leaves, length andExpand
