Nickel-induced biphasic regulation of morpho-physiological, biochemical, and essential oil traits in drought-stressed Fumaria parviflora Lam.
Nickel (Ni) acts as an essential micronutrient at low concentrations but induces toxicity when accumulated excessively. Drought stress likewise restricts plant growth and secondary metabolism in medicinal plants. This study investigated the single and interactive effects of foliar-applied Ni and drought stress on growt...
