- •
Exogenous SA as drought-ameliorating agent were studied in Impatiens walleriana.
- •
PEG-induced negative effects on plant growth and physiology were counteracted by SA.
- •
PEG treatment caused, while SA ameliorated oxidative stress in I. walleriana.
- •
PEG and SA had opposing effects on the activity of antioxidative enzymes.
- •
SA may be used for drought protection of I. walleriana with no negative effects.
