Au concentrations in roots, seed and leaves of wheat seedlings of genotype Zlata in control variant and in plants treated with Au-based nanoparticles (Au-NPs).

Variant of Experiment	Au, µg g−1 Dry Weight
	Roots	Leaves	Seeds
Control	<0.05	<0.05	<0.05
Au-NPs	1.6 ± 0.1	0.28 ± 0.01	3.9 ± 0.2

In each variant of the treatment, 3 statistical repetitions were carried out. The experiment was repeated 2 times. Au-NPs concentration—10 µg mL⁻¹ (as concentrations causing the maximum effect on tolerance to low temperature).
