Effect of copper on ornamental plants Agrostis stolonifera L., Centaurea cyanus L., Godetia grandiflora Lindl

Ornamental plants are widely used in horticulture and urban greening. However, when plants are used in urban greening, it is necessary to select varieties with increased tolerance to urban conditions. Copper is one of the most toxic metals to plants, so the assessment of plant resistance to copper is important for urban environments. High sensitivity of the studied plants to copper was shown. Godetia grandiflora is the most resistant to copper among the species studied. Agrostis stolonifera and Centaurea cyanus had comparable resistance to copper. The effect of copper on calli of Agrostis stolonifera was also studied.
