CLAIRO Zoom-in 2: Plant hormones help planted trees withstand unfavourable environmental conditions in Ostrava
Not surprisingly, the newly planted greenery in Ostrava is exposed to multiple environmental stressors, especially in one of the plots that is located at the edge of a slag deposit area in the Bartovice neighbourhood. At this site the soil has very poor quality. It is dry, lacking nutrients and is contaminated by heavy metals. On top of this, plants need also to cope here with poor air quality.
With the aim to increase the resistance of the new vegetation to the harsh local environmental conditions, the plants are treated by the Palacky University Olomouc with biostimulants fortified by cytokinins, a class of plant hormones. Although plant hormones are usually found in very small concentrations, they have robust effects on plant growth and development. Cytokinis, on top of regulating a number of important physiological processes, help the plants overcome environmental stress.
