Introduction Forest-steppe is a climatically conditioned ecotone vegetation type, which comprises a natural, dynamic mosaic of steppe and forest communities (Mala 2016 and references therein). The main climatic condition of the forest-steppe zone is a neutral water balance, i.e., approximate equality of annual precipitation and evaporation, with annual cycles of wet and dry periods (Walter and Breckle 1994, Erdős et al. 2018).

4. Discussion 4.1. Chilling from the Kale’s Perspective—Change of Glucosinolate Pattern in Cold-Treated Kale Evaluating the influence of cold temperatures on glucosinolate levels in the leaves of different kale cultivars was made possible by quantifying seven major glucosinolates via HPLC-ESI-MS. Based on the results, curly kale “Frostara” reacts to cold-temperature exposure with an induction of GR production by approx. 85% ().
