Sažetak
Thermal stress such as cold stress is a serious threat to the sustainability because it can lead to major crop losses which can limit the availability of vegetables on the market and have economic consequences. In our project we hypothesize that we can begin to address a problem of low temperature stress by investigating how kale (Brassica oleracea L. var. acephala), which is highly resistant to low temperature, reacts to low temperature stress. In controlled laboratory conditions seedlings were exposed to chilling (8°C) and freezing (-8°C) temperature and changes in physiological, molecular and biochemical responses were evaluated in comparison with the control (21°C). Prolin increased with the temperature and shown to be good marker for low temperature stress. Seedling at chilling (8°C) temperature had shorter roots and longer hypocotyls. Phenolic compounds were not significantly different at chilling (8°C) temperature but decreased at freezing temperature. Glucosinolates content decreased in parallel with the temperature. Further, we will do detailed metabolomic analysis in order to see the role of specialized metabolites in low temperature stress tolerance of Brassica oleracea var. acephala.
