Wild marjoram is the most widely distributed species among the genus Origanum L. and is valued as an aromatic and medicinal crop. It is commonly marketed as a fresh herb in pots for culinary purposes. Combined stress factors affecting plants within the producer-consumer chain can significantly change their chemical composition. The aim of the study was to evaluate the effects of chilling and light stress applied to young plants of wild marjoram (Origanum vulgare L.) on selected bioactive compounds. Potted plants meeting market standards were subjected to temperature and light regimes: (a) 5°C, light irradiance od 0, 100 and 250 µmol m2 s-1 for 7 days, in phytotron chambers. Analyses proved a significant influence of the stress factors applied on dry matter, soluble sugars, photosynthetic pigments and compounds associated with stress acclimation. The general effect observed was an increase in most bioactive compounds, with the exception of pigments, in potted wild marjoram plants subjected to chilling in conditions of limited light irradiance (100 µmol m2 s-1 ). In chilling conditions, a lack of light and irradiance at the level of 250 µmol m2 s-1 mitigated the stress response but simultaneously decreased the biological quality of plants. The combined application of specified chilling and light levels may increase, by initiating mild stress, the health-promoting value of potted wild marjoram dedicated as a product for the fresh market.
