    Sequential response of sage antioxidant metabolism to chilling treatment

  • Popis výsledku v původním jazyce

    Chilling influences the growth and metabolism of plants. The physiological response and acclimatization of genotypes in relation to stress stimulus can be different. Two sage cultivars: &apos;Icterina&apos; and &apos;Purpurascens&apos; were subjected to 4 oC and 18 oC (control), and sampled between the 5th and 14th day of the treatment. Ascorbate peroxidase (APX) activity was up-regulated in chilled &apos;Purpurascens&apos; on the 14th day, while guaiacol peroxidase (GPX) activity increased on the 10th and 12th day in relation to the control. GPX activity of the control &apos;Icterina&apos; was frequently higher than chilled plants, and chilling did not affect APX activity of that cultivar. Catalase activity remained stable in both sage cultivars. Chilled &apos;Purpurascens&apos; showed a significant increase in total phenolics contents on the 5th, 7th, and 12th day and in total antioxidant capacity on the 5th and 10th day as compared to the control for respective sampling days. Higher malondialdehyde content was found in chilled plants on the 12th, or 14th day, differences reached 26-28% of the controls. Chilling caused significant decrease in dry matter content. The stress response was more stable and effective in &apos;Icterina&apos;, while more dynamic changes were found for &apos;Purpurascens&apos;. Based on our results, we propose to use &apos;Purpurascens&apos; for targeted stress-induced studies and &apos;Icterina&apos; for field applications.
