Abstract

This study evaluated sage (Salvia officinalis L.) genotypes (cultivars: ‘Berggarten’, ‘Icterina’, ‘Purpurascens’, ‘Tricolor’, local Czech accessions from the Lednice region, South Moravia: ‘LDN-1’ and ‘LDN-2’) subjected to chilling (4 °C, 2 weeks, 18 °C ‒ control) for comparison of antioxidant defence systems. Chilling caused the most significant increase in the peroxidase activity in ‘Purpurascens’ and ‘Tricolor’, by 108.5% and 15.7%, respectively, while the catalase was unaffected by the low temperature. The phenolics increased in ‘Purpurascens’ and ‘LDN-1’ by 17.2% and 18.1%, respectively, and decreased in ‘LDN-2’ and ‘Tricolor’, by 10.6% and 11.7%, respectively, as a result of the chilling. In the sage treated with chilling, the scavenging of 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH•) was higher (by 3%, on average), especially in ‘Berggarten’, ‘Icterina’, and ‘Purpurascens’, than in the control. However, the chilled ‘LDN-2’ and ‘Tricolor’ showed lower antioxidant∙ activity in comparison to the control. The malondialdehyde remained stable or was higher in the control, with the only exception being ‘LDN-1’, where its content increased by 11.4% in the chilled sage. In most genotypes, the content of the dry weight increased in the chilled plants by 9.4% on average. The responses of ‘Icterina’ and ‘Purpurascens’ to the low temperature was the most significant, but resulted from different physiological mechanisms. ‘Purpurascens’ showed the highest increase in the peroxidase activity due to the chilling, while the highest increase in the antioxidant activity was observed for ‘Icterina’.

鼠尾草基因型对低温的生理生化反应
本研究评估了经过冷藏(4°C,2周,18°C对照)的鼠尾草基因型(品种:“Berggarten”,“Icterina”,“Purpurascens”,“Tricolor”,来自南摩拉维亚Lednice地区的捷克当地材料:“LDN-1”和“LDN-2”),以比较抗氧化防御系统。低温处理使‘Purpurascens’和‘Tricolor’的过氧化物酶活性分别提高了108.5%和15.7%,而过氧化氢酶不受低温影响。低温处理使‘紫檀’和‘LDN-1’的酚类物质分别增加17.2%和18.1%,‘LDN-2’和‘三色’的酚组分分别减少10.6%和11.7%。在用冷冻处理的鼠尾草中,对2,2-二苯基-1-苦基肼基自由基(DPPH•)的清除率高于对照(平均3%),尤其是在“Berggarten”、“Icterina”和“Purpurascens”中。然而,与对照相比,冷冻的“LDN-2”和“三色”显示出较低的抗氧化活性。对照组的丙二醛保持稳定或更高,唯一的例外是“LDN-1”,其含量在冷冻鼠尾草中增加了11.4%。在大多数基因型中,冷冻植物的干重含量平均增加9.4%。“Icterina”和“Purpurascens”对低温的反应最为显著,但其生理机制不同Purpurascens的过氧化物酶活性因冷藏而增加最多,而Icterina的抗氧化活性增加最多。
