Abstract:
Taking five peony varieties (‘Cailouzi’‘Da′ou’‘Fotouqing’‘Huangguan’ and ‘Xingguangyicai’) as test materials,an artificial simulated low-temperature stress (-35--15 ℃) method was used to investigate changes in relative electrical conductivity,semi-lethal temperature (LT50),malondialdehyde (MDA),proline (Pro),soluble sugar,and soluble protein contents,as well as superoxide dismutase (SOD) and peroxidase (POD) activities after treatment.The membership function method was employed to comprehensively evaluate their cold resistance,in order to provide reference for cold-resistant peony breeding and regional cultivation.The results showed that,peony ‘Xingguangyicai’ had the lowest (LT50),the smallest increase in relative electrical conductivity at -35 ℃,a decrease in MDA content after -25 ℃ treatment,the strongest cell membrane stability,and the highest soluble sugar content and SOD activity at -30 ℃,effectively clearing ROS-induced cell damage.Peony ‘Huangguan’ had an LT50 of -20.069 ℃ and an electrical conductivity of 72.80% after -35 ℃ treatment showed moderate membrane damage.Its soluble protein content and SOD activity reached maximum values at -35 ℃ treatment,significantly higher than other varieties,but its POD activity dropped to the lowest value (3.586 U·min-1·g-1) at -25 ℃,leading to intracellular ROS accumulation.Peony ‘Fotouqing’ had the highest LT50,with relative electrical conductivity reaching 74.29% after -35 ℃ treatment,indicated the most severe membrane damage.MDA content and POD activity generally showed a decreasing trend with decreasing treatment temperature,and POD activity at -20 ℃ was significantly lower than other treatments.Membership function analysis showed that peony ‘Xingguangyicai’ had the strongest cold resistance,while peony ‘Fotouqing’ had the weakest.Combined evaluation based on(LT50) and membership function indicated that the cold resistance order of the five peony varieties was ‘Xingguangyicai’>‘Cailouzi’>‘Huangguan’>‘Da′ou’>‘Fotouqing’.These varieties enhanced cold resistance by improving cell membrane stability,accumulating osmotic adjustment substances,and activating the antioxidant system.
