摘要: 为了探讨冬季日光温室根区温度对辣椒质膜透性、保护酶活性以及渗透调节物质的影响,以辣椒品种长金、迅驰37-74和运驰37-82为试验材料,对高温(20~22 ℃)、中温(16~18 ℃)、低温(11~16 ℃),其中以低温为对照,3个梯度温度处理下辣椒成株期超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性,脯氨酸(Pro)、丙二醛(MDA)含量和电导率(EC)进行了测定。结果表明:随着根区温度的升高,丙二醛(MDA)和电导率(EC)连续降低为正常值,中温(16~18 ℃)、高温(20~22 ℃)与低温(11~16 ℃)处理间存在显著差异(P<0.05);在高温、中温处理下地下部超氧化物歧化酶(SOD)、过氧化物酶(POD)活性极显著高于低温(CK)处理(P<0.01),高温、中温处理下地上部过氧化物酶(POD)、过氧化氢酶(CAT)活性极显著高于低温(CK)处理。相关分析结果显示,地上部超氧化物歧化酶(SOD)与地下部过氧化物酶(POD)、地上部过氧化物酶(POD)与地下部过氧化物酶(POD)间均极显著正相关(r=1.000)。表明中温处理(16~18 ℃)能保证辣椒越冬栽培,植株具备较强的活性氧清除能力;低温在延长条件下,根部细胞有了主动调节能力。

Abstract: In order to explore the sunlight greenhouse root zone temperature in the winter stress on the membrane permeability,the protective enzyme activity and osmolyte in pepper,we comparatively studied three treatments (20-22 ℃,16-18 ℃,11-16 ℃),the activities of superoxede-dismutase(SOD),peroxidase(POD),catalase (CAT),proline(Pro),and malondialdehyde(MDA),and the electrolytic permeability contents were determined by using Changjin,Xunchi 37-74 and Yunchi 37-82 in pepper adult stage.The root zone of the winter greenhouse temperature of capsanthin membrane permeability and protective enzyme activity and the influence of the osmotic regulation substances,with long golden pepper varieties,centrino 37-74 and chi 37-82 as the research material,the high temperature (20-22 ℃),medium temperature (16-18 ℃) and low temperature (11-16 ℃) under three gradient temperature processing pepper into plant phase of superoxide dismutase (SOD),peroxidase (POD) and catalase (CAT) activity and proline (Pro),malondialdehyde (MDA) content and electric conductivity (EC) were determined.The results showed that malondialdehyde (MDA) and conductivity (EC) continuously decreased to normal values with the increase of the root temperature,and there were significant differences (P<0.05) between medium temperature (16-18 ℃),high temperature (20-22 ℃) and low temperature (11-16 ℃).The activity of superoxide dismutase (SOD) and peroxidase (POD) in the lower part of the ground was significantly higher than that in the lower part of the ground (CK) (P<0.01),and the activity of peroxidase (POD) and catalase (CAT) in the upper part of the ground was significantly higher than that in the lower part of the ground(CK).The correlation analysis results showed that the superoxide dismutase (SOD) in the aboveground part was significantly positively correlated with peroxidase (POD) in the underground part,peroxidase (POD) in the aboveground part and peroxidase (POD) in the underground part (r=1.000).The results showed that the medium temperature treatment (16-18 ℃) can ensure the pepper overwintering culture,and the plants have strong reactive oxygen scavenging ability.Under the condition of prolonged hypothermia,the root cells have the ability of active regulation.
