Abstract

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.
