- Abstract:
- In order to prove the protective effect of 8 kinds of cold-proof measures,strengthen the overwintering protection ability of sweet cherry in Ili area of Xinjiang and promote the development of local forestry and fruit farming.Under the protection of different cold-proof measures during the wintering period，soluble protein content，superoxide dismutase activity，peroxidase activity，and catalase activity were measured to judge the pros and cons of the protective effect of various cold-proof measures by the adoption of the subordinate function method with 2-year-old sweet cherry saplings as test materials.The results showed that soluble protein and protective enzyme activities were positively correlated with the overwintering of sweet cherry，and increased first and then decreased with the decrease of temperature.Under the hilling up+straw screens treatments，the content of soluble protein was 33.75 mg·g-1 when the temperature was -22 ℃，which was the highest and had significant difference with the control group,and then hilling up+felt.Among the three kinds of protective enzymes，the activities of superoxide dismutase，peroxidase and catalase in hilling up+straw screens were the highest，which were 114.98 U·g-1,45.17 U·g-1·min-1and 403.75 U·g-1·min-1 and had significant difference with control group，followed by hilling up treatments.The result shows that the protection effect of each cold-proof measure was list as follow,hilling up+straw screens>hilling up>hilling up+felt>straw screens>felt>plastic membrane>white paint>limewater>CK.
