Effect Of 1-MCP And Ozone Treatment On Physiology And Quality Of Fig During The Storage

Fig fruit(Ficus carica), a special fruit and inartificial plant medication, and had preferable nutrition value and medicine value. As an upper economy value fruit, showed that high water content and faultiness protect function and easily damnification of pericarp during storage. Therefore, fig was difficult preserved and transported after post-harvest, and stored 1-2d at normal temperature. So it is important to study its storage and preserve technology, which provided the theoretical and practical technic for the business storage of fig fruit. The effects of different concentrations of 1-MCP and ozone on physiology quality of fig fruit. The main results were as follows:1. The results of quality index study showed that fig was treated with different concentrations (1.0, 1.5 and 2.0μL/L) 1-MCP had slower loss of firmness; reduced the losing of reducing sugar, titratable acid and Vc; decreased weight loss and rotten rate. The optimum concentration of 1-MCP was 1.5μL/L under condition of cold storage for 25d, being significantly lower than of control.2. The results of physiology index study showed that fig was treated with different concentrations (1.0, 1.5 and 2.0μL/L) 1-MCP had inhibited respiration rate and ethylene production, postponed fastigium appearance of respiration and ethylene production and decreased fastigium value; improved activities of CAT, POD and SOD; and inhibited MDA content and the increasing of relative electric conductivity. The optimum concentration of 1-MCP was 1.5μL/L under condition of cold storage for 25d.3. The results of quality index study showed that fig was treated with different concentrations (4.18 mg/m3, 8.56 mg/m3, 12.84 mg/m3 and 17.12 mg/m3) ozone had slower loss of firmness; reduced the losing of reducing sugar, titratable acid and Vc; decreased weight loss and rotten rate. The optimum concentration of ozone was 12.84 mg/m3 under condition of cold storage for 25d, being significantly lower than of control.4. The results of physiology index study showed that fig was treated with different concentrations (4.18 mg/m3, 8.56 mg/m3, 12.84 mg/m3 and 17.12 mg/m3) ozone had inhibited respiration rate and ethylene production, postponed fastigium appearance of respiration and ethylene production and decreased fastigium value; improved activities of CAT, POD and SOD; and inhibited MDA content and the increasing of relative electric conductivity. The optimum concentration of ozone was 12.84 mg/m3 under condition of cold storage for 25d.
