- Abstract
This research aimed to evaluate the interference of the wood used in the boxes building, which the name are bins, used in the commercial storage, under the 1-metylcyclopropene (1-MCP) doses efficiency applied in 'Royal Gala' apples. The evaluated treatments were: control (without 1-MCP and without wood); 1-MCP (625nL L-1); 1-MCP (625nL L-1) + eucalyptus wood (Eucaliptus sp); 1-MCP (625nL L-1) + cedrinho wood (Erisma uncinatum Warm); 1-MCP (1.250nL L-1); 1-MCP (1.250nL L-1) + eucalyptus wood and 1-MCP (1.250nL L-1) + cedrinho wood. After four months of cold storage at 0,5°C and more seven days at 20°C, there was no decrease in the fruits quality that were treated with 1-MCP and stored on the presence and absence of wood, which showed that eucalyptus and cedrinho wood don't absorb 1-MCP to the point of influencing the product efficiency. The activity of the ACC oxidase, ethylene synthesis, respiration, flesh firmness and skin color didn't differ among the apples treated with 1-MCP and stored in the presence or absence of wood used in the bins building. There also was no difference among the doses of 1.250nL L-1 and 625nL L-1 1-MCP in the fruit maturation. In conclusion, the two kinds of wood used in the boxes building, which are used for the apple storage in commercial cold storage chambers, doesn't interfere in the efficiency of 1-MCP in apple maturation.
