In the first trial, 1-MCP at the highest rate of 100 nL L−1 reduced stem end gray mold by 9.7%, but the regression of decay on 1-MCP rate was not significant (Fig. 1). In the second trial,
100 nL L−1 of 1-MCP reduced stem end gray mold by 78.6%. In addition, the regression of decay on 1-MCP concentration was significant (P = 0.008) (Fig. 1).
