The data in Table 1 show that the green life of Cavendish bananas sourced from three growing districts decreased with an increase in storage temperature and an increase in ethylene concentration. Significant effects of log10 ethylene concentration (P < 0.001), storage temperature (P < 0.001), their interaction (P < 0.001) and the square of log10 ethylene concentration (P = 0.019) were observed. The general equation for the fixed variables was calculated as: y = 5.714 (±0.456) − 21.081 (±1.861) * x − 0.824 (±0.349) * x2 − 0.097 (±0.022) * z + 0.547 (±0.066) * x * z where y = green life (days), x = log10 ethylene concentration (μL/L) and z = storage temperature (°C). Standard errors of the regression coefficients are in parentheses. An extra random term which allowed for the heterogeneity of variance associated with the ethylene concentrations was also included in the model.
