Abstract: Temperature requirement in different stages of rose growth was crucial for precisely predicting the harvest time of cut rose. The daily average temperature of the budding day of cut rose and the accumulated temperature from budding to cutting flower were investigated as two major aspects of the temperature requirement. The results showed that the accumulated temperature from budding to cutting flower was 780 for low accumulated temperature rose and 980 for high accumulated temperature rose in Haining. Two models for predicting the harvest time of cut rose in Haining were built up based on the analysis of temporal characteristics of reaching the required accumulated temperature each year to guide the rose production.
