Abstract
The objective of this study was to develop a thermal model that can be used for prediction of saffron flowering time.
For this purpose, existing data on saffron flower emergence time were collected in a wide range of temperature regimes over the saffron production regions of Khorasan province (Iran). Linear second-order polynomial and 5-parameter beta models were used and statistically compared for their ability in predicting saffron flowering time as a function of temperature.
The results showed a significant delay in flowering date across the temperature gradient.
While beta model had a better statistical performance but the simple linear model also showed a good predicting ability and therefore, can be used as a reliable model.
