The main goal of this study is to developa Faba bean plant sprouting model that includes a cardinal temperature determination and a required biologic day for Faba bean sprouting ( or to determine the Faba bean sprouting reaction to temperature). For this purpose, in a farm test, 4 cultivars of Faba bean plants (Barekat, Saraziri, Eraghi and Gavi) were cultivated on 11 sowing dates (one in each month ) and the required days to their sprouting were recorded. Beta, curve, quadratic and Sawtooth models were used to describe relationship between the sprouting rate and the temperature . To select the best model, it has been used an average root mean square deviation (RMSD), an R square (R2), simple linear regression coefficients (a and b) and a correlation coefficient (r). The results showed that the Faba bean sprouting reaction to temperature was better described by a Piecewise function. The estimation of the cardinal temperature by a Piecewise function indicated that the base temperature varies from 0.98C to 1.61C, and the optimum temperature varies from 24.99C to 28.8C for the different cultivars of Faba bean plants, but the ceiling temperature for all the cultivars was estimated at 35 degree centigrade. Also, the required biologic day estimation for sprouting as determined by the Piecewise model showed a significant difference between the cultivars, as the Gavi cultivars (which are smaller) germinated after 6.65 days (maximum rate is 0.09). For the other cultivars, the required biologic day fell between 8.60 and 9.31 days. The obtained data can be used to predict Faba bean sprouting in different temperature conditions.Downloads
