Abstract

The main objective of this study was to develop a seedling EMERGENCE model for FABA BEAN, including determination of cardinal TEMPERATUREs, biological day's requirement for EMERGENCE and FABA BEAN TEMPERATURE response curve. To do this, four FABA BEAN cultivars (Barakat, Saraziri, Eraghi, and Gavi) were sown at 11 sowing dates (every month) and the number of days from sowing to EMERGENCE were recorded. Beta, Segmented, Curvilinear, Quadratic and Dent-like models were applied to describe the relationship between EMERGENCE rate and TEMPERATURE. Root Mean Square Error (RMSE), coefficient of determination (R2), linear regression coefficients (a,b) and correlation coefficient (r) were used to detect the perfect model. Results indicated that response of FABA BEAN EMERGENCE to TEMPERATURE is best described by segmented function. Cardinal TEMPERATUREs Estimated by this model were 0.98oC to 1.61 oC for base TEMPERATURE, 24.9oC to 28.82oC for optimum TEMPERATURE and the value of 35 oC was assumed as ceiling TEMPERATURE. Estimation of biological days requirement by segmented model showed a significant difference between cultivars; cv. The EMERGENCE of Gavi small seeds occurced 6.65 day with the highest EMERGENCE rate (0.09 d-1). Biological day's requirement for other cultivars ranged between 8.60 and 9.72 days. The quantitative information provided by this study can be used in prediction of EMERGENCE under diverse TEMPERATURE conditions.
