Abstract

This study was carried out to determine the requirements of cardinal TEMPERATUREs and biological hours for GERMINATION of LENTIL by using different linear and nonlinear regression models. To do this, a split plot experiment based on randomized completely design with four replications was conducted in germinator. Experimental treatments were three LENTIL cultivars (Gacgsaran, Kimia and Bilehsovar) under seven fixed TEMPERATURE regimes (5, 10, 15, 20, 25, 30 and 35oC). Beta, Dent-like and Segmented models were applied to evaluate the relationship between GERMINATION rate and TEMPERATURE. Root mean square deviation (RMSD), coefficient of determination (R2), coefficients of variation (CV) and linear regression coefficients (a, b) were used to detect the perfect model. Results of fitting the models indicated that the response of LENTIL GERMINATION to TEMPERATURE is best described by a segmented function. Cardinal TEMPERATUREs estimated by this model were 0.89 to 1.23oC for base TEMPERATURE, 23.41 to 26.94oC for optimum TEMPERATURE and 35.15 to 45oC for ceiling TEMPERATURE. Significant difference in base TEMPERATURE among cultivars was not observed, but cultivars had significant difference in optimum and ceiling TEMPERATUREs. Biological hour's requirement for GERMINATION ranged between 25.43 to 31.37 hours. The quantitative information provided by this research can be used in prediction of GERMINATION of LENTIL cultivars.
