Abstract
Seed germination usually is the most important determination of success or failure of plant establishment and if moisture is in optimum, the temperature threshold determines the rate and final germination percentage therefore prediction of the time and rate of germination in a suitable temperature range is decisive factor for plant establishment. This experiment evaluated regression models to estimate the cardinal temperatures of Salvia mirzayanii seeds and experiment carried out in completely randomized design with four replications in 2015 at the laboratory of Faculty of Agriculture, University of Guilan, Iran. Salvia mirzayanii seeds were placed in thermal treatments 5, 10, 15, 20, 25, 30, 35 and 40 ˚C. In order to describe the relationship between rate and temperature of germination were used segmented, curve-linear, quadratic, beta and dent-like models. According to the value of RMSE 0.26 Adj R2 0.89 and Akaike index -76.15 in segmented model, this model was more suitable for rate of Salvia mirzayanii seed germination than temperature. Based on this model, base, optimum and maximum temperature were 5.47, 22.14 and 40.84 ˚C respectively. In terms of practical, estimated cardinal temperature in the experiment can be considered in Salvia mirzayanii cultivation.
