Abstract: 

This study was conducted to investigate the effects of different temperatures on seed germination of Plantago ovata and also to evaluate cardinal temperatures. Various constant temperatures (5, 10, 15, 20, 25, 30 and 35oC) were conducted in a completely randomized design with four replications. The germinated seeds were counted every day and the rate of germination percentage, cumulative germination and cardinal temperatures of Plantago ovata seed germination based on two regression models including Intersected-lines Model and Quadratic Polynomial Model were calculated. The effects of temperatures on rate and percentage of germination was significant. The highest germination rates were in 20oC (R50=0.067). Based on the two regression models, Intersected-lines Model and Quadratic Polynomial Model, the cardinal temperatures (Tbase, Topt and Tmax) of Plantago ovata seeds were: (3.9-4.5), (18.8-21.1) and (33.7-34.1)oC, respectively. With increasing temperature, the more suitable conditions in terms of temperature, is created for Plantago ovata seed germination and germination rate is increased.
