| Abstract:
To study the germination characteristics and cardinal temperatures of Nepeta binaludensis a laboratory experiment was conducted. In this experiment the effects of seven constant temperatures including 5, 10, 15, 20, 25, 30 and 35oC and three alternate temperatures including 5/10, 10/20 and 20/30oC on germination percentage and germination rate was studied. The highest germination percentage was obtained at temperaturesbetween20-30oC while the highest germination rate was recorded at 20 0C. Alternate temperatures have also a significant effect on germination characteristics of this species. The highest germination percentage and germination rate were recorded in alternate temperature of 20/30 0C. Base, optimum and critical temperatures were 7.4-9.9, 22.9-23.7 and 35.7-37.1oC, respectively.
