Evaluation of Germination and determination of cardinal temperatures of Cannabis sativa by using regression models
To determine the specific temperature of Medicinal Cannabis sativa, the effects of different temperatures on germination, in a laboratory study in a completely randomized design with three replications were studied. Germination response assessment at constant temperatures (3, 5, 10, 15, 20, 25, 30,...

| description | To determine the specific temperature of Medicinal Cannabis sativa, the effects of different temperatures on germination, in a laboratory study in a completely randomized design with three replications were studied. Germination response assessment at constant temperatures (3, 5, 10, 15, 20, 25, 30, 35, 40 and 45ºC) was conducted. The germinated seeds were counted every day and the rate of germination percentage, cumulative germination and cardinal temperatures diagram of Cannabis sativa seed germination based on 3 regression model including segmented model, Beta model and Dent like model. The results showed that the temperature increase of 3 to 25°C significantly increases the germination rate, while the germination rate did not differ at 25 to 40°C. Also with increasing temperature over 25°C, germination was reduced. Dent like model such as higher accuracy in determining the cardinal temperatures hemp seed germination was compared with other models, Base, optimum and maximum temperature of seed germination of Cannabis sativa based on Dent like model was determined 1, 26-39.3 and 48°C respectively. |
