The effect of different temperatures treatment on fire hemp seeds germination

The effects of temperature on the germination of fire hemp were investigated. Fire hemp seeds germinated from the minimum temperature 5℃to the maximum temperature 35℃. The maximum germination percentage was 95% at 20℃, But the optimum germination occurred at 25℃, with the germination energy and germination index reaches its maximum, 92.3% and 40.3%, respectively. The germination rate declined significantly as temperature increases or decreases from the optimum temperature 25℃. using variance analysis, seed germination rate differences were not significant, germination index were significant between 20℃and 25℃.
