Effects of different treatments on the germination rate of Euphorbia humifusa

The influences of different temperatures, pH and humidities on the germination characteristics of Euphorbia humifusa were studied. The results showed that different temperatures, pH and humidities had significant influences on the germination characteristics of E. humifusa. The germination rate and index of E. humifusa seed performed best under 30 ℃ with 52% and 22.6, respectively; The best pH value was 7, under which the germination rate and germination index were 48% and 23.79, respectively. When the humidity was 90%, the E. humifusa seed germination rate and germination index were 55% and 23.02, respectively.
