Abstract:

To solve the problem of the technology of Papaver nudicaule in introduction and cultivation. we had studied the effects of temperature on the germination of coat-pelleted Papaver nudicaule seed–bud. Using the temperature controller and consulting the examination methods of germination test. Between 3-5℃, the darkness was benefit to bud germination, between 15-20℃, the germination wasn’t affected by light, below 5℃, the germination rate decreased obviously under light. The changes trend of germination index was similar to germination rate. Between 3-5℃, the germination energy under dark condition was significantly higher than light condition. The tread of germination energy had little difference between light and without light, all presented “S” profile. Temperature was a main limiting factor affecting the seed germination of coat-pelleted Papaver nudicaule seed–bud and light changed with temperature.
