| The germination responses of Cassia mimosoides var. nomame seeds to temperature were examined under various conditions. The temperature range allowing germination was $20~40^{circ}C$, and the linear relationship between the germination rate and temperature appeared to exist between $28~38^{circ}C$ The total thermal time required for germination (10~80%) of C. mimosoides seeds ranged from 259 Kh (degree Kelvin$ imes$hours) to 421 Kh and base temperature range was relatively constant, i.e., $23.39~26.68^{circ}C$. In the increasing temperature (IT) regime, C. mimosoides seeds started to germinate at $16^{circ}C$ and showed greater germination rate with increasing temperatures. The final germination rate was 64% at $36^{circ}C$. On the other hand, in the decreasing temperature (DT) regime, the seeds began to germinate at $36^{circ}C$, and the final germination rate was 52% at $20^{circ}C$. An induced dormancy occurred at $16^{circ}C$ in the DT regime. |
