Abstract

The effect of alternating temperature on the germination of Pulsatilla tongkangensis seeds was investigated. Open pollinated seeds were wrapped in a moist paper towel for alternating temperature treatments. Seeds were sown in cells filled with Miracle-Gro Potting Mix and then topped with 0.5 cm of Miracle-Gro Seed Starting Potting Mix. The number of germinated seeds was counted daily until no further germination was observed for    3    to    4    days. The maximum germination rate (49%) was achieved in 18 days when seeds were treated at 22°C for    7    days followed by    5    °C for    7    days, and germinated at 20°C. The low germination rate could result from the inclusion of empty seeds. Mature P. tongkangensis seeds may not have a  shallow physiological dormancy since germination was not improved with 14 days of 5°C.
