英文摘要	Investigations on seeds of Kickxia acerbiana were undertaken to elucidate their germination characteristics. Germination was assessed in fluctuating temperatures, both in continuous darkness and in alternating light/dark (12-hour photoperiod), and in response to gibberellic acid pretreatment. Germination was favoured in light/dark and fluctuating temperature regimes. Germination across all incubation temperatures in complete dark regimes was consistently low. Pretreatment with 2 mM gibberellic acid strongly promoted germination in the 12-/12-hour light/dark, 25/15 and 30/20 degrees C regimes. In the light and without pretreatment with gibberellic acid, the optimum germination temperatures were 25/15 and 30/20 degrees C, while at the highest temperature, 35/25 degrees C, no more than approximately 20% of seeds germinated. The germination velocity of K. acerbiana seeds decreased with increase in GA concentration at 30/20 degrees C temperature regime.
