摘　　要：采用实验室双层纸上发芽法,通过温汤、苏打水和NAA浸种处理草豆蔻种子,并进行干燥和保湿贮藏实验,探究草豆蔻种子的萌发特性和贮藏特性。结果表明,草豆蔻种子不耐高温,30~60℃温汤浸种30 min,草豆蔻种子可以萌发,70℃以上难以发芽;用苏打水浸泡2 h、8 h,NAA_(5)及NAA_(50)浸种比清水处理发芽势高。在干燥和湿沙贮藏条件下种子生活力差异极显著,贮藏条件和贮藏时长的交互作用下,种子生活力差异极显著;草豆蔻种子不做处理常温放置在室内,30~60 d便会失活,但在低温潮湿环境下,种子生活力可以维持5个月以上;最优贮藏方式是保湿保鲜(2~3℃)贮藏,在第5个月使用TTC染色法仍有87%的草豆蔻种胚具有活力。Alpinia hainanensis K.Schumann seeds were treated with warm soup,soda water and NAA,and dried and moisturized for storage.The germination and storage characteristics of Alpinia hainanensis K.Schumann seeds were studied.The results showed that the seeds could germinate when soaked in warm soup at 30-60℃for 30 min,but could not germinate above 70℃.After soaking in soda water for 2 hours and 8 hours,the germination potential of seeds soaked in NAA_(5)and NAA_(50)was higher than that treated with water.Seed viability was significantly different under dry and wet sand storage conditions,and significantly different under storage conditions and storage time.Alpinia hainanensis K.Schumann seeds placed indoors at room temperature without treatment would be inactivated for 30-60 days,but in low temperature and humid environment,seed viability could be maintained for more than 5 months.The optimal storage method was moisturizing and fresh-keeping(2-3℃).87%of Alpinia hainanensis K.Schumann seed embryos were still active by TTC staining at the 5th month.
