| 摘 要： | 目的]探讨壶瓶碎米荠（Cardamine hupingshanensis）种子的萌发特性,为其引种和栽培提供指导。方法]调查壶瓶山国家自然保护区内壶瓶碎米荠的生态环境,并在不同的光照、温度、pH值和储藏条件下,对种子的发芽率进行测定。结果]在壶瓶山一带的自然分布区内,壶瓶碎米荠种子无休眠现象,种子能自然萌发成苗,其萌发特性完全适应了自然分布区内稳定的低温溪流环境。温度在15～25℃时,壶瓶碎米荠种子发芽率较高;超过25℃,种子发芽率和萌发速度迅速降低。壶瓶碎米荠种子萌发对pH值条件要求不严格。光照对种子萌发也有影响,但不是决定条件。自然通风条件下,壶瓶碎米荠种子寿命约为80 d。结论]人工育苗时,应该考虑温度和光照因素,萌发过程温度不宜超过25℃,种子保存需低温干燥。
