Abstract

采用室内与野外实验相结合的方法,对五蕊寄生(Dendrophthoe pentandra)种子萌发特性以及鸟类消化过程对其种子萌发的影响进行研究。结果表明:五蕊寄生种子对温度和光照较敏感,与黑暗条件相比,光照能显著提高种子的萌发率;20℃为种子萌发的最适温度,萌发率达53.8%,高温35℃及低温10℃均不利于种子萌发。研究发现纯色啄花鸟(Dicaeum concolor)是该植物的主要食果者,种子外的果肉不是限制种子萌发的关键因素,人为去除果肉并不能提高种子的萌发率,但可缩短种子萌发的时间,果实通过纯色啄花鸟类肠道消化后,随着粪便排出的种子萌发率显著提高(达69%),暗示纯色啄花鸟在五蕊寄生的种子萌发过程中具有重要的作用。
