Seed dormancy classes determine both population and species-level processes which can be crucial in the life cycle of many plants. However, there are no studies of a dormancy cline between levels of morphophysiological dormancy (MPD). We aimed to determine the class of seed dormancy of Narcissus yepesii exhibits in order to explore links between different dormancy levels, previously characterized in two closely-related phylogenetic congeners, N. alcaracensis and N. longispathus.

水仙（Amaryllidaceae）的种子发芽：形态生理休眠水平的梯度变化

种子休眠类别决定种群和物种水平的过程，这对许多植物的生命周期至关重要。但是，没有关于形态生理学休眠（MPD）水平之间的休眠谱系的研究。我们旨在确定水仙种子展品的休眠类型，以探索不同休眠水平之间的联系，这些休眠水平以前以两个密切相关的系统发育同源物N. alcaracensis和N. longispathus为特征。
