现代月季(Rosa hybrida Hort.)种子实为瘦果。高效液相色谱分析表明,现代月季的果皮和种皮内脱落酸(ABA)的含量较高(分别为0.85和1.38μg/g),而其胚中的ABA含量很低(0.18μg/g)。因此,可以认为现代月季种子休眠的主要原因是果皮和种皮内含有较高水平的ABA。
Rosa hybrida Hort. Seed is actually achene. High performance liquid chromatography (HPLC) analysis showed that the content of abscisic acid (ABA) in the pericarp and seed coat of modern rose was higher (0.85 and 1.38 μg / g, respectively), while the ABA content in the embryo was very low (0.18 μg / g) . Therefore, it can be considered that the main reason for the dormancy of modern rose seeds is the higher level of ABA in the pericarp and seed coat.
