摘要:
针对目前人们对小檗属植物刺的来源存在不同见解，本研究通过实体解剖及石蜡切片技术，以紫叶小檗为代表研究小檗属植物刺的形态和发生，结果表明，紫叶小檗的刺均为叶刺，而非茎刺，明确了小檗属的刺为叶的变态。
Abstract:
In view of the different opinions on the origin of the spines of Berberis, we studied the morphology and occurrence of the spines of Berberis by means of entity anatomy and paraffin section. The spines of Berberis descended from leaves, origins from leaf primordial, are leaf spines, not stem spines. It was clear that the spines of Berberis belong to one of the leaf metamorphosis types.
