摘要/Abstract

摘要： 应用蔡司荧光倒置显微镜观察17种(包含7栽培种)李属(广义)植物的果实表皮微形态特征。结果显示，果实表皮微形态多样，气孔复合体类型、气孔器形状、气孔大小、气孔密度及气孔周围纹饰等在李属(广义)植物不同类群中表现出各自独立的特点；一些性状如表皮细胞垂周壁式样、角质层纹饰和气孔复合体类型在属内各类群中出现分化规律，在各亚属之间表现出过渡性和连续性。研究表明，果实表皮微形态特征部分性状可作为李属(广义)植物识别的依据。果实表皮微形态特征在各类群之间变化，反映了不同类群对生态环境的适应。

关键词: 李属(广义), 微形态特征, 果实表皮

Abstract: In this paper, the micro-morphological features of fruit epidermis of 17 species (including 7 cultivars) in Prunus (sensu lato) were investigated using Zeiss Axio observer Z1 under bright field. The fruit epidermis exhibited diverse micro-morphologies. The type of stomatal complex, shape of stomata, size of stomata, density of stomata, and the ornamentation around the stomata show uniqueness in different taxa of Prunus. Some features such as the anticlinal cell wall pattern, cuticle ornamentation and the type of stomatal complex, appear to differentiate in different taxa within the genus, and show transition and continuity between the subgenera. Some micro-morphological features of fruit epidermis are helpful in identifying the species to which the fruits belong. The micro-morphological features of the fruit epidermis vary among different taxa of Prunus, reflecting the adaptation of different taxa to the ecological environment.

Key words: Prunus (sensu lato), micro-morphological features, fruit epidermis
