摘要

(茄科)包括栽培和野生植物，在世界上有1400种，在伊朗有14种。由于形态相似性、表型可塑性和杂交性，茄属是一个分类复杂的属。对这一重要属的解剖特征进行了有限的研究。本研究对伊朗茄属2个亚属的10种本地和外来种进行了解剖学研究。光镜下对叶片叶肉、中脉和毛被进行了分析。采用手工制作横截面法，以甲苯胺蓝为着色剂。主要维管束的长度和宽度、厚壁厚度、毛状体密度、薄壁链的厚度、薄壁层的厚度和中脉的长度和形状是所研究种的诊断特征。在UPGMA树和PCA排序中，两个亚属的种被分离。本研究结果证实了所研究的茄属植物解剖特征在分类学上的重要性。

Leaf Anatomical Study of Solanum Species (Solanaceae) in Iran

(Solanaceae) comprises cultivated and wild plants with 1400 species in the world and 14 species in Iran. Solanum is a taxonomically complex genus due to morphological similarities, phenotypic plasticity and hybridisation. Limited studies were done on anatomical features of this important genus. In this project, 10 native and exotic species of Solanum in Iran belonging to two subgenera were examined anatomically. Leaf mesophyll and midrib and indumentum were analysed using light microscope. Hand-made cross section method and Toluidine blue as colouring agent were used. Characters as length and width of main vascular bundle, thickness of collenchyma, trichome density, thickness of parenchyma strand, thickness of lamina and length and shape of midrib were diagnostic features among species studied. In UPGMA tree and PCA ordination, species of two subgenera were separated from each other. Results of this study confirmed the taxonomic importance of anatomical characters in Solanum species studied.
