Abstract

In this study, macro and micro morphology of the leaves of Abutilon figarianum and Abutilon pannosum(Malvaceae) were compared to assist as a relevant source of information and contribute towards the standards to dispose the quality and identity of these plants to avoid adulterations. Laminar size, shape, marginal type, leaf length, width, petiole length, leaf base angle and leaf apex angle were observed and measured. The relationships were illustrated by differences of radar shape. Transverse sections of the leaves were done using wax method. Three regions from each leaf were sectioned apex, middle and base. The epidermises formed of one layer of small polygonal cells covered by mucilage, large numbers of epidermal hairs appeared. The two leaves are dorsiventral. The vascular bundles arch shaped surrounded by collenchymas and ground parenchyma. Xylem consists of radial rows of cells. The phloem is found beneath. The structures at the apex, middle and bases of the leaves are similar, trichomes are denser in the middle region followed by the upper and lastly the lower region. Calcium oxalate druses are appeared in some parenchyma cells of the mid rib region, and these are of large numbers in the basal region.
苏丹药用植物的形态解剖学比较研究:第四部分。菲格兰和帕诺兰叶片
在本研究中,比较了布布隆(Abutilon figarianum)和布布隆(Abutilon pannosum) (malvacae)叶片的宏观和微观形态,以协助作为相关信息来源,并有助于处理这些植物的质量和识别标准,以避免掺假。对叶片的大小、形状、边缘类型、叶长、叶宽、叶柄长、叶基角和叶尖角进行了观察和测量。雷达形状的差异说明了这种关系。用蜡法制作叶片横切面。从每片叶子的顶端、中部和基部分三个区域。表皮由一层被粘液覆盖的小多角形细胞形成,表皮上出现大量毛。两片叶子背面朝上。维管束呈拱形,被厚壁组织和底薄壁组织包围。木质部由放射状的细胞行组成。韧皮部在下面。叶尖、叶中和叶底的结构相似,毛状体在叶的中部较密,其次是上部,最后是下部。在中肋区的一些薄壁细胞中可见草酸钙结节,在基底区有大量的草酸钙结节。
