Abstract：
Using scanning electron microscopy (SEM), six Salsola species from Iran were examined for their epidermis, seed, and fruit micromorphology. Among them were S. brachiata from section Heterotricha, S dendroides, S. incanescens, and S. orientalis from section Caroxylon, S. kali from section Kali, and S. turcomanica from section Physurus. Epidermal cells are divided into three types. There were diamond, irregular, and polygonal cells, as well as straight and undulated walls. Studied species of Salsola have smooth or sculptured fruit surfaces, and there are three main types of fruit surface ornamentation. There is a significant difference between these species based on the type of hair and density of the fruit. Seed shape and color have little systematic significance. The seed epidermis is composed of polygonal, elongated polygonal, irregular, and diamond cells. Although polygonal and irregular testa cells are most common, their size and shape can provide additional information and useful diagnostic characteristics at both specific and infraspecific levels. For taxonomic separation, the current study provides novel insights at micromorphological levels. RESEARCH HIGHLIGHTS: This article reports halophyte are shown as models for adaptation to extreme habitats. These plants are placed among the ecological communities of xerophytes. Here, for the first time, the microstructural analysis of Salsola has been investigated. Additionally, it provides new insights into plant species\' response to extreme conditions, as well as possible adaptation strategies at the micromorphological level.
摘要：
使用扫描电子显微镜（SEM），对来自伊朗的六种Salsola物种的表皮进行了检查，种子,和果实微观形态。其中包括来自Heterotricha部分的腕虫，杜鹃花，S、incanescens，和来自Caroxylon部分的东方链球菌，卡利区的S.卡利，和来自Physurus科的Turcomanica。表皮细胞分为三种类型。有钻石，不规则,和多边形细胞，以及笔直和起伏的墙壁。研究过的Salsola物种具有光滑或雕刻的果实表面，水果表面装饰有三种主要类型。根据头发的类型和果实的密度，这些物种之间存在显着差异。种子形状和颜色没有什么系统意义。种子表皮由多边形组成，细长的多边形，不规则,钻石细胞虽然多边形和不规则的睾丸细胞是最常见的，它们的大小和形状可以在特异性和特异性水平上提供额外的信息和有用的诊断特征.对于分类分离，当前的研究提供了微形态学水平的新见解。研究重点：本文报道了盐生植物作为适应极端栖息地的模型。这些植物位于旱生植物的生态群落中。这里,第一次,已经研究了Salsola的微观结构分析。此外,它提供了对植物物种对极端条件的反应的新见解，以及微形态学水平上可能的适应策略。
