In present study, the schizocarp morphology of 14 species belonging to Apiaceae family has been investigated. Light microscopy (LM) and scanning electron microscopy (SEM) have been utilized to highlight qualitative and quantitative features of studied species. Variations have been observed in macro- and micro-morphological features such as color, shape, symmetry, length, width, apex, epicuticular projections, surface patterns, anticlinal, and periclinal wall patterns. Schizocarp shapes observed were oval, round, triangular, linear, elliptic, and globose. Fruit was either homomorphic or heteromorphic. Crystalloids, stellate hair, multicellular spines, and platelets were mostly observed epicuticular projections. Surface patterns on the fruit surface were striate, rugulate-striate, reticulate, and striato-knotted. Both macro- and micro-morphological characters can serve as an important tool in classifying Apiaceae family at various taxonomic ranks. Substantial variations observed can assist as useful constraints at various taxonomic levels as they provide reliable and constant details. Disparities observed in schizocarp features can pave a path for Apiaceae family classification based on phylogenetic and molecular studies.
在本研究中，对伞形科的 14 种物种的分果形态进行了研究。利用光学显微镜（LM）和扫描电子显微镜（SEM）来突出研究物种的定性和定量特征。观察到宏观和微观形态特征的变化，如颜色、形状、对称性、长度、宽度、顶端、表皮突起、表面模式、垂周壁和周壁模式。观察到的分果形状为椭圆形、圆形、三角形、线性、椭圆形和球形。果实为同形或异形。晶状、星状毛、多细胞刺和小板主要观察到表皮突起。果实表面的表面模式为条纹状、条脊状-条纹状、网状和条纹状-结状。宏观和微观形态特征均可作为伞形科在不同分类等级上分类的重要工具。观察到的大量变化可以作为各种分类水平的有用约束，因为它们提供可靠和恒定的细节。分果特征的差异可以为基于系统发育和分子研究的伞形科分类铺平道路。
