摘要

Vitaceae, a globally important plant family, exhibits high diversity in reproductive and vegetative traits, but detailed investigations on seed micromorphology, seed coat anatomy, and leaf epidermal traits in Pakistan are lacking. This study investigates these traits across 14 representative species to evaluate their taxonomic, ecological, and evolutionary significance. Seed morphology and seed coat anatomy were examined using scanning electron microscopy (SEM), while leaf micromorphology and trichome diversity were analyzed with light microscopy (LM). Quantitative and qualitative traits, including epidermal cell shape, stomatal morphology, trichome type and density, seed shape, endosperm configuration, chalaza features, ventral infolds, and beak characteristics, were recorded. Ancestral state reconstruction and phylogenetic signal analyses were performed to evaluate interspecific variation and evolutionary patterns. Substantial interspecific variation was observed in both reproductive and vegetative traits. Seed traits, including seed shape, chalaza morphology, ventral infolds, and beak structure, revealed patterns of phylogenetic conservatism and divergence. Leaf traits, such as epidermal cell shape, stomatal features, and trichome density and type, reflected adaptive strategies to microclimatic conditions. Dense trichomes in Cissus trifoliata and Ampelocissus latifolia likely function in herbivory defense and microclimate regulation, whereas sparse trichomes in Vitis and Parthenocissus suggest alternative adaptations. Seed and leaf micromorphological traits are highly informative for taxonomic identification, phylogenetic inference, and ecological interpretation within Vitaceae. The integrated study provides a comprehensive dataset for 14 species, establishing a foundation for comparative and evolutionary research in Pakistan and contributing to broader knowledge of Vitaceae diversity in South Asia.
