الصفات الظاهرية والدقيقة لـ Citrus reticulata Blanco المزروع في شرق ليبيا

Abstract

Citrus reticulate Blanco is economically and medically important and cultivated in Al-Marj city (Libya). In this study, the morphological, epidermal and anatomical characteristics of Citrus reticulate were considered in a laboratory experiment through staining of cut sections and microscope visualization with the aim of providing detailed description of characteristics of this plant species. Morphological characteristics of leaves, fruits, and seed are very important in comparing between Citrus species. Epidermal attributes such as a variety of cell shapes, hypostomatic, anamocytic stomata, and the presence of secretory cavities on the upper surface of the epidermis are valuable characteristics in distinguishing Citrus species. Also, the mesophyll structure, the shape of vascular bundle, the presence of druses and the secretory cavities features have taxonomic value in the Citrus genus. Additionally, the petiole features, the presence of trichomes and druses and characteristics of the vascular bundles are important for determining phylogenetic relationships between Citrus species. Key words: Citrus reticulata, morphology, anatomy, secertory cavities and druses, Al- Marj (Libya).
