Study on the Diversity of Morphological Characteristics of Leaves of Rabdosia rubescens (Hemls.) Hara
Abstract:Objective8 types of leaves of Rabdosia rubescens (Hemls.) were employed to find its germplasm resources diversity by observing the morphological parameters of leaf, the characteristics of leaf epidermis, and measurement its main characters. MethodsThe diversity of leaf type was described; the main characteristics such as leaf length, leaf width, the leaf apex length and width were measured; the characteristics of leaf epidermis were observed by means of light microscope after the leaves were exfoliated and temporary sectioned. ResultsThe form of epidermal cells, the patterns of anticlinal walls, the stomata index were anomocytic. But there existed significant difference in the form of leaf base , leaf length, leaf width and micro-morphology characteristics of the leaf epidermis(the cell number of the adaxial epidermis and abaxial epidermis, the stomal length,the stomal width,the stomal density).ConclusionIt exhibited mutation in morphological characteristics of the leaf and micro-morphology characteristics of the leaf epidermis in a long-term cultivation process.
