8种园林彩叶植物叶片显色部位分析
Coloration tissue analysis of leaf color in eight garden colored-leaf plants
摘要
Abstract
[Objective]The purpose of this experiment was to study leaf structure and coloration tissue location of he-liophyte including Hibiscus rosa-sinensis var. variegata, Codiaeum variegatum var. pictum, Brassica oleracea var. acephala and Loropetalum chinense Olive var. rubrum Yieh.and shade plants including Syngonium podophyllum cv. ' White Butterfly' , Rhoeo discolor Hance, Stromanthe sanguinea Sond and Excoecaria cochinchinensis Lou. [ Method ] After fixed with FAA, the fresh leaves were made into temporary slices to observe under microscope and photographed. [ Result ]The coloration tissue of Excoecaria cochinchinensis Lour, Hibiscus rosa-sinensis var. variegata, Brassica oleracea var. acephala, Rhoeo discolor Hance and Stromanthe sanguinea Sond existed in leaf epidermis, and Codiaeum variegatum var. pictum, Loropetalum chinense Olive var. rubrum Yieh, and Syngonium podophyllum cv. 'White Butter-fly' existed in palisade tissue or spongy tissue of mesophyll. [Conclusion]In summary, heliophyte and shade plants had similar coloration tissue with pigment in leaf epidermis or mesophyll tissue. Ecological characteristics were not the sole indicator for color expression in the color-leafed plants.关键词
