摘　　要：[目的]探讨生态入侵植物营养器官对环境的适应特性。[方法]采用高清显示植物组织晶体方法和石蜡切片法,对吉林省长春市郊区环境中的菊科豚草属三裂叶豚草(Ambrosia trifidaL.)的营养器官根、茎和叶横切面的组织结构进行了观察。[结果]生态入侵植物三裂叶豚草营养器官适合生态入侵的结构基础主要是通过加强根系的水分吸收和输导功能、提高茎叶的水分贮藏功能、降低茎叶水势促进植物对水分的吸收以及加强叶片的同化作用来实现在各种复杂环境条件下迅速生长发育,从而实现有效的生态入侵。[结论]为三裂叶豚草生态入侵的生物基础研究提供了参考。[Objective] The aim of this paper was to discuss the adaptability of ecological nutritional organs of invasive plants.[Method] By dint of high-definition display of plant tissue crystal method and paraffin section method,the vegetative organs root,stem and leaf cross-section of the organizational structure of Asteraceae Ambrosia trifida L.ragweed in the suburbs of Changchun City in Jilin Province were inspected.[Result] The structural basis for ecological invasive plant Ambrosia trifida L.vegetative organs was mainly through strengthening the roots of water absorption and transporting function,increasing the water storage function of leaf and stem,reducing the water absorption of stem and leaf for plants to promote water absorption and to enhance the assimilation of leaves to achieve a variety of complex environmental conditions in the rapid growth and development in order to achieve an ecological invasion.[Conclusion] The study provided reference for the biological fundamental research of Ambrosia trifida L..
