紫茎泽兰根际土壤对刺梨化感作用的潜在机制综述与研究展望

Review and Research Prospect of Potential Mechanism of Rosa roxburghii Chemosensitization in Rhizosphere Soil of Eupatorium adenophorum Spreng

摘要: 本研究旨在探究紫茎泽兰根际土壤对刺梨的化感作用及其机制。通过整合相关研究资料，从紫茎泽兰的生物特性与入侵现状、化感作用的基本理论及刺梨的生物学特性与经济价值入手，重点阐述了紫茎泽兰根际土壤对刺梨化感作用的可能机制，包括化感物质的释放与传输，对刺梨种子萌发、幼苗生长、生理生化指标(光合作用、呼吸作用、抗氧化酶系统)以及土壤微环境(土壤微生物群落、土壤养分循环)的影响。研究表明，紫茎泽兰根际土壤极有可能对刺梨存在化感作用，该研究为合理应对外来入侵植物对本地经济作物的影响提供了参考，对维护本地生态平衡和保障刺梨产业发展具有重要意义。

Abstract: This study investigates the phytochemical interactions between Eupatorium adenophorum Spreng and its invasive species, Rosa roxburghii, focusing on their mechanisms. By synthesizing existing research, this work examines the biological characteristics of Eupatorium adenophorum Spreng, including its invasive status, fundamental theories of phytosinergic interactions, and the economic value of Rosa roxburghii. The analysis highlights potential mechanisms including phytosinergic substance release and transmission, as well as their effects on Rosa roxburghii seed germination, seedling growth, physiological parameters (photosynthesis, respiration, antioxidant enzyme systems), and soil microenvironment (microbial communities, nutrient cycling). The findings demonstrate that Eupatorium adenophorum Spreng rhizosphere soil likely exerts phytosinergic effects on Rosa roxburghii. These insights provide valuable references for managing invasive alien plants affecting native cash crops, while also contributing to ecological conservation and supporting the sustainable development of Rosa roxburghii industries.
