摘　　要：构树具有较强的环境适应能力,能在多种逆境中维持正常的生长发育,是一种多功能综合性树种。构树对逆境的广适性是构树广泛分布的基础,也是作为生态环境修复树种的有力保障。综述了构树对非生物胁迫(干旱、盐碱、重金属、养分缺乏等)和生物胁迫(病虫害)抗性的研究进展,探讨了构树对不同逆境胁迫的生理生化响应机制,为构树资源的深入开发利用提供理论参考。Broussonetia papyrifera as a kind of multi-functional and comprehensive tree species,has a strong environmental adaptability and keeps the normal production and development in harsh habitats.The adaptability of Broussonetia papyrifera to adversity is the basis of its wide distribution,and also is a strong guarantee as a tree species for ecological environment restoration.The research status of resistance of Broussonetia papyrifera to both abiotic stresses(drought,salinity,heavy metal and nutrient deficiency etc.)and biotic stress(diseases and pests)were mainly reviewed,and the mechanisms of physiological and biochemical responses to different stresses were discussed,aiming to provide theoretical reference for the further development and utilization of Broussonetia papyrifera resources.
