| 摘 要： | 刺槐和油松由于其具有适应性强、成活率高等优点被作为我国北方地区的主要先锋造林树种，其栽培分布范围广泛。随着全球变暖和水资源短缺日益加剧，干旱已成为刺槐和油松生长中面临的主要非生物胁迫，引发了人工林林分退化、自然更新差、“小老树”和树梢干枯等问题。了解干旱胁迫对刺槐和油松生长的影响及响应机制对改进抗旱栽培技术、提高林分生产量、促进育种和发挥森林生态系统功能有重要的意义。从生长形态特征、生理生化变化方面概述刺槐和油松对干旱胁迫的响应机制，从选育新品种、抗旱栽培技术及基因工程方面总结提高两者抗旱性的途径，并对未来刺槐和油松耐干旱研究的方向进行展望，为刺槐和油松的耐旱研究及种植和抚育管理提供理论参考。

| Abstract: | Robinia pseudoacacia and Pinus tabuliformis are regarded as the main pioneer tree species in north China because of their strong adaptabilities and high survival rates.With the increase of global warming and water shortage,drought has become the main abiotic stress in the growth of the two species,leading to the degradation of artificial forest stand,poor natural regeneration,"small old trees",tree top drying and other problems.Understanding the effects and response mechanisms of drought stress on the growth of the two species is of great significance for improving drought-resistant cultivation techniques,increasing stand yield,promoting breeding and exerting forest ecosystem functions.This study summarized the response mechanism of R.pseudoacacia and P.tabuliformis to drought stress in terms of growth morphological characteristics,physiological and biochemical changes.The ways to improve drought resistance were summarized from the aspects of breeding new varieties,drought resistance cultivation techniques,and genetic engineering.The research direction of drought tolerance of R.pseudoacacia and P.tabuliformis in the future was prospected in order to provide theoretical reference for drought tolerance research,planting and rearing management of the two species. |
