| 摘 要： | 杜鹃花作为我国传统的"十大名花"之一,在我国有着丰富的野生杜鹃资源。但大部分野生杜鹃品种分布在高海拔地区,在引种栽培过程中,由于高温、干旱及土壤盐渍等各种胁迫,严重影响了杜鹃花正常的生长发育以及推广应用。因此综述杜鹃属植物的耐热、耐寒、抗旱等各种抗性及逆境交叉适应性机理的研究进展,能够为杜鹃属植物抗性研究提供相关理论参考,为引种栽培提供相应实践指导。

| Abstract: | Rhododendron flowers are regarded as one of Chinese traditional top ten famous flowers and have rich wild resources in China. However, most of wild varieties are distributed in high altitude areas. Different stresses such as high temperature, drought, soil salinity and so on during cultivation, have se- verely affected Rhododendron＇ s normal growth and development and popularization and application. Therefore, research progresses on a variety of resistance such as heat resistance, cold hardiness, and drought, and cross-adaption of Rhododendron L. , were summarized to provide relavant theoretical refer- ences for resistance research and corresponding pratical instructions for cultivation. |

| Keywords: | Rhododendron heat resistance cold hardiness drought tolerance salt tolerance cross-adaptation |
