水分对棕榈藤分布和生长的影响研究进展

棕榈藤是热带森林中兼具经济、生态价值的一类攀援植物，水分是棕榈藤分布和生长的重要限制因子，系统总结水分对棕榈藤分布和生长的影响对棕榈藤培育具有指导意义。文章综述了水分对棕榈藤分布和生长影响方面的研究进展，重点概述了棕榈藤幼苗阶段和萌蘖阶段应对水分变化的响应、水分和光照的交互作用对棕榈藤生长的影响，以及不同藤种对水分需求的差异等方面的研究成果，并从棕榈藤抗性生理和分子机制、影响棕榈藤生长的水分及其他生态因子耦合作用、棕榈藤高效育苗体系和不同区域棕榈藤地理分异规律等4个方面提出了今后的研究重点，以期为解决棕榈藤高效培育中存在的瓶颈问题提供参考。

Research Advances in the Effect of Water on Distribution and Growth of Rattan

Rattan is a kind of climbing plant with both economic and ecological value in tropical forests. Water is an important restriction factor to distribution and growth of rattan. It is therefore of guiding significance to systematically summarize the effect of water on distribution and growth of rattan. This paper reviews the research progress in the effect of water on distribution and growth of rattan, with the focus on the responses of seedling stage and budding stage to water changes, the effects of water and light interaction on the growth of rattan, and the differences in water demand of different rattan species. In order to provide reference for solving the bottleneck problems in efficient cultivation of rattan, the paper puts forward the future research direction from four aspects of strengthening the physiological and molecular mechanism of resistance, coupling effect of water and other ecological factors to the growth of rattan, efficient rattan seedling culture system, and geographical differentiation of rattan in different regions.
