绿化观赏竹的抗性研究进展

笔者对国内外绿化观赏竹抗性的研究进展做了较全面的总结,并参考其它植物抗寒性的研究思路与方法,对绿化观赏竹抗性的进一步研究提出了一些设想。目前国内绿化观赏竹抗寒性的研究领域主要有绿化观赏竹抗寒性良种选育与引种、抗寒耐旱生理及增强越冬抗寒性提高水分利用率的措施等方面,而对绿化观赏竹的抗寒锻炼、抗寒与旱害的动态发展过程及分子水平的研究等则还有待进一步加强,可能会成为未来绿化观赏竹抗性研究的发展方向。

Research Advance on Resistance of Landscape Ornamental Bamboo

The progress in the research on the cold endurance of bamboo was summarized comprehensively at home and abroad.In addition,based on the progress and techniques of researches on cold endurace of the plants,the authors also proposed some ideas on the future research of bamboo cold endurance.The recent researches on bamboo cold endurance are mainly about the following subjects：selection and introduction of foreign cold endurance breeds,physiological assessment of cold endurance and the measures to improve the winter-tolerance of bamboo.However,there have been little improvement on the studies of inner mechanisms of the cold endurance of bamboo,on the dynamic process of cold endurace and cold-injury,or on the molecular genetics,which are all important aspects in the progress of cold endurance study.So it is proposed that these subjects may become the future evolution directions of bamboo cold endurance research.
