摘　　要：金叶榆(Ulmus pumila‘Jinye’)是我国具有自主知识产权的彩叶植物树种,不仅观赏价值高,且生长迅速、耐强度修剪、抗逆性强,为我国寒冷、干旱及盐碱地区提供了一个乔灌皆宜的优良彩叶植物新品种。分别从金叶榆的抗寒性、抗旱性、抗涝性、抗盐碱性以及光胁迫对其叶色的影响等方面进行总结,概述了金叶榆抗逆性研究的意义、近年来的研究进展,并总结了当前研究的侧重点。最后指出,金叶榆是研究金色叶形成机理的良好材料,目前其抗逆性在分子和基因层面的研究还有待发掘,开展研究可为金叶榆的推广应用提供理论依据。Ulmus pumila'Jinye'is famous for its golden bright leaves,its ornamental period last from spring to the autumn.U.pumila'Jinye'not only has a high ornamental value,but also has a strong resistance.Based on the cold resistance,drought resistance,waterlogging resistance,salinity tolerance and the effects of light stress on its leaf color,this paper summarizes the significance of the research on the resistance,the research progress in recent years of the plant and summed up the focus of the current research.Finally,it is pointed out that it is a goodmaterial for studying the formation mechanism of golden leaves,and the research on the molecular and genetic aspects of the study of resistance to stress is still to be explored,which can provide a theoretical basis for the popularization and application of U.pumila'Jinye'.
