干旱区园林植物抗旱机制研究进展

Advances of Drought Tolerant Mechanism Garden Plants in Arid Areas

干旱区水资源短缺是影响植物生长发育及分布的主要因素,也限制了园林植物在景观中的应用。文章从干旱胁迫下植物根系、叶片等形态结构及植物光合作用、渗透调节等生理生化2个方面综述了干旱区园林植物对干旱胁迫的响应机理,并提出未来抗旱机理的研究方向。

Water deficit has seriously affected the growth and distribution of plants in arid areas. What＇s more,the application of garden plants in landscape was also limited. An overview of garden plants of drought stress mechanisms was reported from two aspects which contain morphology including roots and leaves; physiology and biochemistry comprising membranes,photosynthesis,and osmotic adjustment and so on. New research directions of drought-resistance were also proposed in the future.
