摘要：水分亏缺是一制约树木生长的重要环境因子，尤其是在干旱与半干旱地区。水分胁迫的影响表现在树木生长发育的许多方面，阐明在这些表现背后的生理生化、遗传、耐旱机制无疑有助于耐旱性品种选育。本文从ＤＮＡ转录及表达、光系统Ⅰ、Ⅱ（ＰＳⅠ、ＰＳⅡ）、气孔运动、树木生长适应与响应、水分利用效率、抗旱机制、耐旱性指标筛选及转基因耐旱植物等方面，对近几年来国内外一些试验结果进行了评述和探讨，并对耐旱性指标筛选、耐旱性工程植物等提出了自己的观点。
Water deficit is one of the most important environmental factors which limit plant growth, especially in arid and semiarid areas. Influences of water stress may be involved in many aspects on plant growth and development. Therefore, knowledge of these mechanisms in physiology, biochemistry, genetics and drought tolerance may assist in decision making in the future for drought resistance breeding. In this paper, we commented on and discussed some results obtained recently from extensive studies in the field in tree species, including influences on DNA transcription and expression, on PSⅠ and PSⅡ system, on stomata movement, on adaptation and response, on water use efficiency, mechanism of drought resistance, screening of drought tolerance index, and tolerance engineering. We presented our points in these aspects, especially in tolerance engineering. We presented our points in these aspects, especially in tolerance engineering and screening of effective traits by which selection is undertaken.
