水分逆境包括干旱逆境和水涝逆境。国内外树木水分逆境的研究结果表明,干旱胁迫导致树木生长速率下降,光合速率、气孔导度和蒸腾强度随之降低,受影响的程度随胁迫强度的增加和持续时间的延长而加剧[1,2,3,5,7,8,10]。短期水涝对生长和生理特性影响不大,持续水涝则严重影响...
Water stress includes drought stress and waterlogging adversity. The results of tree water stress at home and abroad showed that the drought stress led to the decrease of tree growth rate and the decrease of photosynthetic rate, stomatal conductance and transpiration intensity, and the degree of influence was exacerbated with the increase of stress intensity and duration [1, 2,3,5,7,8,10]. Short-term waterlogging has little effect on growth and physiological characteristics, but continued waterlogging seriously impacts on ...
