荒漠河岸林植物木质部导水与栓塞特征及其对干旱胁迫的响应/Xylem hydraulic conductivity and embolism properties of desert riparian forest plants and its response to drought stress[J]

, 2012
以同处于干旱区的塔里木河下游(铁干里克)和黑河下游(乌兰图格)断面为研究区,比较了荒漠河岸林主要建群种胡杨(Populus euphratica)、柽柳(Tamarix spp.)、疏叶骆驼刺(Alhagi sparsifolia)和花花柴(Karelinia caspia)在长期遭受不同干旱胁迫下的根、枝条木质部导水力和栓塞化程度的变化特征,并分析了木质部导水对干旱胁迫的响应及适应策略.结果表明:1)黑河下游荒漠河岸林植物的导水能力显著高于塔里木河下游,其中柽柳、胡杨 ...

The strategies of biomass allocation of two desert annul plants and their morphological and physiological adaptive teristics under water stress

, 2010
水分胁迫是影响干旱和荒漠地区生态系统结构和功能变化的主要驱动力。生活在干旱和荒漠等极端缺水环境中的植物，在长期进化过程中，作为主动适应策略，在生物量分配、形态和生理特征上均表现出一定的可塑性。由于受水分条件的限制，干旱和荒漠地区乔灌木分布稀疏而单调，但却广泛分布着短命或一年生草本植物。因此，分析水分胁迫下，荒漠地区草本植物在不同生活史阶段的生物量分配过程，对研究植物各部分之间碳存储比例以及估算植物地下碳存储量，具有重要的理论意义。分析植物在水分胁迫下形态和生理的适应特征 ...
