中文摘要	采用便捷式光合仪LI-6400XT的荧光叶室6400-40测定了3种自然生长的植物的叶绿素荧光参数日变化,以研究金昌干旱区植物的抗光抑制能力,揭示其对强光环境的适应性。结果表明:骆驼蓬的叶绿素荧光参数值都大于猪毛菜和盐生草。骆驼蓬和盐生草Fo呈先升后降再升趋势,猪毛菜的Fo呈先降后升再降趋势; 3种植物Fv /Fo、Fv /Fm、Fv'/Fm'呈先降后升的趋势;骆驼蓬的Yield表现出先降后升再降趋势,猪毛菜和盐生草的Yield呈双峰型; 3种植物的qP呈双峰型; ETR、NPQ呈先升后降的趋势。猪毛菜ETR、NPQ和qP、骆驼蓬ETR和qP、盐生草Fo、NPQ和ETR与光照强度在0. 05水平上呈显著正相关;猪毛菜NPQ和qP、骆驼蓬ETR、qP、Fv /Fm、Fv'/Fm'、Fv /Fo、盐生草Fv /Fm、Fv'/Fm'与气温有显著相关性。3种植物的光抑制强弱为:骆驼蓬>猪毛菜>盐生草,骆驼蓬的抗光抑制能力最强,更适应强光环境。强光下骆驼蓬较大程度的通过热耗散过剩光能保护光合器官免遭破坏,而猪毛菜和盐生草可能还有其它因素的调节。
英文摘要	The diurnal changes of chlorophyll fluorescence parameters of Peganum harmala L,Salsola collina Pall and Halogeton glomeratus that grow naturally were studied by using the fluorescent leaf chamber 6400-40 of the convenient photosynthetic apparatus LI-6400XT to study the anti-light suppression ability and the adaptability to strong light of the plants in the Jinchang area. The results showed that the chlorophyll fluorescence parameters of Peganum harmala were all higher than that of Salsola collina and Halogeton glomeratus. The Fo of Peganum harmala and Halogeton glomeratus showed a tendency to rise firstly and then fall down,and then rise again; and the Fo of Salsola collina was decreased firstly and then rise,and then decreased. The trends of Fm, Fv,Fv /Fo,Fv /Fm,Fv'/Fm' showed decrease firstly then riseing. The yield of Peganum harmala showed trend of decrease-increase-decrease,and the yield of Salsol acollina and Halogeton glomeratus were double-peaked. The qP of three plants were double peak. ETR and NPQ showed first rise and then fall trend. The light suppression ability of three plants is: Peganum harmala > Salsola collina > Halogeton glomeratus. Peganum harmala has stronger ability to resist light than Chenopodiaceae,and more suitable for strong light environment.
