Shuitu Baochi Xuebao, 2002 以栾树、黄连木、黄栌为试验材料,刺槐作为对照,系统测定各树种的叶片水势、气孔导度、蒸腾速率、光合有效辐射、空气相对湿度、土壤温度、土壤水分含量、土壤呼吸速率等水分生理生态指标。结果表明:叶片水势日变化幅度由大到小依次为栾树>刺槐>黄栌>黄连木;蒸腾速率由大到小为刺槐>黄栌>栾树>黄连木;土壤呼吸速率由大到小为黄连木>栾树>刺槐>黄栌。各树种水分利用效率黄连木最高,其次为栾树和刺槐,黄栌最低。

Effects of Cadmium and Its Subcellular Distribution on the Photosynthesis of Cauliflower [PDF]
, 2008 研究Cd在花椰菜的残留分布及其对光合作用的影响,设置0、5、15、30mg·L-14个Cd浓度的水培试验,测定生长期间叶片的叶绿素含量,光合作用参数,Cd的亚细胞分布,化学形态分布和器官(根、茎、叶、花球)分布。结果表明,Cd处理两周后,叶片叶绿素a和b含量明显比对照降低,气孔导度、净光合速率和蒸腾速率亦显著降低,胞间CO2浓度变化不大。不同浓度Cd处理的叶片中Cd在亚细胞中的分布主要以细胞质组分为主(70.19%~74.40%),其次为细胞壁组分(22.56%~27.12%),叶绿体和线粒体组分仅占0.
