摘要: 以玉米种子丹科2162为材料,分别用含有稀土元素La、Ce、Gd的氯化镧(LaCl3.nH2O),氯化亚铈(CeCl3.7H2O),碳酸钆(Gd2(CO3)3.XH2O)同浓度的不同盐溶液浸种处理的方法,研究了不同稀土元素La、Ce、Gd在0.03%浓度下对玉米幼苗生理指标的影响。结果表明:在0.03%浓度条件下,稀土元素La,Ce,Gd可以提高玉米幼苗的叶绿素含量,促进幼苗个体生长(培养壮苗),改善光合生理特征,降低离体叶片失水速率等。

关键词: 玉米幼苗, 稀土元素, 个体生长, 光合生理特征, 离体叶片失水速率

Abstract: "Effect of the Rare Earths La,Ce,Gd on Dan Ke 2162 Maize Seedling Physiological Indexs under 0.03% concentration of the Rare Earths La,Ce,Gd are studied in the experiment.The results showed :the Rare Earths La,Ce,Gd increased chlorophyll of Maize Seedling,promoted Vegetative growth,improved Photosynthetic-physiological Characteristics,decreased Excised-leaf water loss rate,et al.under the 0.03%. "

Key words: Maize seedling, The rare earths, Vegetative growth, Photosynthetic-physiological character istics, Excised- leaf waterloss rate
