Electrostatic Conformational Electronic Structures Distortional Isomers Mixed-Valence Binuclear Cu Complex
2016/5/23
The electronic structure of the binuclear copper complex [Cu(2)(L)](3+) [L = N(CH(2)CH(2)N(H)CH(2)CH(2)N(H)CH(2)CH(2))(3)N] has been investigated by resonance Raman and electroabsorption spectroscopy....
为验证氮在植物解除重金属毒害中的积极作用和生理机制,本试验对巨桉(Eucalyptus grandis)幼苗在3种重金属(Cd、Cu和Pb)处理下增施氮肥的生长和光合生理效应进行研究。结果表明:Cd2+、Cu2+和Pb2+处理下,巨桉植株的叶绿素含量、光合作用、PSⅡ原初光化学反应量子产率等均显著低于对照植株;而在重金属处理的同时增施氮肥,则能显著促进植株生长,提高叶绿素含量,增强光合作用和PSⅡ...
以骆驼蓬幼苗为材料，采用盆栽试验研究不同浓度（0、50、100、200、400 mg·kg-1）Ni、Cu处理对骆驼蓬叶片光合作用、叶绿素荧光特性及生长状况的影响.结果表明： 随着Ni浓度的增加，骆驼蓬幼苗叶片的光合色素含量、净光合速率（Pn）、气孔导度（Gs）、蒸腾速率（Tr）、PSⅡ最大光化学效率（Fv/Fm）、PSⅡ电子传递量子产率（ΦPSⅡ）、光化学猝灭系数（qP）及各项生长指标均呈显著下...
