摘要
研究了不同浓度的Mn2+对小麦幼苗叶片光合特性的影响。实验结果表明,不同浓度的Mn2+处理都能够提高小麦幼苗的叶绿素含量,当Mn2+浓度为1.0mg/L、1.5mg/L时,叶绿素含量分别比对照增加了54.32%、71.92%。不同浓度的Mn2+都能够提高小麦叶绿素荧光动力学参数Fo,最大荧光产量Fm,ETR,NPQ及qNP,当Mn2+浓度为1.0mg/L分别比对照增加了2.78%,6.20%,32.09%,6.62%,0.93%。1.0-1.5mg/L的Mn2+对小麦幼苗生长具有促进作用。
The chlorophyll content and chlorophyll fluorescence were studied after treatment with different Mn^2＋ concentrations on wheat seedling. The results indicated that the treatment of the Mn^2＋ at different concentration can increase the content of chlorophyll. When the Mn^2＋ s concentration was 1.0mg/L, 1.5mg/L,the content of chlorophyll was increased by 54.32%, 71.92% indirectly. And the Manganese at 1.0mg/L concentration can increase Fo,Fm, ETR, NPQ, qNP by 2.78%, 6.20%, 32.09%, 6.62%, 0.93%. It was suggested that 1.0-1.5mg/L Mn^2＋ treatments were good for wheat seedling growth and development.
