| 摘 要： | 以玉米幼苗刚好完全展开的1～5叶位叶片为材料,通过检测叶绿素含量和荧光参数特性,研究玉米不同叶位叶片的光化学活性.结果表明:随着叶位的上升,叶绿素含量逐渐增加;与第1,2位叶比,第4,5位叶具有更高的Fv/ Fm和ETo/RC,即第4,5位叶具有更强的光化学活性.

| Abstract: | In order to study the photochemical activity of maize leaves at position 1-5,the chlorophyll content and fluorescence characteristic parameters of 1to 5 leaves fully extended in maize seedlings were investigated.The result showed that the chlorophyll content of maize leaves increased with the rise of leaf position.Compared with the leaf 1and 2,the leaf 4 and 5 had higher Fv/Fm and ETo/RC,which showed that the leaf 4 and 5 had stronger photochemical activity. |
