| Abstract: | Through phosphorus deficiency treatment,the phosphate content,photosynthetic pigment content,net photosynthetic rate(Pn),photochemical efficiency( F v/ F m),maximum fluorescence( F m)in leaves of umbilical orange decrease.However,the concentration of intercellular CO 2 and original fluorescence( F 0)rises,stomatal conductance( G s)change unsignally. |
