[Changes of inorganic elements in senescent scales of Fritillaria thumbergii Miq. at the late stage].

By means of inductively coupled plasma-atomic emission spectroscopy (ICP-AES), the changes of inorganic elements in the senescent scales of Fritillaria thunbergii at the late stage were determined. The results showed that the main trends of the changes of P, S and K were continuously removing, while those of most elements such as Al were less removing. The inorganic elements for the growth of new organs were absorbed mainly from soil by the root.
