PHYTOGEOCHEMISTRY OF THE WILD ECONOMIC PLANT Corylus FROM THE EASTERN MOUNTAINOUS AREA OF TIELING, LIAONING PROVINCE

The wild economic plants of Corylus are collected from the eastern mountains area of Tieling, Liaoning Province. The main nutrition elements of P, K, Ca, Na, Mg and S, 14 kinds of nutrition microelements and rare earth elements (REEs) in Corylus are analyzed. The results show that the characteristics of main elements in the samples belong to the type of K > P > Ca. The greatest variation is found in Na concentration among the microelements, with variation coefficient of 44.27. The average contents of microelements are all in the normal scale of pant element contents. The mean microelement contents follow an order as Mn > Si > Fe >Zn > B > Cu > Ni > F > Cr > Mo > Co > Se > I > V. Among them, the element V is with the greatest variation coefficient (93.18). The gross of REEs, with mean value of 29.66×10^-9, belong to the low content level. The correlation analysis of element concentration in Corylus reveals that, at the level of 0.01, correlations exist between K and Na/Mg, S and Mg/Ca, P and K/Na/Mg/Ca, Fe and Mn, Co and Mn, and Cu and Zn. The results suggest a well cooperating effect on absorbability and accumulation among the elements.
