title: [Determination of nutrient elements in Jerusalem artichoke (J. A) irrigated by various concentrations of seawater by AAS].
abstract: The present study was carried out on the determination of trace elements in J. A by AAS, which has been irrigated by various concentrations of seawater and harvested in different years. The method is rapid with good precision and accuracy. Correlation coefficients were 0.997 1-0.9997. The result suggests that J. A is rich in K, Mg and Na, specially the ratio of K to Na is very high, and the content order is K>Mg>Na>Fe>Ni>Zn>Cu>Mn with Pb, Cr and Cd being lower. In addition, some trace elements are different in various J. A. So the authors conclude that the concentration of seawater has effect on trace elements. Perhaps the method is worth much more utilization.
