Abstract

Abstract: To provide reference data for planting and cultivation, physiology and biochemistry research, and comprehensive exploitation and utilization of Pyrostegia venusta (Ker-Gawl.) Miers., the contents of K, Ca, Mg, Na, Fe, Mn, Zn, Cu, Cr, Ni were measured by the method of flame atomic absorption spectrometry (FAAS) in the vegetative organs and reproductive organs of Pyrostegia venusta (Ker-Gawl.) Miers.. The results showed that the order of the contents (average) of the 10 metallic elements in different parts was: K>Na>Mg>Ca>Fe>Mn>Zn>Cu>Ni >Cr. The content of the same element had certain differences among 14 measurement parts of Pyrostegia venusta (Ker-Gawl.) Miers.. In comparison with the general plant, the contents of K, Na, Mg, Ca, Fe, Mn, Zn, Cu, Ni and Cr in vegetative organs and reproductive organs of Pyrostegia venusta (Ker-Gawl.) Miers. mostly belonged to the normal range, except that contents of individual element of individual part were slightly more or slightly less than that in the general plants.
