Determination of Metal Elements in Leaves and Petals of Different Color Saintpantia ionantha
The flame automatic absorption spectro photometry was used in the experiment to determine the contents of six metal elements ofNa, Mg, K, Ca, Fe and Cu in leaves and petals from the three different color cultivars ofSaintpantia ionantha. The test recovery rates are between 98.36 % and 103.13 %. The correlation coefficients are between 0.992 9 and 0.999 7. The results are as follow. In the three flower color cultivars, the content of Ca and Fe is higher in leaves than that in petals. On the contrary, the content of Cu is lower in leaves than that in petals, the content of Na is higher in leaves than that in petals in white and red cultivars and contrarily in blue cultivars, the content of K is lower in leaves than that in petals in white and red cultivars and contrarily in blue cultivars, and the content of Mg is lower in leaves than that in petals in white and blue cultivars and contrarily in red cultivars.
