[Spectrometric determination of trace elements in 'Jinguang' prunus mume var. bungo of different growth periods].

A study was carried out on the content of trace elements such as Ca, Fe, Zn, Mn and Cu of prunus mume var. bungo in different growth periods by WFX-110 atomic absorption spectrometry. The results indicated that the linear relationships of different elements within the limits of working curves are good and the range of the recovery is 98% -105%, hence showing that the results are satisfactory. The total content of these five trace elements increases as the fruit grows, but the concentration is related to the growth of fruit and fruit core, which provides us with valuable data. The contents of the trace elements essential to human body are relatively high, which shows that this fruit breed has a relatively high nutritive value.
