Seasonal changes of mineral elements in leaves and fruits of Whangkeumbae

This paper reported the seasonal changes of nine mineral element contents in the leaves and fruits of Whangkeumbae.The results showed that the contents of N、P、K in the leaves manifested a decreasing tendency in a year,the content of Ca showed increasing tendency,the content of Mg increasing in early period,decreasing in late period.The content of N、P、K、Ca、Mg in fruits manifested a decreasing tendency from setting fruit to harvesting.The contents of Mn and Cu in leaves and fruits showed a decreasing tendency.But Fe,Zn contents changed largely.The mineral elements in fruits and leaves have some correlations.
