Abstract
This study was conducted to investigate the effects of germanium (Ge) application
types on the nutrient concentrations in soil and leaves and leaf characteristics in a
‘Niitaka’ pear orchard in 2004. Ge application included foliar application, fertigation
in soils, trunk injection, and the three-combined application. All Ge treatedplots
had lower soil NO3-N, K, and Ca concentrations than those of control plot.
Ge concentrations in Ge treated-soils were approximately 50 times higher than
those of the control. Ge applications significantly increased area, dry weight, and
specific weight in leaves compared to the control. Control treated-trees had greater
K concentrations in leaves than the Ge treated-trees, which was oppositively
observed for the leaf Ca; leaf Ca was higher on the Ge treated-trees than control.
Leaf Ge concentrations were significantly higher on the Ge treated-trees compared
to the control, except for the Ge fertigation. Ge concentrations in fruits were
greater on the Ge-treated trees than the control trees.
