Seasonal trends in the elemental content of plum leaves
The dynamics of eleven essential elements were studied in Golden Japan plum trees. Throughout the vegetative period the leaf concentrations of N, P and Zn fell. There was an accumulation of Ca, Mg, S, Fe, Mn and Cu, but there was no clearly defined tendency for K or B. The concentration of each element was time-related and correctly defined by a polynomial equation. It was found that the most suitable period to determine the nutritional state of the plum tree by means of foliar diagnosis was during the months of July and August. There was a good relationship between the nutritive state of the plant and the soil. The low foliar Mn content was thought to be related to these physicochemical properties which gives rise to and inadequate N metabolism.
