Apple tree growth and mineral elements content from the leaves of grafted apple trees, cultivated in a nursery, and the influence of chemical treatments

Abstract

We have compared the effect of four chemical treatments on fruit tree growth and mineral elements content from the leaves of two cultivars of grafted apple trees. The used foliar fertilizers have not significantly influenced the results of the growth of grafted fruit trees. However, they have considerably increased the number of flower buds and dwarf shoots of “Idared” cultivar. The Paturyl product has significantly increased the number of long shoots of “Jonagold” cultivar and the dwarf shoots of “Idared”, compared to the control. At the same time, it did not initiate the formation of flower buds. The effect of chemical treatments, applied through the foliage, on the content of mineral elements in the leaves of grafted apple trees was diverse.
