THE INFLUENCE OF PLANTING DENSITY ON THE GROWING AND BEARING PROCESSES AT FLORINA AND GENEROS CULTIVARS

Abstract

The promoting of the apple growing in high density system represent a continuous activity of great interest also in Romania but also in the foreign countries with advanced fruit growing. At the Fruit Research and Development Station Bistrita in the year 2000 it has been established an apple orchard with the cultivars Generos and Florina, grafted on the rootstock M26. The researches have been effectuated on trees planted at two densities: 1666 and 2500 trees/ per hectare. The training system of trees were slender spindle .The establishment of the experience was in randomized blocks with three repetitions. Every year there have been effectuated measurements of trunk girth , shoot length and after going into bearing , the weighing of the fruit production per tree and calculated per hectare. As a result of the performed researches, the obtained results show a productivity increasing at the Florina and Generos cultivars correlated with the increasing of the planted fruit trees number per hectare.
