The researches performed at the Research Station for Fruit Growing Voineúti, in the period 2007-2011, had as object the study of 13 disease-resistant apple tree varieties, cultivated in the high density system, grafted on the graft bearer M 9, respectively: Ariwa, Golden Lasa, Goldrush, Enterprise, Inedit, Iris, Luca, Real, Rebra, Redix, Remar, Saturn, Voinicel, comparative with the Jonathan variety, taken as witness. The trees were planted at a distance of 4 x 1m (2.500 trees/Ha), spindle crown form. With high production potential remarked themselves the disease-resistant apple tree varieties Ariwa, Inedit and Saturn, which in the year 4 and 5 after planting realized over 30 t/Ha. In the same conditions, the apple tree varieties Real, Golden Lasa, Voinicel, Goldrush, Luca, Remar and Iris realized between 24.05 t/Ha and 26.7 t/Ha. The promotion of the high density apple tree system, in which disease-resistant apple tree varieties are previewed, represents a modality for periodical and rapid replacement of the assortments, leading to the identification of new modern technologies in obtaining of productions adapted to the requirements of the European quality standards.
