The programs for genetic improvement carried out in this country involved the selection of apple tree cultivars and rootstocks which enable a high fruit yield and quality, in order to meet the requirements from the consumer market. In the fertilization and irrigation management, nutrients and water ...
Forty apple rootstocks were evaluated during nine seasons for their influence on TCA (trunk cross-sectional area, cm), cumulative yield/tree (kg), cumulative yield efficiency (kg/cm), and biennial bearing index with 'Golden Delicious', 'Granny Smith' and 'Redchief Delicious'. Rootstocks varied...

Samples were collected at 0–20 cm depth, avoided fertilization sites and 1 meter away from tree trunk. Roots were dug up with the spade, shook off the large soil and put them into the sterile sealing bags. All trees were randomly distributed in the same orchard to give a complete ...

All test trees were established on apple seedling rootstocks. Budwood providing blotch inoculum was cut from the blotch-affected tree SB-1 used as an inoculum source in the original transmission tests. The tree was in a commercial orchard in which 49 of the 103 Stayman (Blaxtayman strain) ...

With this aim, six representative fruits from each tree were collected at harvest, and stored at 4 °C until the analysis. Two groups of three apples each were cut along the longitudinal and equatorial axis, respectively. The peel sides of the twelve halves together were photographed by a ...
(Trentino Alto Adige region). All the apple cultivars were planted in triplicate on M9 rootstocks and maintained following standard technical management procedures. Apple fruits were collected at the commercial harvest stage defined by monitoring the change of standard pomological parameters, such as ...
