THE STUDY OF SOME DISEASE – RESISTANT APPLE CULTIVARS, GROWN IN NORTH-WESTERN ROMANIA ON A PHREATIC WET CHERNOZEM
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
The cultivation of apple may be super-intensified by planting trees at close distance (4/2, 4/1, 3/2, 3/1 m) on a phreatic wet chernozem and managing the trees in palmetto system, orienting the branches in row direction. As ripening period, Romus 3 is harvested within 10 – 20 of July, being a summer variety, and the others after the 20th of September. Florina, Auriu de Bistriţa and Liberty cultivars obtain medium production of 48.2 t/ha, 45.5 t/ha and 42.0 t/ha over the three years of study. Except for the Romus 3 variety, all other varieties fall into groups with large and very large fruits. The weight index varies between 114.2 g in case of Romus 3 variety up to 186.7g in case of Florina variety. Fruit quality planted at a close distance is insignificant, influence by reducing their size. Values of the dry substance above 12% are present in case of Florina, Liberty and Romus 3.
