| Abstract:
Investigations of growth properties of plum trees cultivated on heavy soil were conducted during four years after planting (1997-2000). In experiment were three cultivars: Top, Elena and Felsina, grafted on rootstocks GF 655-2, Julior and Jaspy, and planted at three densities (3.8 x 1.8, 3.8 x 2.2 and 3.8 x 2.6 m). There was a general linear pattern of tree TCSA increment of ‘Felsina’, ‘Elena’ and ‘Top’ grafted on GF 655-2 rootstock from first to fourth year. In the fourth year trunk cross-sectional area decreased significantly as the distance within the row decreased. In fourth year crown volume of ‘Felsina’ was lowest whereas crown volume of ‘Elena’ and ‘Top’ was significantly higher. Different rootstocks had no influence on tree vigour of cultivars Felsina and Elena. | |
