| Abstract:
Plum trees of Prunus domestica cv. Dąbrowicka Prune grafted on seedlings and semidwarf rootstock Wangenheim Prune were planted in Spring of 1994 at 3.5 m spacing between rows and at a range of spacing within the row (1.0, 1.5, 2.0, 2.5 and 3.0 m) (2857, 1904, 1428, 1142, 952 trees per ha) and trained as spindle or hedgerow systems. Dense planting suppressed growth of trees and decreased yield per tree but greatly increased yield per hectare. Trees trained as a spindle produced higher yield than trees trained as a hedgerow system. In the fifth year after planting (1998) yield per ha varied from 30 to 44 t for hedgerows trees and from 41 to 66 t for spindle trees. The highest yields were obtained from the most densely planted plots. Planting density and training system had only a small influence on fruit quality. | |
