摘要

The effect of planting density and training system on vegetative growth of several apple (M. domestica [M. pumila]) cultivars (Idared, Golden Delicious and Jonagold and Elstar and mutants of the two) was studied at the Fruit Growing Centre Maribor-Experimental Station, Gacnik from 1992 to 1997. Trees were planted in a single-row system at 4 densities (2500, 5400, 6000 and 9000 trees/ha), a high-density, double-row system (16000 trees/ha), a traditional low-density, three-row system (3200 trees/ha)and a V-shaped system at two densities (3700 and 18000 trees/ha). Trees were trained as slender spindles or super spindles. Planting density affected trunk growth, leaf area, number of flower clusters, average fruit weight, number of fruits and fruit yield. Trunk growth increased with increasing planting density, from 2500 to 5400 trees/ha and decreased with increasing density, from 6000 to 18000 trees/ha. Leaf area per hectare increased with increasing planting density. With increasing planting density, yield per tree decreased, whereas cumulative yields per hectare increased. The average number of fruits per tree also decreased with increasing planting density. Increasing planting density decreased fruit quality (fruit weight, colour, soluble solids,sucrose, glucose, fructose, sorbitol, malic and citric acid).
