The impact of pruning techniques on the plant growth, yield components and fruit quality
traits of substrate-grown highbush blueberry (Vaccinium corymbosum) cultivar 'Bluecrop'
were evaluated over four years (2019-2022). The orchard was planted in the village of Gruža
(Knić municipality, Serbia) in the spring of 2017 with 5-year-old nursery plants using 113 l
polypropylene pots spaced 0.8 m apart in a row and 3.0 m between rows (4,170 plants/ha). At
the onset of the trial the ‘Bluecrop’ plants were 8 years old. The two pruning techniques were
applied: i) conventional pruning (CP) - removal of the most unproductive canes at the center
of the canopy, and weak and excessively fruiting shoots from the top of bushes, and ii)
sectorial pruning (SP) - only removal of basal canes in ¼ of the canopy each year. The
average number of basal canes per bush was significantly lower in SP than in the CP
treatment (14.4 vs. 17.4 canes bush-1
, respectively). SP plants had thinner cane...s than CP
plants, which increased over the years of the study and reached a maximum diameter of 11.12
mm in 2022. CP had a positive influence on fruit yield (5.98 kg bush-1
), which was associated
with a 20% higher number of fruits per bush than in sectorial pruned plants. The fruit yield
increased in the first three years of the study, reaching a maximum value in 2021 (7.57 kg per
bush), whereas an opposite trend was observed in average fruit weight over the years, with the
lowest value reached in the last harvest year (1.81 g). Fruit weight and soluble solids content
were not affected by the pruning method, while the content of total acids, total anthocyanins
and total phenolics were significantly higher in fruit harvested from the SP treatment (0.70%,
37.04 mg eq mvd-3-G /100 g FW and 1.18 mg eq GA/g FW, respectively) along with the total
antioxidant capacity (8.39 mg eq AsA /g FW).
