Abstract
Cherry is a valuable species for fruit growers due to its nutritional and commercial properties.
The priorities for cherry producers are to increase the quality of the fruits, such as size, appearance, firmness, aroma, sugar content, and acidity.
The aim of this study was to determine the influence of planting distances on some characteristics of cherries.
The study was conducted in the Experimental Field of the Research and Development Station for Pomiculture Baneasa to determine the influence of planting distances on quality indicators, including weight, height, small diameter, large diameter, pH, sugar content, and fruit firmness.
A bifactorial experiment was established where factor A was the cultivar with the following graduations: a1) ‘Regina’ and a2) ‘Sweetheart’, grafted on the Gisela 5 rootstock, with a slender spindle crown shape.
Factor B was the planting distance of the trees, with the following graduations: b1) 4×1.5, b2) 4×2.0, and b3) 4×2.5 m.
The planting distance between rows was 4 m, and the distances between trees on the row were 1.5, 2.0, and 2.5 m.
The determinations were made under the climatic conditions of the year 2022. Following the conducted study, the ‘Sweetheart’ cultivar’s determinations (weight, height, small diameter, large diameter, sugar, pH, citric acid) recorded higher values at the planting distance of 4×2.0 m.
For the ‘Regina’ cultivar, the highest average values of height, small diameter, and large diameter were recorded at the planting distance of 4×2.5 m.
The total sugar content of ‘Regina’ fruits was higher at planting distances of 4×2.0 m.
At the planting distances of 4×2 and 4×2.5 m, ‘Regina’ recorded higher values for all determinations performed, compared to ‘Sweetheart’ At variant b1, both cultivars had similar values for quality indicators; only the weight of the ‘Regina’ cultivar fruits was superior to the weight of ‘Sweetheart’ fruits.
For ‘Regina’, the average fruit weight was 9.25 g fruit-1, while ‘Sweetheart’ had a lower average weight of 8.02 g fruit-1. The results of the experiment led to the conclusion that planting distances influence fruit quality and the attainment of satisfactory yields, both quantitatively and qualitatively, thereby meeting the requirements of producers, the market, and consumers.
In this way, ‘Regina’ produced fruits of superior quality compared to ‘Sweetheart’ in terms of weight, height, small diameter, large diameter, sugar content, and pH.
