Abstract
The correct choice of cultivar and rootstock, along with appropriate pre-harvest treatments, can greatly improve fruit quality.
In intensive fruit production, the use of bioregulators regulates numerous physiological processes in fruit trees.
This achieves better fruit quality, regulates fruitfulness, and controls tree vigor.
The aim of the research was to examine the impact of bioregulator application on apricot fruit quality depending on the rootstock.
In the apricot cultivar ‘Big Red’, grown on rootstocks Prunus cerasifera Ehrh. (myrobalan)/Stanley and Prunus domestica L. (belošljiva), treatments with GA3 200 ppm, NAA 10 and 20 ppm, BA 50 and 100 ppm applied four weeks after full flowering (average fruit diameter 13 mm). The treatment effect on fruit quality depended on the rootstock chosen.
A better impact of the treatment on fruit weight was achieved on the rootstock Prunus cerasifera. For all treatments except GA3, greater fruit weight was achieved than in the control.
For the belošljiva rootstock, only the application of NAA 20 ppm resulted in greater fruit weight.
A positive impact on fruit firmness was observed with BA treatments applied to both rootstocks.
Based on the results, it can be assumed that bioregulators could be applied in intensive apricot fruit production when proper cultivar and rootstock selection are used.
