Study of the influence of rootstocks on fruit flesh quality of three plum cultivars

The study of various rootstocks of the fruit species is most often associated with their influence on the growth and reproductive characteristics of the grafted cultivars.
Recently, with increasing production of fruits and their consumption as fresh or processed fruits, the requirements for the quality of fruit flesh have also increased.
In this regard, we investigated the influence of the rootstocks ‘G×N15’ (‘Garnem’), ‘GF677’, Myrobalan seedling, ‘Ishtara’ and ‘Wavit’ on the content of sugars, organic acids, polyphenols and anthocyanins in the fruit flesh of plum cultivars ‘Čačanska Lepotica’, ‘Stanley’ and ‘Jojo’. The study was conducted in southern Bulgaria near the town of Plovdiv.
The obtained results indicated that rootstocks did not have a significant influence on the basic parameters that shape the quality of fruit flesh in plum cultivars.
The cultivars included in the study have different values regarding the content of sugars, organic acids, polyphenols and anthocyanins due to their genotype.
