POMOLOGICAL AND CHEMICAL CHARACTERISTICS OF SOME BULGARIAN PLUM CULTIVARS

The Bulgarian plum cultivars ‘Goulyaeva’, ‘Balvanska slava’, ‘Gabrovska’, ‘Strinava’ and ‘Nevena’ were bred at the Plum experimental station in the town of Dryanovo.
These cultivars were studied in the period 2002–2006. Measurements taken were: yield, mechanical composition of the fruits, the content of dry matter, glucose, fructose, saccharose, organic acids, nitrogen, phosphorus, potassium, calcium and magnesium.
The plum cultivars ‘Goulyaeva’, ‘Balvanska slava’, ‘Gabrovska’ and ‘Strinava’ were highly productive.
Their yield surpassed 20 t/ha.
The fruits of the studied cultivars were large and very tasty.
The dry matter ranged from 19.17 to 23.10%. The fruits of ‘Strinava’ and ‘Goulyaeva’ had higher sugar contents.
The content of nitrogen in the fruits varied from 0.62 to 0.83%, phosphorus from 0.11 to 0.15% and potassium from 0.76 to 0.98%. The Bulgarian plum cultivars ‘Goulyaeva’, ‘Balvanska slava’, ‘Gabrovska’, ‘Strinava’ and ‘Nevena’ are productive, with large and tasty fruits and tolerant to some economic important diseases; they are suitable for propagation in plum growing regions in Bulgaria.
