Abstract

Grey forest soils with heavy sandy clay structure and low nutrient availability are characteristic for the conditions of the region of Troyan. Climate conditions are the following: the average annual temperature is about 10°С and the annual rainfall is about 750 mm. The duration of vegetation period is 245 days. The experiment includes small-sized plum cultivars 'Tegera' and 'Elena', grafted on Mirobolan seedlings, and planted in 2000; and 'Katinka' grafted on 'Fereley' rootstock, planted in 2005, all are being grown under non-irrigated conditions. The aim is to determine the influence of soil and climate factors in the region of Troyan over the phenology and reproduction of the introduced German plum cultivars of 'Katinka', 'Tegera' and 'Elena'. The flowering, some vegetative and reproductive indicators were observed and chemical analysis of fruits was conducted for characterization of their taste qualities. It is found that in the foothill region of Troyan, plum cultivars find favourable conditions for growth and development, but they require regular agrotechnical
measures and increased attention in extreme climate changes. In 2015, which was a favourable year,the  plum harvest of 'Katinka' was about 40 kg per tree. Fruits had very small weight (15; 16; 21g), but the great quantity gave opportunity for high yield. The earlier ripening cultivars 'Tegera' and'Katinka' ac cumulate less dry matter in comparison with the late ripening cultivar 'Elena'.
