AB  - The influence of three clonal rootstocks ('Pixy', 'Fereley', and 'St. Julien A') and one seedling rootstock ('Myrobalan') on tree vigor and productivity of three table plums cultivars ('Èaèanska Rana', 'Èaèanska Lepotica', and 'Èaèanska Najbolja') was examined in the region of Belgrade over a period of three years (2013-2015). Trunk crosssectional area, number, and length and weight of shoots removed during summer pruning were used as vigor indicators, while fruit set, yield tree-1, and cumulative yield efficiency were used as productivity indicators. Rootstocks exhibited a significant influence on tree vigor and productivity of the tested cultivars. The lowest values of the vigor indicators were found on 'Pixy' rootstock for all cultivars, and the highest values were found on 'Myrobalan' seedling rootstock. Based on the results obtained, 'Pixy' can be classified as a dwarf rootstock, 'Fereley' and 'St. Julien A' as medium vigorous rootstocks, and 'Myrobalan' as a vigorous rootstock. The fruit set was highest on 'Fereley' rootstock (on average 19.1% for all cultivars), while on the other three rootstocks it had lower values ranging from 16.4-17.1%. The highest yield tree-1 was obtained on 'Fereley' rootstock (on average 20.33 kg for all cultivars), then on 'St. Julien A' (18.50 kg) and 'Pixy' (16.09 kg), while the lowest yield was obtained on 'Myrobalan' seedling rootstock (15.62 kg). Cumulative yield efficiency was also the highest on the rootstock 'Fereley' (on average 1.05 kg cm-2 for all cultivars), and the lowest on 'Myrobalan' seedling rootstock (0.71 kg cm-2).

AB  - Chilling requirements for breaking dormancy and heat requirements for flowering were studied in 10 apricot cultivars in the region of Belgrade during a 2-year period. Chilling requirements were determined using the Utah chill unit (CU) model. To determine the date of dormancy breaking, 1-year-old shoots were collected weekly from December to February and kept under controlled conditions. Heat requirements were calculated as growing degree hours (GDH) accumulated from the breaking of dormancy to the beginning of flowering using a base temperature of 4 degrees C. The cultivars studied showed a range of chilling requirements, from 834 CU in 'Ninfa' and 'Goldrich' to 1442 CU in 'Re Umberto'. The heat requirements for flowering ranged between 2624 GDH in 'Magyar kajszi' and 3469 GDH in 'Tomcot'. The latest flowering cultivar ('Re Umberto') finished dormancy 42 days after the earliest flowering cultivar ('Ninfa'). The results indicate that flowering time of apricot in the studied region is influenced more by chilling requirements than by heat requirements. Identification and selection of cultivars with higher chilling requirements and later flowering is important for apricot production, especially in regions with the frequent occurrence of late spring frosts.
