The study was conducted in two successive years to examine the capacity of formation of sylleptic shoots in nursery trees of ‘Abbé Fétel’, ‘Conference’ and ‘Starking Delicious’ pear cultivars grafted on quince MA and quince BA 29 rootstocks during the first year after bud grafting. Tree height, trunk diameter – 10 cm above the bud union and number of sylleptic shoots were measured at the end of each season. Tree height was measured from the ground level. The greatest number of sylleptic shoots was registered in ‘Abbé Fétel’ in both seasons, and the smallest in ‘Starking Delicious’. Tree height and tree diameter were highly significantly affected by cultivar in both years and by rootstock in 2008. The interactions between them did not significantly affect the examined parameters. The study showed that the early growth and syllepsis of pear nursery trees during the first year after bud-grafting were incomparably more affected by cultivar than by rootstock.

During 2012 and 2013 we investigated impact of quinces MA and BA.29 rootstocks on leaf macro- and micronutrients amount at 60 days after full bloom (DAFB) and deviation from optimum percentage (DOP and ΣDOP indexes) of three pear cultivars grown at Cacak region on heavy and acidic soil. Results showed that rootstocks significantly influenced leaf P, Ca and B levels, whereas impact on other leaf nutrients is minor. Quince MA increased leaf P and Ca contents, while BA.29 induced higher leaf B level. Stronger effect than rootstock on leaf nutrients had cultivar, although differences among them for leaf N, Mg and Fe were not significant. Leaf of ‘Abbé Fetel’ on BA.29 had the highest K, Ca, Cu and B amounts, whereas on MA this cultivar had the highest Mn concentration. Also, ‘Abbé Fetel’ alongside with ‘Conference’ on MA had the highest and similar leaf Ca, Cu and Zn amounts. ‘Starking Delicious’ on BA.29 had the highest leaf P content. The DOP index showed high deficiency of K and Mn on both rootstock and Ca on BA.29. Other leaf nutrients tended to have a DOP values close to the optimum level in general. According to ΣDOP index, BA.29 induced better balanced leaf nutritional values as compared to MA for all nutrients. Among cultivars, ‘Abbé Fetel’ on both rootstocks and ‘Conference’ on BA.29 showed the best balanced nutritional values, whereas ‘Starking Delicious’ exhibited a wider imbalance in nutritional values for all nutrients.

Prunus domestica L. is the most important fruit crop in the Europe and the most important within the genus Prunus. Serbia is the third world producer, after USA and China, of that friut. The seven F1 plum genotypes (Prunus domestica L.) which originated from three cross-combinations (‘Čačanska Lepotica’ ב Stanley’, ‘Čačanska Najbolja’ ב Stanley’, ‘Stanley’ ב Stanley’) and these cultivars as controls were planted in the experimental orchard in Prislonica, near Cacak, in spring 2000. In 2005–2007 several biological (blooming period, harvest date and yield) and main fruit quality traits were evaluated. Considerable variation was observed among the F1 genotypes, i.e. cross-combinations. All genotypes begun blooming later than their parents. The earliest harvest date was observed in ‘P4’ and the latest in ‘P7’. The highest yield was observed in ‘P5’. The genotype ‘P4’ had better values for some fruit quality traits (fruit weight, fruit rate, flash rate, fruit height, suture diameter, cheek diameter, soluble solids, fructose and total sugars content), when compared with other F1 genotypes and control cultivars. The genotypes with better biological and fruit quality traits were included in the ‘Čačanska Lepotica’ ב Stanley’ cross-combinations.

The study has been based on a three-factor field experiment (two rootstocks – Myrobalan and Stanley seedlings, two cultivars – Èacanska lepotica and Èacanska najbolja, three years – 2006, 2007 and 2008) set up according to the method of randomized blocks with four replications. The aim of this work was to evaluate the mineral composition of plums in Serbia. The results indicated that levels of fruit ash and minerals, except nitrogen, significantly differed between the treatments. The average content of ash in plum fruits reached 4.54%, nitrogen – 0.78%, phosphorus – 0.06%, potassium – 1.45%, calcium – 0.07%, magnesium – 0.16%, iron – 19.37 μg g–1, manganese – 10.21 μg g–1, copper – 3.21 μg g–1, zinc – 19.29 μg g–1 and boron – 22.83 μg g–1 of dry matter. A strong rootstock/cultivar/year interaction was found for most of the minerals. Between ash and manganese or zinc, and between manganese and zinc in plums, significant correlations were observed. On the basis of the analysis of major components, we concluded that Stanley rootstock had better ability to accumulate ash and most of the minerals in fruits of both cultivars than Myrobalan rootstock.

Nut and kernel size, shape and some sensorial traits in ten hazelnut (Corylus avellana L.) cultivars were evaluated using an objective procedure based on multivariate analysis in order to obtain an important value of these cultivars for growers, processing and consumers. Cultivars were compared with nuts and kernels of C. avellana L. and C. colurna L. Significant differences in all physical properties were found among the cultivars, and also among cultivars and hazelnut species. A high correlation was found among some hazelnut traits. Cluster and principal component analysis supported results obtained by analysis of variance, and segregated genotypes in similar groups according to their characteristics evaluated. Procedure described may be useful in analyzing impacts of genotype per se on nut and kernel physical and sensorial properties, and also determine the factors for growers, breeders, especially for harvesting, sorting and other postharvest operations in order to establish optimal machine and equipment design.

The study focused on characterizing the three German plum cultivars (‘Jojo’, ‘Hanita’ and ‘Katinka’) hypersensitive (oversensitiveness) and/or tolerant to Sharka to acknowledge the tree vigour, precocity, yield performances and main physico-chemical quality attributes of the fruits grown in a Serbian agro-climatic conditions. The cultivars were grafted on ‘Wangenheim Prune’ seedlings rootstock and established at a 4 × 1.5 m. The following determinations were assessed: trunk cross sectional area, yield per tree and unit area, yield efficiency, fruit and stone mass, fruit linear dimensions, flesh rate, geometric mean diameter, sphericity, aspect ratio, surface area, soluble solids and sugars content, titratable acidity, and ratio between them, respectively. The cultivar per se (genotype) behaved as the most influencing factor conditioning plum tree vigour, yield characteristics, physical attributes, soluble solids content, titratable acidity and sugar profiles. The assessment of plum chemical compositions implies the great potential of German cultivars for fresh market, fruit processing and drying. In fact, the ‘Katinka’ seems particularly suitable for fresh consumption, whereas ‘Jojo’ and ‘Hanita’ can be recommended for fresh consumption, processing and drying. Finally, all three cultivars grafted on ‘Wangenheim Prune’ seedlings can be recommended for growers in similar conditions.

Mineral nutrition of apricot is very specific and depends on different factors such as soil fertility, soil pH, weather conditions, cultivars, rootstocks, fertilizers, age of trees etc. For these reasons, during 2008 and 2009 we evaluate nutrient status of five apricot cultivars (Vera, Aleksandar, Biljana, Harcot, Roxana) at 120 days after full bloom (DAFB) grown on acidic soil in the region of ýaþak (Western Serbia). The results showed no statistically significant variations in the N, K and Ca content of apricot leaves among cultivars, as opposed to significant differences in the content of P, Mg, Fe, Mn, Cu, Zn and B. The ȈDOP index revealed that the average content of all macro- and micronutrients was below the optimum, except that of P in both years and that of Mn and Cu in the first year of the study. The insufficient nutrient supply of the test apricot cultivars requires adjustment of fertiliser types and application rates to this soil type according to foliar analysis.

The experiment was established at private apricot orchard near Cacak (Western Serbia) during 2010 and 2011. In the present study we wanted to determine the physicochemical attributes, phenolics content and antioxidant capacity of three new Serbian cultivars (‘Aleksandar’, ‘Biljana’, ‘Vera’) grafted on Myrobalan seedlings. Results indicated that physico-chemical attributes significantly varied among cultivars. Similarly, total phenolics and flavonoids content and antioxidant capacity significantly depend on the cultivars. Generally, new Serbian cultivars had better properties evaluated than control (‘Hungarian Best’), except stone weight, fruit firmness, moisture and total phenolics content. The highest values of total phenolics and flavonoids content were found in ‘Aleksandar’, whereas the highest antioxidant capacity was recorded in ‘Vera’. Finally, new Serbian cultivars could be recommended for planting in similar conditions and apricot growing programs.

Breeding of stone rootstock is very important problem for orcharding. In many countries of the world have been obtained a lot of new breeding material for sweet and sour cherries and plums. An analysis was conducted in Cacak (Western Serbia) in the 2006–2007 period to examine major morphological traits of the aerial part and root of suckers derived from mother bushes of three newly vegetative rootstocks for stone fruit species, particularly plum, peach and apricot trees. The newly breed rootstocks have been developed from autochthonous genetic material, their specific designations being: FA 2/53 (Prunus domestica L.), FA 5/7 (P. domestica L.) and FA 6/209 (P. cerasifera Ehrh.). The analysis of suckers of the new rootstocks included the investigation of morphological traits through the determination of: a) length of the aerial part, b) number of feathers on aerial part, c) number of roots, d) length of roots, and e) volume, weight and category of the roots. They developed branch roots and exhibited good length of the aerial part, a substantial number of roots and root dry weight. The FA 2/53 rootstock can be classified into low-vigour rootstocks, FA 5/7 into low to moderately vigorous ones (slightly more vigorous than the FA 2/53 rootstock) and FA 6/209 into moderately vigorous rootstock for stone fruits.

Fruit apricot dimensions, weight, size and shape are the most commonly measured pomological properties. The size and shape features of 13 apricot (Prunus armeniaca L.) cultivars and promising Serbian selections grown in Western Serbia were investigated using a multivariate analysis. The apricots promoted fruits wider than long in shape, except ‘Harcot’, ‘T 7’, ‘Précoce de Tyrinthe’, ‘Roksana’ and ‘Vera’, whereas all cultivars and selections are wider than thick. Most of cultivars and/or selections tend to round shape. Mean values for fruit and stone weight, flesh rate, geometric mean diameter, kernel weight, sphericity, aspect ratio, surface area and volume ranged from 37.09 to 81.60 g, 2.71 to 4.18 g, 91.93 to 96.46%, 41.76 to 65.08 mm, 0.60 to 1.17 g, 0.94 to 1.03, 95.04 to 108.09%, 55.13 to 133.77 cm2 and 38.31 to 145.10 cm3 , respectively. For the most of attributes evaluated, ‘Roksana’ had the highest values. A high correlation was found among some physical attributes. According to their 22 properties, the apricots grouped into five clusters. There was either relative independence or close correspondence among the evaluation indexes of apricot fruit quality. Principal components analysis showed that the first three principal components variance accumulation contribution rate amounted to 85.77%, which reflected most of the size and shape characteristics of apricots.

The study was conducted to determine the effects of Myrobalan rootstock and Blackthorn interstock on fruit physical and chemical traits of five apricot cultivars. The results showed that cultivars grafted on Myrobalan rootstock appear to induce a higher fruit mass when compared with the Blackthorn interstock. Blackthorn interstock showed a tendency to induce a higher soluble solids/titratable acidity ratio than Myrobalan. Values of soluble solids content, total sugars, titratable acidity and fruit firmness between Myrobalan rootstock and Blackthorn interstock were not significant. Regarding cultivars, the greatest fruit mass observed in Roxana in both treatments, and the lowest in Biljana on Myrobalan and in Vera on Blackthorn. The lowest soluble solids, total sugars and soluble solids/titratable acidity ratio were found in Roxana in both variants of grafting, whereas the greatest titratable acidity also observed in Roxana in both cases, respectively. Based on the results from this study, the fruits of Roxana can be recommended for fresh consumption, whereas fruits of the other cultivars can be recommended for processing.

A 3-year study was done to compare the blossoming and harvesting date, fruit physical and chemical composition of six nectarine cultivars grown with High Density Planting system under western Serbian conditions. A high variability among and within cultivars was found and significant differences were observed among them in all properties analyzed. Year-by-year variations were observed for blossoming and harvesting date, length of fruit growth, soluble solids content, fruit weight and fruit firmness. On the basis of evaluated data, the best fruit performance registered in ‘Caldesi 2000’ and ‘Syrio’ grown with HDP on heavy soil. Contrary, the poor fruit physico-chemical properties were observed in ‘Mayfire’, especially in ‘Nectared 4’. This evaluation may help to select a set of nectarine cultivars with better fruit quality attributes, which in our growing conditions might be indicated in ‘Caldesi 2000’, ‘Syrio’, somewhat ‘Weinberger’ and ‘Fantasia’.
