A wide range of bottle gourd Lagenaria siceraria (Mol.) Standley germplasm was collected from different parts the world. Genetic resource preservation and determination genetic variability carried out as a foundation for future breeding work. The diversity in Serbia is result its adaptation to diverse ecological conditions farmers? selection accordance with their preference ethnobotanical utilization. broad intraspecific variation plant, fruit seed morphology direct research out. Principal...

Several field collecting trips in the 2009-2011 period confirmed that forest fruit species are an inexhaustible genofond of extremely important varieties yield excellent quality and high nutritive value, with wide range applications, including nutritional, medicinal food production. The aim this work was to develop long term interactive integrated strategy for selection wild through different breeding methods, as well popularization selected products their integration into intensive growing....

SummaryThe search for growth-reducing rootstocks has produced selections of 'Oblačinska' sour cherry (Prunus cerasus L.) and European ground fruticosa Pall.). The methodological approach to germplasm collection was a compromise between specific characters random sampling the population. On principle 19 variables in 27 accessions, this research brought valuable diverse plant material into rootstock breeding. vigour adult trees on their own roots ranged from extremely weak, such as (SV1, SV3,...

Abstract Chemical properties ( L -ascorbic acid and total sugars content, pH, titratable acidity, dry solid content), phenolic compounds (total phenolics, tannins, flavonoids, anthocyanins, flavan-3-ols) antioxidant capacity were measured in ripe fruits of wild-growing strawberry, bilberry, elderberry from eastern Serbia. All three selected are rich sources nutraceuticals: vitamin C, sugars, different classes their extracts expressed high activity. Elderberry possess highest concentration...

The domestic population of walnut (Juglans regia L.) in Serbia is highly heterogeneous as a result many centuries propagation from seed. This paper describes variation observed this over the past four decades. date budbreak showed 50-day range, and leaf drop 32-day range. Average nut weight ranged 3.3 g to 29.0 kernel percentage 26.2% 64.3%. number female flowers per inflorescence 1 32 nuts cluster 15. majority Serbian seedlings had inferior traits, although few genotypes with excellent...

The paper presents a protocol for micropropagation of Prunus sp. rootstocks included in the sweet and sour cherry breeding program. Germplasm diversity rootstock derives from natural populations, where conditions biological vectors systematic infection with viral diseases are constantly present. establishment aseptic culture depends primarily on explant type, as all selections were collected habitat. For nearly investigated selections, dormant buds favored source, due to enabling rosette...

SummaryMultiple shoots and roots were regenerated from Williams bon Chretien (Bartlett) pear cotyledons excised two weeks before harvest cultured in vitro on an MS-based medium. The highest frequency of shoot organogenesis was obtained a medium supplemented with 5 mgl−1 BAP 0.1 NAA. Replacement NAA mg l−1 IAA reduction concentration to 3 increased the root at expense production. With as sole hormone supplement both production decreased. addition 2,4-D l−l completely prevented production,...

Self-fertile cherry cultivars can produce an excessive crop of small fruits with low sugar content. In order to prevent overcropping and provide high quality fruits, chemical thinning flowers is required. Ammonium thiosulfate (ATS), surfactants plant oils are used thin flowers, mostly in apple peach. The purpose this research was compare the effectiveness blossom thinners ATS, surfactant Silwet rapeseed oil (Ogriol) reducing fruit set self-fertile sweet Alex Sunburst their potential improve...
