Aim of this study is to investigate the interrelation between ethylene production, DA index (I AD), and postharvest treatments in four apricot (Prunus armeniaca L.) cultivars: 'Buda', 'NS Kasnocvetna', Rodna', 'NS6'. Apricots were harvested with I AD values 0.41-0.80, stored at 1 °C for 15 days, followed by 3 days shelf life room temperature. Ethylene production measured harvest, after cold storage, life. Preharvest included nitrogen (N) calcium (Ca), while modified atmosphere packaging...

Recycling organic waste is most important for preserving natural resources. The research objective was to quantify the effect of application vermicompost and leachate on yield quality strawberries compare it with a standard fertilization program mineral fertilizers during 3-year production cycle. Five treatments were studied: control—without fertilizer (Ø); (V); + foliar (VL); through fertigation (L); NPK (NPK). V positively affected strawberry only in first year. In all three years...

The objective of this research was to quantify the effect application organic fertilizers: farmyard manure, vermicompost, spent mushroom compost, under two different ground cover management systems (black polyethylene and wheat straw mulch) on soil nutrient levels strawberry yield during a two-year production cycle.The fertilizers, in amounts equivalent 170 kg ha -1 N, had greatest impact concentration available phosphorus, which significantly higher fertilized plots than control even years...

Fruit quality of Granny Smith apples picked at different harvest times and treated with 1-MCP.

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...

Ammonium and potassium thiosulfate are used commercially or experimentally as flower thinners because they considered user, environment consumer safe. The thinning trials were conducted in 2009 2010, on three- four-year-old Braeburn Mariri Red* trees. chemicals applied at 1%, 2% 3% rates of ammonium 0.5%, 1% 1.5% thiosulfate. Both agents reduced fruit set, but more efficient 2009, when 20% full bloom, than 80% bloom. Flower with increased the average weight, highest chemical retarded growth....

Growing the sweet cherry on different vigor rootstocks, such as Colt and Gisela 5, in a high-density orchard, causes differences growth productivity later imposes need to change growing system including pruning, flower fruit thinning, irrigation fertilization. In present research, four cultivars (Summit, Kordia, Lapins Regina) grafted 5 rootstocks were assessed for morphological traits productivity. The parameters investigated were: vegetative growth, bearing potential, set, precocity,...

Plant growth regulators (PGRs), such as cytokinins (6-benzyladenine; BA) and gibberellins (GAs), are widely used in fruit production. This study focused on the plum cultivar “Čačanska rodna” (P. domestica L.) grafted vegetative rootstock “WaVit” generative Prunus cerasifera, with interstock spinosa. PGR treatments included 50 mg L−1 100 of BA 200 gibberellin A3 (GA3) non-treated control. Pomological characteristics fruits were examined at harvest, while physicochemical properties analyzed...

A trial was conducted to determine biological and pomological traits of raspberry cultivars grown in western Serbia region (2003-2006) with the aim introduce those most desirable properties into production. The studies included morphometrical fruits, i.e. number drupes seed mass, as well yield viz. yields per shoot, meter unit land area. Fruits cv. Tulameen selection K 81-6 (4.28 g 4.11 g, respectively) were larger than Willamette (3.40 g) which, this respect superior cvs Meeker (3.29 Latham...

Abstract To overcome difficulty in phytopathogenic fungi control during storage of apple fruits, the effect different conditions on occurrence and development Fusarium avenaceum Alternaria alternata infections cultivar “Cripps Pink” was investigated after storage. Inhibitory effects wild oregano essential oil fruit rots caused by F. A. were also tested as possible rot measure. Artificially inoculated fruits kept cold with normal (NA) controlled (CA) atmosphere for 95 days at room temperature...

The general aim of this research was to determine whether the cherry root cambium possesses similar water-stress adaptation abilities as scion. Specifically, study aimed there is a shift in xylem structure due precipitation fluctuations and temperature increase during growing season two species. Oblačinska sour European ground roots with secondary were anatomically surveyed detail, correlated meteorological conditions occurring vegetation when formed. Under environmental signals, both...

During the cold storage of sweet cherry, severe losses can occur due to water loss, phytopathogenic fungi and physiological disorders. The aim this research was assess effects treatments with NAA (α-naphthaleneacetic acid), BA (6-benzyladenine), GA3 (gibberellic acid) on fruit quality at harvest after 21 days under two regimes, including 0°C, RH (relative humidity) 90% 3°C, 70%, additional shelf life exposure. Sweet cherry cultivars – ‘Summit’, ‘Kordia’ ‘Regina’ were treated bioregulators...

The aim of this research was to determine the influence drip fertigation on soil chemical properties and vertical distribution nutrient in root zone three apple orchards planted soils with different textures (loam, clay loam sandy loam). led a significant decrease pH, concentration calcium carbonate (CaCO3) organic carbon (C). Changes these parameters were more pronounced than loam. Fine textured (loam loam) had higher accumulation available forms P, K, Fe, Zn, Mn Cu surface layer at 0-10 cm...

The latest trends in hazelnut production are moving the direction of selection and breeding more productive cultivars, isolation native clones, intensive clonal rootstocks aimed at enhancing agronomic performance plants. Serbia stands out quality planting material by grafting on Turkish filbert (Corylus colurna L.), which does not form shoots develops a tree. aim this research was to investigate success achieved leading Italian cultivars (Tonda gentile romana, Tonda di Giffoni, Gentile della...

DA-meter enables quick and non-invasive determination of fruit ripeness in different types fruit, including apricots. In order to examine the postharvest physiology apricots, fruits were divided into five IAD categories (0.00; 0.01−0.40; 0.41−0.80; 0.81−1.20; >1.20) analyzed terms physicochemical sensory properties at harvest, after 21 days cold storage 3 shelf life. The specified differed ethylene production, flesh firmness, skin colour, composition harvest. After life, production...
