Opis:
The current survey aimed to study the effect of exogenous salicylic acid (SA) application on salinity stress of grapevine cv. ’Sultana’. The leaves of hydroponically cultivated grapes that were under 0, 75 and 150 mM salinity conditions treated with 0, 0.5, 1 and 1.5 mM SA and after two weeks, the factors such as Na+, K+, proline and MDA contents, leaf electrolyte leakage and enzymatic activities were measured. The results showed that all SA treatments were significantly effective at tolerance enhancement by reduction in Na+/K+ ratio, leaf electrolyte leakage, MDA and H2O2 values and promotion in proline content and the enzymatic activities (POD, APX, CAT and SOD) of grapes. These results indicated that SA application at salinity condition could be applied as a promising method for increasing the salinity tolerance of ‘Sultana’ grapes.

Opis:
The study shows genetic diversity of 38 Vitis vinifera L. cultivars and hybrids originating in North America and Europe, including cultivars selected in Poland, which have not been characterized with the use of DNA markers yet. The agrobiological features of the genotypes selected for testing indicate that they may be useful for the breeding of new cultivars and grape production. The use of 12 ISSR primers allowed to obtain 94.4% of polymorphism. The polymorphic information content (PIC) value was high and varied between 0.829 and 0.953 with an average of 0.897. The resolving power (Rp) ranged between 3.678 and 8.892 with an average of 6.347. Primers UBC 809, UBC 810, UBC 812, UBC 855, UBC 891 and UBC 810 were found to be highly effective (informative). Similarity coefficient ranged between 0.167 and 1.0, which indicates high degree of diversity of tested grape cultivars. Tested cultivars were grouped in 3 main clusters; one of them was further divided into 6 subclusters. ‘Pannonia Kincse’ and ‘Danmarpa Polonia’ were not differentiated. Phenotypic differences among those two cultivars suggest that ‘Danmarpa Polonia’ might be a clone of ‘Pannonia Kincse’ and other molecular techniques must be used to differentiate them. Morphological and agrobiological characters of cultivars support the results obtained by ISSR markers.

Opis:
Nutrition of grapevines is very sensitive issue in vineyards. Soil quality is very important matter for growth and quality in vine growing. Rootstocks affect the growth and productivity of grapevine as well as increase or decrease of the nutrient uptake. The present study was conducted to determine the phenological changes of nutrient uptakes in 10 years ‘Trakya İlkeren’ grape variety (Vitis vinifera L.) in the heavy clay soil conditions. The grapevines are grown on 5BB and 5C rootstocks. The changes of macro and micronutrients in leaf blades from bud burst to post harvest period were investigated in the experiment. Leaf nutrient contents of leaf blades show varied depending on the phenological stages and rootstocks (P < 0.01 and P < 0.05). Nitrogen and phosphorus content of leaf blade was decreased until veraison stage for both rootstocks. The highest potassium (K) content was obtained at blooming stage. In blooming stage nitrogen (N), phosphorus (P), potassium (K) and magnesium (Mg) nutrients was found high on 5C rootstock whereas calcium (Ca) was high on 5BB. Grapevines were found insufficient for P, K and Mg nutrients in the study. Total chlorophyll and chlorophyll a/b ratio showed significantly varied among to rootstocks and phenological stages (P < 0.01). While the highest leaf chlorophyll content was measured during flowering period it was found at the lowest through to harvest on both rootstocks. Overall total chlorophyll contents and chlorophyll a/b ratio were significantly higher on 5BB grafted vines. In the research, 5C was found to be more successful rootstock than 5BB for nutrient uptakes.

Opis:
Fruit production should be adapted to future scenarios that are frequently associated with scarce resources, especially freshwater and fertilizers. New biologically-based fruit production strategies, i.e. taking into account tree growth and water status, are required to optimize irrigation and fertilization under abiotic stress conditions. It was hypothesized that a moderate abiotic stress, here deficit irrigation with or without nitrogen deficit, in the preharvest period, could decrease postharvest losses due to diseases and pruning weights due to reduced vegetative growth, without sacrificing the yield and fruit quality. This study was conducted over two years using the same trees of ‘Moncante’ nectarine cultivar grown in a commercial orchard. Trees were assigned to three treatments: (1) full irrigation at 80% estimated crop evapotranspiration (ETc), (2) deficit irrigation, i.e. at 75% of full irrigation, and (3) deficit irrigation and deficit nitrogen, i.e. at 75% of full irrigation and 75% of usual N-fertilization adopted by the grower in this commercial orchard. Deficit irrigation alone and in combination with deficit nitrogen reduced postharvest diseases and pruning weights without significant yield losses. Our results suggest that ETc-based approaches of reduced water irrigation may be a sustainable way to decrease phytosanitary inputs and workload in the orchard while maintaining the orchard performance.

Opis:
A present study was conducted to determine the impacts of organic and organo-mineral fertilizers on total phenolic, flavonoid, anthocyanin and antiradical activities of Okuzgozu (Vitis vinifera L. cv.) grapes. Study treatments included organic fertilizers (green fertilizer (vetch), green fertilizer (barley), green fertilizer (vetch + barley), farmyard manure, bactoguard, lifebac NP, humanica) and organo-mineral fertilizers (bactolife quality organo, bactolife high organo, bactolife high organo, bactolife super organo power). The control treatment did not receive any application. The organic, and organo-mineral fertilizers applications positively influenced the total phenolic, flavonoid and anthocyanin productions, and antiradical activity (DPPH). The maximum total phenolic production was significantly higher under Bactolife Super Organo Power (785.49 µg GAE/mg in pulp) application, followed by those under bactolife high organo 5-5-5 (780.40 µg GAE/mg in pulp). The total flavonoid production in berry skin (34.26 µg QUE/mg), pulp (137.00 µg QUE/mg) and seed (23.52 µg QUE/mg) were the highest under the bactolife super organo power whereas the antiradical activities (DPPH) of berry pulp and seed were at the maximum level under the bactolife quality organo treatment. Total anthocyanin content of berry skin and pulp of Okuzgozu grape cultivar was the highest under the organic humanica.

Opis:
The present study was conducted in 2014 vegetation season in a vineyard of Giresun Hazelnut Research Institute. Isabella (Vitis labrusca L.) grape cultivar were treated with four different boric acid (H3BO3) doses (control, 0.1%, 0.2%, 0.3%) at two different periods (a week before and after full-bloom). The effects of foliar boron treatments on yield, quality and leaf nutrients were investigated. Boric acid treatments positively influenced cluster weight, width and volumes and increasing values were observed with increasing boron doses. Boric acid treatments also influenced berry homogeneity and yielded more homogeneous appearance. Chlorophyll contents increased with increasing boron treatments. The greatest yield, cluster length, cluster volume, cluster size, cluster width, berry width and leaf area were obtained from 0.3% boric acid treatments. In general, leaf nitrogen, phosphorus, calcium, magnesium, zinc and copper concentrations increased, but potassium and iron concentrations decreased with increasing boron doses. As compared to control treatment, all treatments had broader leaf sizes and higher chlorophyll contents. Especially 0.3% boric acid treatments had quite positive influences on quality, size and color homogeneity. Considering the nutrients and pH level of experimental soils, it was concluded that foliar nutrient treatments may support plant growth and development and 0.3% boric acid treatments were recommended for high quality and quantity yields in Isabella grape cultivar.

Opis:
The effect on cell viability and content of PhC of three grapes varieties – Moravian Muscat, Blue Burgundy and Lemberger is presented. The effect of polyphenols from wine and grapes was studied for many times, but the effect of pomace, the by-product of wine production, was neglected. Thus study is devoted to compare the effect of berries and pomace on cell viability in context of their utilization as source of bioactive compounds. Effect on viability of human keratinocytes (HaCaT) was investigated in vitro using following concentrations of PhC in cultivation medium: 25, 50, 75 and 100 µg·ml–1. The results show that the content of PhC in berries and pomace was similar and the cell viability decreased with increasing concentrations of PhC, in most cases. The impact on cell viability also depends on individual variety of grapes.

Opis:
This study focused on examining the effect of vegetables extract foliar application on storage quality of the grapes grape (Vitis vinifera L. cvs. ‘Perlette’ and ‘King’s Ruby’). The vines were sprayed after fruit set twice at 15 days interval at concentrations of 0, 0.20%, 0.30% and 0.40%. Fruit were harvested and kept under cold-storage at 0.5 ±0.5°C and 90% RH for 28 days. The physicochemical properties of treated and untreated berries were analyzed at 7 days intervals during the cold storage. The results showed that the pre-harvest application of vegetable extracts reduced the weight loss and inhibited the fruit decay. Treated grape also had higher ascorbic acid contents, total phenolics, 2,2-diphenyl-1-picrylhydrazyl-radical (DPPH) scavenging activity, and higher soluble solid contents, titratable acidity, and reduced sugar:acid ratio. The concentration of 0.30% and cultivar ‘Kings Ruby’ gave the best result as compared to untreated control. In conclusion, pre-harvest vegetables extract application on berries showed higher antioxidant activities in grape berries, and maintained their post-harvest quality. These results indicated that foliar spray of vegetables extract could effectively improve the fruit quality, mainly through the reduction of phenolic content.
