Opis:
Vaccinium ×intermedium Ruthe, the hybrid of V. myrtillus and V. vitis-idaea, by contrast with the parental species is very rare plant and has a discontinuous geographical range in north-western Europe. This paper describes the morphology of V. ×intermedium from Polish populations occurring in part of Pomeranian Lakeland in comparison with both parent species. The results presented here confirm the suggestions of earlier research that V. ×intermedium displays intermediate characteristics of leaf and floral morphology concordant with hybrid status. Also, is discussed the problem of the isolating mechanisms between parent species and hybrid's ecology.

Opis:
The paper discusses the impact of clear−cutting and artificial regeneration on species composition of the fresh coniferous Vaccinio vitis−idaeae – Pinetum association Sokoł. 1981. The studies were conducted in the maturing artificially established stands (of 55−77 years) and 150−180 year−old natural old−growth stands in the Polish and Belarusian part of the Białowieża Primeval Forest. No quantitative and qualitative differences were found in species composition and structure between the two groups of stands. The lack of significant differences between the two development stages was ascertained using ecological indicator values. In the maturing stands the non−forest species were not found, and all species (so−called euphytes??), characteristic of the Vaccinio vitis−idaeae – Pinetum association, were already present there. This means that the use of a clear cutting system emulating the catastrophic natural disturbance pattern of forest dynamics in this association did not entail permanent changes in the ground vegetation.

Opis:
Wild berries of the genus Vaccinium have become increasingly popular in human health promotion due to their nutritional and medicinal properties. Some striking divergence of opinion about the content of triterpenoids in these plants still exists, meanwhile, this very large class of natural isoprenoids exhibits a wide range of biological activities and hence is of growing research interest. An investigation of triterpenoidal constituents from the cowberry (Vaccinium vitis-idaea L.) plant led to the isolation of two isomeric acids: oleanolic and ursolic and the occurrence of their derivatives in this plant was demonstrated for the first time. Free triterpene acids as well as small amounts of their bound forms (presumable glycosides and glycoside esters) occur in fruits and the vegetative part of the plant, however, in various amounts and different ratios. The total content of both acids was the highest in organs regarded as traditional herbal resources, namely fruits and leaves (1 and 0.6% of dry mass, respectively), whereas it was markedly lower in stems and rhizomes. However, the rhizomes were in turn the plant organ containing relatively the highest amount of the bound forms of both acids (0.01% of dry mass). Ursolic acid was dominant in the whole plant, but the ratio of oleanolic to ursolic acid was significantly different in individual organs, decreasing from the upper (fruits 1:2.4, leaves 1:2) to the lower (stems 1:3.5, rhizomes 1:5.2) parts of the plant. This pattern of distribution of triterpenoids in the plant may have an important physiological and ecological meaning.

Opis:
W pracy scharakteryzowano syropy z owoców żurawiny i brusznicy, otrzymane trzema zmodyfikowanymi metodami stosowanymi w gospodarstwach domowych, pod względem zawartości związków biologicznie czynnych (antocyjanów, polifenoli, witaminy C) oraz właściwości przeciwutleniających i barwy (L*a*b*). Modyfikacje metod otrzymywania syropów dotyczyły rozgniatania i podgrzewania owoców z cukrem. Ze względu na zawartość analizowanych związków oraz barwę uzyskanych produktów, najwłaściwszą modyfikacją uznano równoczesne rozgniatanie i podgrzewanie surowca. W przechowywanych syropach, do czwartego miesiąca zwiększała się ogólna zawartość związków fenolowych, a do ósmego miesiąca siła redukująca, będąca miernikiem właściwości przeciwutleniających. Zawartość pozostałych składników, w tym witaminy C, wyraźnie zmniejszała się. Antocyjany zawarte w brusznicy przechodziły do syropów w mniejszym stopniu niż zawarte w żurawinie i szybciej ulegały rozkładowi w czasie przechowywania.
In this paper, the cranberry (Vaccinium oxycoccus L.) and cowberry (Vaccinium vitis-idaea L.) syrups manufactured using three modified home methods were characterized with regard to their biologically active substances (anthocyanins, polyphenols, vitamin C), as well as to their antioxidant activity and colour (L*a*b*). The modifications in the methods of manufacturing syrups referred to squashing and heating fruit with sugar. Considering the content of the compounds analyzed and colour of the final product, the simultaneous squashing and heating of raw material was found to be the most fitting modification. In the syrups stored, their total phenolic content increased until the fourth month, and the reducing strength, an indicator of antioxidant properties, increased until the eighth month. The content of the remaining compounds, including vitamin C, significantly decreased. Anthocyanins contained in the cowberry passed into the syrups less effectively than those originating from the cranberry, and, also, they faster decomposed during the storage period.

Opis:
Grapevine seedlings Vitis vinifera were grown in a greenhouse under optimum conditions (soil moisture ca 70%) and under drought stress (soil moisture ca 35%). In addition, some of the plants subjected to drought underwent subsequent regeneration under optimum conditions. Drought stress caused accumulation of total phenolic compounds in grapevine roots, which may indicate that these compounds play an important role in the adaptation of roots to growth under stress conditions. Phenolic acids found in the roots occurred in the ester-bound form only. p-coumaric acid was present in the highest concentrations (6.2 to 10.5 µg/g fresh matter). The content of ferulic acid was lower, ranging from 2.4 to 4.6 µg/g fresh matter. The lowest concentration in grapevine roots was achieved by caffeic acid (2.4 to 2.9 µg/g fresh matter). The levels of p-coumaric and ferulic acids in roots rose significantly under the drought stress, while the concentration of caffeic acid increased during the post-drought recovery period. This may suggest that some of the phenolic acids protect plants under stress conditions. All the extracts from grapevine roots had antioxidative properties, but the antiradical activity of the extracts obtained from roots subjected to drought stress was inferior to the control. The same extracts were also characterised by depressed reducing power. The results imply that tolerance of grapevine to soil drought may be associated with the value of antioxidative potential in root tissues of these plants.

Opis:
The research has been performed on roots of Vitis vinifera, cv. Himrod, obtained from seedlings grown under chill stress conditions (+10oC in the day and +7oC at night), under optimum conditions (+25oC in the day and +18oC at night) and from seedling which underwent a recover period after the chill stress treatment. The purpose of the study has been to determine quantitative and qualitative changes in phenolic compounds as well as to demonstrate changes in antiradical properties of extracts from grapevine roots, which appeared as a result of chill stress and during recovery under the optimum conditions following the stress. Phenolic compounds from grapevine roots were extracted using 80% acetone. The total content of phenolics was determined by colorimetry. The content of tannins was tested by precipitation with bovine serum albumin. The reducing power as well as DPPH• free radical and ABTS+• cation radical scavenging activity of the extracts were also tested. In order to identify phenolic compounds present in the extracts the RP-HPLC technique was employed. The tested material was found to contain tannins and three identified phenolic acids: ferulic, caffeic and p-coumaric ones. The latter occurred in the highest concentrations (from 4.46 to 6.28 µg/g fresh matter). Ferulic acid appeared in smaller amounts (from 1.68 to 2.65 µg/g fresh matter), followed by caffeic acid (from 0.87 to 1.55 µg/g fresh matter). Significantly less total phenolic compounds occurred in roots of seedlings subjected to chill stress. However, the total content of these compounds increased significantly in roots of plants which underwent recovery after chill stress. Concentration of tannins was determined by two methods. The content of condensed tannins was depressed in roots as a result of low temperature stress, whereas the content of condensed and hydrolysing tannins (determined via the BSA method) rose under chill stress conditions. A significant increase in tannins in root extracts (determined with both methods) was found during the recovery process after the stress. The three identified phenolic acids appeared in grapevine roots as ester-bound compounds. It has been demonstrated that the content of phenolic acids significantly fell as a result of low temperatures, but increased during recovery after chill stress. The weakest ability to scavenge DPPH• and ABTS+• free radicals as well as the reducing power were shown by the extract obtained from grapevine roots from the seedlings subjected to chill stress. Both free radical scavenging activity and reducing power were observed to increase considerably during recovery after stress. This seems to prove that during the recovery process following chill stress the synthesis of antioxidative compounds in grapevine roots is much more intensive.

All studied climbers showed similar photosynthetic intensity in both sites. The strongest effect of the exposition was found for F. aubertii, followed by V. riparia, and shade tolerant H. helix. WUE of studied climbers was relatively low, higher in suburbs than in the centre, due to lower adaptation to different sites. TheWUE of the climbers depended on exposure and the highest scores were obtained for sunny southern and western walls, while the lowest in northern ones. Intrinsic water use efficiency of the studied climbers was higher in the city centre than in the suburbs.

Opis:
Winogrona (Vitis vinifera) są cenionymi owocami deserowymi, jednak ich atrakcyjność może ulec pogorszeniu, jeśli podczas dystrybucji i sprzedaży nie są właściwie zabezpieczone. Obecnie poszukuje się nowych metod pozwalających na zwiększenie trwałości owoców i zachowanie ich dobrej jakości w obrocie towarowym. Do takich rozwiązań należą ochronne powłoki jadalne. Celem pracy było określenie możliwości wykorzystania powłoki białkowo-woskowej do zabezpieczenia jakości winogron. Owoce poddano powlekaniu poprzez trzykrotne zanurzenie w wodnym roztworze zawierającym 10 % izolatu białka grochu, 5 % sorbitolu (plastyfikator) i 2 % wosku kandelila. Powlekane oraz niepowlekane (kontrolne) winogrona przechowywano w temp. 20 ºC i wilgotności względnej powietrza 40 % przez 11 dni. Badania wykazały, że po 11-dniowym przechowywaniu powlekane winogrona, w stosunku do niepowlekanych, wykazywały statystycznie istotnie większą zawartość kwasu askorbinowego i cukrów redukujących oraz mniejsze ubytki masy, co przyczyniło się do przedłużenia świeżości owoców. Powlekanie nie wpłynęło na zmianę kwasowości miareczkowej i czynnej winogron. Dodatkową korzyścią powlekania było nadanie owocom atrakcyjnego połysku.
The table grapes (Vitis vinifera) are highly valued dessert fruits, but their attractiveness can get worse if they are not properly protected while being distributed and sold. Presently, researches have been carried out to find new methods for increasing the life-shelf of fruits and maintaining their high quality while they are on the market. Edible coatings could be a potential solution to that problem. The objective of this study was to determine the possibilities of using protein-wax coating to protect the quality of grapes. Grape fruits were coated while they were three times immersed in an aqueous solution containing: 10 % of pea protein isolate, 5 % of sorbitol (plasticizer), and 2 % of candelilla wax. The coated and uncoated (control) grapes were stored at 20 °C, under 40 % relative air humidity, during a period of 11 days. The study showed that, comparing to the uncoated grapes, the coated grapes stored for 11 days had a statistically significant higher content of ascorbic acid and reducing sugars, and lower weight losses, which caused the freshness of the fruits to be kept longer. The coating did not cause any changes in the titration acidity and pH of the grapes. The additional benefit of coating was an attractive sheen of the fruit surface.

Opis:
The tested material consisted of grapevine Vitis californica stratified seeds germinated under optimum conditions (+25°C in water), under osmotic stress (-0.2 MPa in PEG solution) and submitted to recovery after stress (+25°C in water). The germinating seeds were determined to contain tannins, catechins and the following phenolic acids: gallic, caffeic, p-coumaric and ferulic. The acids occurred in free, ester- and glycoside-bound forms. The dominant form of phenolic acids was the ester-bound fraction. Gallic acid was the most abundant phenolic acid in germinating seeds, while ferulic acid appeared in the smallest amounts. Our analysis of tannins demonstrated that osmotic stress depressed their concentration. Presence of catechin group compounds such as catechin and epicatechin was also determined. In each sample epicatechin was dominant. The total concentration of catechin increased under stress conditions and declined during post-stress recovery. Catechins are a constituent of tannins and their increase under osmotic stress is most probably caused by the breakdown of some tannins in seeds germinating under stress conditions. Samples submitted to osmotic stress were also found to contain less of total phenolic compounds, whereas in samples which underwent post-stress recovery the total level of phenolic compounds increased. Compared to extracts from seeds germinating under optimum conditions, osmotic stress depressed the capacity of extract to scavenge DPPH● (2,2-diphenyl-1-picrylhydrazyl) and ABTS●+ – 2,2-Azino-bis (3-etylbenzothiazoline-6- -sulfonic acid) free radicals, but the antioxidant activity rose in seeds submitted to recovery after stress. Positive correlation was therefore demonstrated between the total content of phenolic acids in germinating grapevine seeds and the reducing power of extracts obtained from these seeds and their free radical scavenging activity. The results suggest that osmotic stress inhibits the activity of antioxidizing enzymes in germinating grapevine seeds. Thus, the antioxidative defence system is largely blocked under osmotic stress. It seems that a very high oxidoreductive potential in grapevine tissues prior to occurrence of osmotic stress is essential for maintaining proper homeostasis of oxidation and reduction reactions.

Opis:
The response of berry organic acids of four organically grown table grape cultivars to cane-girdling and cluster-berry thinning treatments were evaluated over two growing seasons. In addition pH, titratable acidity, soluble solids content and maturity index were also determined. Statistical analyses showed that individual organic acid content of the four grape cultivars were significantly affected by the treatments. Tartaric and malic acids of ‘Red Globe’ were mostly influenced by the cluster-berry thinning treatment. ‘Alphonse Lavalleé’ accumulated the highest tartaric acid and malic acid in both the girdled/thinned and the cluster-berry thinned vines, respectively. The control and girdled ‘Trakya Ilkeren’ vines had the most tartaric acid. Control vines also contained high malic acid amount. ‘Buca Razakısı’, on the other hand, had the most prominent tartaric and malic acid levels in the girdled/thinned and thinned vines, respectively. Quality parameters also showed significant differences among the cultivars in response to the treatments.
Oceniono reakcję zawartości kwasów organicznych w czterech odmianach winogron przeznaczonych do bezpośredniego spożycia na zabiegi obrączkowania i przycinania w okresie dwóch okresów wegetacyjnych. Poza tym określono pH, kwasowość miareczkowaną, zawartość substancji rozpuszczalnych sałych oraz indeks dojrzałości. Analizy statystyczne pokazały, że na indywidualną zawartość kwasów organicznych czterech odmian wymienione zabiegi wpływały istotnie . Zabieg przycinania gron najbardziej wpłynął na zawartość kwasu winowego i kwasu jabłkowego odmiany ‘Red Globe’. Odmiana ‘Alphonse Lavalleé’ gromadziła najwięcej kwasu winowego i kwasu jabłkowego odpowiednio w winoroślach opaskowanych/przycinanych i w winoroślach z przycinanymi gronami. Winorośle ‘Trakya Ilkeren’ kontrolne i przycinane miały największą zawartość kwasu winowego. Winorośle kontrolne również zawierały dużą ilość kwasu octowego. Natomiast odmiana ‘Buca Razakısı’ miała najbardziej wyróżniającą się zawartość kwasu winowego i octowego odpowienio w opaskowanych/przycinanych oraz przycinanych winoroślach.

Opis:
Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes in plants, such as drought and heavy metal stresses. However, little is known about the roles of H2S in responses to chilling stress. In this paper, we demonstrated that chilling stress enhance the H2S levels, the H2S synthetase (L-/D-cysteine desulfhydrase, L/DCD) activities, and the expression of L/DCD gene in Vitis vinifera L. ‘F-242’. Furthermore, the seedlings were treated with sodium hydrosulfide (NaHS, a H2S donor) and hypotaurine (HT, a H2S scavenger) at 4°C to examine the effects of exogenous H2S on grape. The results revealed that the high activity of superoxide dismutase and enhanced expression of VvICE1 and VvCBF3 genes, but low level of superoxide anion radical, malondialdehyde content and cell membrane permeability were detected after addition of NaHS. In contrast, HT treatment displayed contrary effect under the chilling temperature. Taken together, these data suggested that H2S might be directly involved in the cold signal transduction pathway of grape.
