Red Grape

Red grape (Vitis vinifera L.) is easy to get perishable and wrinkles/wilt, brown in color, and soft fruit flesh. one of the benefits of edible coating is that it can protect products from microbiological damage. The ability of aloe vera as an antimicrobial can be a potential ingredient for making edible coatings,. Besides, the use of aloe vera as an edible coating is also very easy and affordable (cheap). The purposes of this study are to determine the effect of glycerol addition and the best treatment of aloe vera edible coating on the quality of the red grape. The experiment used a completely randomized design (CRD) as an experimental design with 4 treatment factors, namely the concentration of glycerol (P1=0%, P2=3%, P3=5%, P4=7%). Each concentration was repeated three times. The parameters observed were physicochemical characteristics (weight reduction, pH, total titrated acid), hedonic quality test (color, aroma, texture). The results showed that the treatment of 3% glycerol was the best treatment since it could maintain the condition of the fruit well during storage, especially weight reduction, aromas, and textures. Parameters that highly affect the quality of red grapes are texture and weight loss.

Quality Aspects

The Isabel grape (Vitis labrusca × Vitis vinifera L.) is the most produced grape in Brazil, however, it has a short postharvest period due to rapid degradation during storage. The use of coating has been an alternative to prolong the shelf-life of fruits. The objective of this work was to evaluate the postharvest quality of 'Isabel' grapes coated with tamarind (Tamarindus indica L.) seed starch. The experimental design was completely randomized with five treatments with edible coating based on tamarind seed starch, at concentrations of 0, 0.5, 1, 1.5 and 2% and five replications. The grapes were immersed in the solutions with different concentrations and stored in B.O.D. at 12 ± 2 ° C and 85 ± 5% relative humidity for 12 days. Weight loss, color, pH, soluble solids, total titratable acidity, relationship between soluble solids and acidity, anthocyanins, flavonoids and vitamin C were evaluated. The 2% coating of tamarind seed starch was the most efficient, providing shelf life in 12-day grapes when stored at 12 ± 2 ° C and 85 ± 5% RH, and maintaining the main quality aspects, with higher SS / TA ratio and vitamin C.

Red Grape

The in vitro cell cultures derived from the grapevine (Vitis vinifera L.) have been used for the production of stilbenes treated with different biotic and abiotic elicitors. The red-grape cultivar Váh has been elicited by natural cellulose from Trichoderma viride, the cell wall homogenate from Fusarium oxysporum and synthetic jasmonates. The sodium-orthovanadate, known as an inhibitor of hypersensitive necrotic response in treated plant cells able to enhance production and release of secondary metabolite into the cultivation medium, was used as an abiotic elicitor. Growth of cells and the content of phenolic compounds trans-resveratrol, trans-piceid, δ-viniferin, and ɛ-viniferin, were analyzed in grapevine cells treated by individual elicitors. The highest accumulation of analyzed individual stilbenes, except of trans-piceid has been observed after treatment with the cell wall homogenate from F. oxysporum. Maximum production of trans-resveratrol, δ- and ɛ-viniferins was triggered by treatment with cellulase from T. viride. The accumulation of trans-piceid in cell cultures elicited by this cellulase revealed exactly the opposite effect, with almost three times higher production of trans-resveratrol than that of trans-piceid. This study suggested that both used fungal elicitors can enhance production more effectively than commonly used jasmonates.

The 19Th Century

The direction related with production of vine planting material originated from the 19th century, after the advent of Phylloxera vastatrix F. in which a large part of the vineyards in Bulgaria and the main wine-growing countries were destroyed. Only solution was proposed for grafting vine varieties from Vitis vinifera L. on resistant rootstocks. A number of biological characteristics of the vine influence both the nursery for scions and the rootstock nursery. One of them, which is main is the affinity of different rootstocks on the different vine varieties. In the southern Bulgaria, where the Mavrud variety is characteristic, high losses are observed due to the low yield of first-class vines. In Bulgaria, the Mavrud variety is highly valued due to its biological qualities, resulting in extracts and dense red wines that have glorified our country.

The purpose of this study was to evaluate the environmental quality of polluted areas near the Baia Mare Mining and Smelting Complex for future improvements the quality of the environment in polluted areas, such as the city of Baia Mare and its surroundings. Samples of soil and organs of grapevine (Vitis vinifera L.) were collected from Baia Mare, Baia Sprie and surrounding areas (Simleul Silvaniei) and their content of Cu, Zn, Pb, Cd, Ni, Co, As, Cr, Hg were analyzed. Most soil and plant samples showed higher metal concentrations in Baia Mare and Baia Sprie areas compared to Simleul Silvaniei, exceeding the normal values. The results obtained from the translocation factors, mobility ratio, as well as from Pearson correlation study confirmed that very useful information is recorded in plant organs: root, canes, leaves and fruit. Results also indicated that Vitis vinifera L. has some highly effective strategies to tolerate heavy metal-induced stress, may also be useful as a vegetation protection barrier from considerable atmospheric pollution. At the same time, berries are safe for consumption to a large degree, which is a great advantage of this species.
