The events have also become elements that helped shape a tourism destination image or brand, through organized systems such as the portfolio model. However, the Covid pandemic, with its subsequent limitations and economic crisis, has severely impacted the events industry. No events, at any scale, were allowed to be organized, thus resulting in losses of billions of euros worldwide. With the economies slowly reopening, due to the partial lifting of Covid-related limitations, there seems to be room for the revival of tourism destinations. The analysis of previous studies has revealed a scientific gap, related to the possibility of reviving an urban destination through a large scale event. Therefore, the aim of the present scientific paper is to fill this gap, by looking into the perception of potential tourism demand on this subject. It also investigated the specifics of such an event, with a focus on the Romanian city of Sibiu. To this end a survey was conducted in the beginning of the year 2021, and its main results are presented in this article.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78371879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nopal Opuntia ficus-indica and related species are found in arid and semi-arid regions around the world. O. ficus-indica shows considerable variability in response to environmental conditions through variation of areola and spine attributes, among other traits. Therefore, the present study sought to morphologically identify some cactus pear plants in two areas of Algeria (Bejaia and Souk-Ahras) in order to evaluate the cactus pears by optimizing the extraction conditions of the phenolic compounds of the cladode, to evaluate the antioxidant activity of these compounds, to measure the total flavonoid content, and to compare the yields among three Opuntia spp. (O. ficus-indica, O. megacantha and O. amyclae) from the sites within the study regions. These three Opuntia spp. were subjected to extraction of polyphenols using a conventional method, and an ecofriendly process using ultrasound-assisted extraction (UAE) technique. Once the extractions was completed, the total phenolic content and flavonoids of the extracts were characterized. In addition, the antioxidant capacity of the total phenolic compounds (TPC) was determined. The UAE was better than conventional extraction for the recovery of TPC. The use of a solvent mixture (50% water/ethanol, v/v) improved the TPC extraction efficiency. These results show that UAE was a useful tool for the extraction of phytochemicals from cactus pear cladodes. Other factors and conditions that influence the optimization of TPC extraction should also be studied, such as pH, ultrasound frequency as well as ecological factors that could possibly influence extraction efficiency.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42170749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated activated charcoal's effect on the somatic embryogenesis of dragon fruit (Hylocereus species). Nine-month-old seed-derived dragon fruit stems wereplaced in basal Murashige and Skoog (MS) plates supplemented with 2, 4-D (1.5 mg/l) and activated charcoal (1g/l). Cultures were incubated in 14 h continuous light or under dark condition. MS medium without activated charcoal served as the control. Percent fungal contamination, degree of tissue browning, and callus growth (length, width, and total area) were assessed. A significant decrease in contamination was observed four days after inoculation (dai) in a medium containing activated charcoal regardless of the light condition used (p<0.05, T-test analysis). In contrast, no significant difference in fungal contamination between the two treatments was found eight days after incubation (dai). Fungal contaminants’ identities were done using a combined morphocultural and molecular analyses. The fungal isolates showed thick and white to grayish mycelia without spore production seven dai in potato dextrose agar medium. DNA sequence analysis showed a high percent similarity of the isolates to two Diaporthe species. Activated charcoal did not affect the length, width, and total area of the calli produced. However, a significant decrease in tissue browning was recorded (p<0.05). Overall results demonstrated the applicability of activated charcoal in dragon fruit tissue culture to reduce in-vitrobrowning. Additionally, examining further the possible role of fungal contaminants in dragon fruits would be valuable. A hedonic scale that can be used to assess tissue browning in dragon fruit is also described.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46017127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its pulp has an intense red color, sweet flavor, small and easily chewable seeds, and compounds with antioxidant capacity, such as betalains and phenolics, which confer the fruit an important nutraceutical value. Therefore, in selected markets, the price of pitaya is considered high. However, pitaya has big spines that cause consumer rejection, due to the possibility of puncture. The spines also make it difficult to handle pitaya and cause mechanical damages. These circumstances make it indispensable to remove the spines from the fruit, but collaterally, the shelf-life is decreased, and consequently, its commercialization in distant markets is more difficult. It has been reported that postharvest treatments, such as application of 1-methylcyclopropene (1-MCP) and chitosan (Ch) coatings added with hydrophobic components like oleic acid (OA), aid in preserving the quality of several horticultural products, but this effect has not been studied in pitaya. In the present study, the effects of 1-MCP (4.2 µL L-1) and/or a coating prepared with 9.1 g L-1 of Ch + 6.4 mL L-1 of OA (CO) were evaluated over the quality of pitayas, which were previously despined (D) during refrigeration (11 ± 1 °C; 93 ± 2 % relative humidity (RH)) for 15 d. The quality parameters studied were respiration pattern, ethylene production, weight loss, titratable acidity, skin firmness, and total soluble solids (TSS). It was found that the respiration rate and ethylene production corresponded to the climacteric type, independently of the treatment. The refrigeration conditions, minimized notoriously the weight loss of the fruits of practically all treatments. CO alone maintained the quality parameters and delayed the appearance of fungi, extending the shelf-life of despined pitayas up to 15 d. However, 1-MCP alone was not capable of preserving the evaluated quality parameters. The best treatment was D+CO+1-MCP, since it reduced notoriously the respiration and ethylene production rates, and inhibited loss of skin firmness, TSS, and acidity of the fruit. The results obtained herein are a progress in the limited knowledge of the postharvest physiology of pitaya fruit. More research is needed to deepen this knowledge and to optimize the postharvest handling of pitaya, in order to develop its market at global level for the benefit of producers and consumers.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46055408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central pivot irrigation was used to water prickly pear plantation with a density of 17,500 plants ha-1. To assess cladode quality (proximal analysis) before and after fermentation, a completely randomized bifactorial design was used -non-fermented (N-0) and fermented (N-F) cladodes- with three replicates each. To assess the fermented cladode effect in milk production, a completely randomized design was established with first-calving Holstein cows where each one represented one replicate. The treatments were two diets, Dnor (normal) and Dnop (fermented cladodes). The results showed sufficient bimonthly production (14,380.8±1,676 kg t ha-1) of fresh prickly pear leaves for daily bio-digestor functioning (200 kg).
