Educational tourism is a new branch of tourism, which has experienced a significant increase in recent times, due to the important benefits it brings to the local communities. Universities and other educational specialized institutions may highly contribute, support and encourage local development through educational tourism. Students who benefit from studying abroad can be considered as symbolic educational tourists, and their stay is considered to have a high potential to generate benefits. The host university may facilitate the development of better relationships between tourists and local communities in order to contribute to the development of the local economy in a sustainable and resilient way. Education tourism has to be taken into account by all educational institutions due to the different learning opportunities that might be better exploited. This paper focuses on some indicators considered to be relevant for educational tourism.

The physical and chemical parameters of the soils are decisive in the physiological development of plants of agricultural interest. In the case of some species of Opuntia called xoconostle, the impact of the physical and chemical quality of the fruits, on the soils where they are grown, is unknown. The objective of this study was to determine the physical-chemical quality of two xoconostles fruits (Opuntia matudae cv. Cuaresmero and O. joconostle cv. Burro) cultivated and wild in the Valle del Mezquital, Hidalgo, Mexico. The physical and chemical characteristics of soils and fruits of xoconostle O. matudae and O. joconostle cultivated and wild in the state of Hidalgo, Mexico were analyzed with five repetitions. The data were treated with the JMP V8 program, expressed as mean ± standard deviation. The differences among the means of the fruits were treated with analysis of variance (ANOVA) with a significance level of P?0.001. The differences among the means were evaluated with the Tukey test with a significance level of (P?0.05). Among the physical and chemical properties of the soils, they presented a pale brown (10YR 6/3), with higher porosity, more acidic pH, and exchangeable ions, where wild xoconostle plants (O. joconostle cv. Burro) grow and develop, the fruits presented increases in the quality parameters in weight of whole fruit and pulp, longitudinal and equatorial diameter, °Brix, pH, ash, fiber, protein, K+, Na+, Ca2+ y Mg2+ .The xoconostle fruits of wild plants of Chapantongo O. joconostle showed statistically significant differences between sites and quality parameters concerning to O. matudae cv. Cuaresmero. Xoconostle fruits can be considered in the diet as a nutraceutical food alternative. It can also be used as a natural ingredient in food, food products, and by-products.

Forage cactus species exhibit distinct morphological characteristics, which have a relationship to yield and can be affected by different water conditions. The objective was to analyze, with the principal components analysis (PCA), the association between morphological and productivity variables in forage cactus clones in different water regimes. We cultivated, in Serra Talhada, Brazilian semiarid, the Miúda (MIU), Orelha de Elefante Mexicana (OEM) and IPA Sertânia (IPA) clones under four water regimes based on crop evapotranspiration – ETc (0%, 40%, 80% and 120% ETc). Between the years 2016 and 2018, morphological and crop productivity data were obtained. Two main components explained >82% of the total variability of the data, and the relationship between morphological and production variables depended on the clone and the water regime. The production of fresh and dry matter was more influenced by the morphological characteristics in the MIU and OEM clones. The IPA clone showed no correlation between the variables analyzed, regardless of the water regime. PCA can be used to understand the growth dynamics of plants and to identify the water conditions that act in the production of cactus clones, favoring better management in the cultivation of culture.
牧草仙人掌具有明显的形态特征，与产量有关，并受不同水分条件的影响。采用主成分分析法（PCA）分析了不同水分条件下饲草仙人掌无性系的形态和生产力变量之间的关系。我们在巴西半干旱地区Serra Talhada种植了Miúda（MIU）、Orelha de Elefante Mexicana（OEM）和IPA Sertânia（IPA）无性系，其水分状况基于作物蒸发蒸腾量（0%、40%、80%和120%ETc）。2016年至2018年间，获得了形态和作物生产力数据。两个主要成分解释了数据总变异性的>82%，形态和生产变量之间的关系取决于克隆和水情。新鲜和干物质的生产更多地受到MIU和OEM克隆的形态特征的影响。IPA克隆在所分析的变量之间没有显示出相关性，而与水分状况无关。PCA可用于了解植物的生长动态，并确定仙人掌无性系生产中的水分条件，有利于在培养中进行更好的管理。

The objective was to evaluate the fermentation process, nutritional quality, and aerobic stability of mixed silages of arboreal cotton and cactus pear. This was a completely randomized design, with five levels of inclusion of cactus pear (0, 15, 30, 45, and 60%) in the arboreal cotton silage and four replications per treatment, totaling 20 experimental units. Data were submitted to analysis of variance and regression at a 5% probability level for type I error. The inclusion of cactus pear resulted in increased losses from gases (P<0.001), effluents (P<0.001), buffering capacity (P<0.001), aerobic stability (P = 0.010), and pH upward trend (P<0.001). There was a decreasing linear effect on dry matter recovery (P<0.001), pH (P<0.001), ammonia nitrogen (P <0.001), the maximum difference in the temperature of the silage in relation to the environment (P = 0.005) and maximum pH (P<0.001) of silages. The inclusion of cactus pear affected the maximum temperature (P<0.001) of silages in a quadratic way. There was a decreasing linear effect of dry matter (P<0.001), ether extract (P<0.001), Organic matter (P<0,001), crude protein (P = 0,002) and neutral detergent fiber corrected for ash and protein (P = 0.030). The use of cactus pear promoted an increasing linear effect for the levels of mineral matter (MM) (P<0.001), corresponding to an increase of 0,271%, for each 1% inclusion of cactus pear. The increase in the proportions of cactus pear in the silages promoted an increasing linear effect for mineral matter (P<0,001). The inclusion of cactus pear by up to 60% in arboreal cotton silages alters the fermentation profile with increased fermentation losses and nutritional reduction. However, it still presents characteristics of good quality silages.

The study includes the analysis of cultural, commercial, and safety factors that affect the potential of the trade of the red sour pitaya (Stenocereus gummosus), as well as its characterization, consumer patterns, consumption channels, and the relevance, identity, and cultural value of the fruit in the Municipality of La Paz, Baja California Sur, Mexico. The investigation has the objective of understanding the perception of the product in local knowledge, which is identified in the study area, where the wild fruit takes an added value in informal commercialization and is amalgamated with the local culture. For the analysis and data collection, a simple random sampling was conducted, on 227 economically active people with purchasing power. The method of applying the instrument was digital, limiting face-to-face contact with people due to the current Covid 19 pandemic. The exercise characterizes a population with mostly university studies, which consumes the product in a traditional way, which reflected a greater appreciation of the pitaya fruit, by older people.

Nopal (Opuntia ficus-indica (L.) Mill.) cladode has garnered great interest recently in the area of agro-energy as emerging biomass due to its sustainable production. The objective of this study was to compare the biochemical methane potential of different nopal cultivars in co-digestion with cow manure. For this purpose, two different nopal cladodes: cow manure proportions (75:25 and 82:18) and three different cultivars (Atlixco, Copena V1, and Milpa Alta) were evaluated. The results indicated that the treatments with higher biochemical methane potential (mL CH4 g-1 VSfed) were Milpa Alta 75:25 (71.4), Copena V1 75:25 (66.5), Milpa Alta 82:18 (64.6), and Copena V1 82:18 (59.0), which showed no statistical difference (P>0.05) between them, whereas the Atlixco treatments (75:25 and 82:18) had the lowest (P<0.05) values (52.8 and 41.5, respectively). The results suggest that the cow manure proportion and nopal cultivar used in a co-digestion system may influence its biochemical methane potential.
无花果(Opuntia ficus-indica)由于其可持续性生产，最近在农业能源领域引起了人们的极大兴趣。本研究的目的是比较不同品种野菜与牛粪共消化的生化甲烷势。为此，对两种不同品种(牛粪比例分别为75:25和82:18)和3个不同品种(Atlixco、Copena V1和Milpa Alta)进行了评价。结果表明:生化甲烷势(mL CH4 g-1 VSfed)较高的处理为Milpa Alta 75:25(71.4)、Copena V1 75:25(66.5)、Milpa Alta 82:18(64.6)和Copena V1 82:18(59.0)，差异无统计学意义(P<0.05)，而Atlixco处理(75:25和82:18)的生化甲烷势最低(分别为52.8和41.5)。结果表明，牛粪比例和共消化系统中使用的nopal品种可能影响其生化甲烷势。

Opuntia species from arid and semiarid environments have dormant seeds. The objective of this study was to evaluate how the soil influences seed germination of the cactus O. dejecta. We hypothesized that O. dejecta seeds in the basaltic rocky soil will show lower seed germination than seeds in a site with alluvial soil from the coastal plain. An experiment of partial reciprocal transplant was performed, placing seeds from basaltic soil (San Ignacio population) in pots containing alluvial soil from Puente Nacional population and in slabs from basaltic soil, and placing them on two greenhouses, in San Ignacio population and Puente Nacional population. We found that seed germination (%) was lower in San Ignacio site (with basaltic soil) than in Puente Nacional site (with alluvial soil), and that alluvial soil showed higher seed germination than basaltic soil, as well as higher seed germination in Puente Nacional than in San Ignacio. The results suggest that seed dormancy for the population situated in the rocky condition is a trait locally adapted, and the basaltic soil can be considered as a selection factor.

Ariocarpus retusus is an endemic species of Mexico subject to special protection by the Mexican government due to its vulnerability to habitat disturbance. Previous studies have reported secondary metabolites in A. retusus with interesting biological activity. However, the use of these secondary metabolites has limitations. The aim of this study was to establish protocols for obtaining friable callus and cell suspension cultures that allow the subsequent development of strategies for obtaining secondary metabolites. Seedlings were obtained from seeds which were exposed to different concentrations of auxins and cytokinins to induce callogenesis. The callus generated was subcultured in Murashige and Skoog (MS) medium with modifications in the content of ammonium nitrate and potassium nitrate, and incubated in different photoperiod conditions (16:8 h light: dark and continuous darkness). Likewise, cell suspensions were established and characterized by friable callus. The MS medium supplemented with 2 mg/L 2,4-D, 2 mg/L BAP, and 3 mg/L KIN allowed the development of vigorous callus. Callus friability was enhanced by decreasing ammonium nitrate (410 mg/L) and increasing potassium nitrate (2850 mg/L). The absence of light during incubation induced friable callus. The addition of myo-inositol (3 mg/L) significantly (p = 0.000) influenced the increase in biomass of cell suspensions.

The addition of myo-inositol (3 mg/L) significantly (p = 0.000) influenced the increase in biomass of cell suspensions.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43377318","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 first nutritional profiling of all Trichocereus species of columnar cacti from northern Argentina is reported. Commonly called ‘cardones’ by locals, they are iconic elements of the flora and cultural heritage in the region. A general chemical characterization of the four species (T. atacamensis, T. terschekii, T. tarijensis and T.schikendatzii) was performed. Stem tissues for each species in terms of humidity, ash, protein content, carbohydrates, and reducing sugars, as well as phenols and anti-radical activity were profiled. The results constitute an advance in terms of general knowledge of these vulnerable and exploited Andean cacti and will contribute to ponder the most appropriate method of conservation and the possibility of bioprospecting and regulating its sustainable use.
首次报道了阿根廷北部所有柱状仙人掌的毛状属物种的营养特征。它们通常被当地人称为“卡多尼”，是该地区植物群和文化遗产的标志性元素。对四种蜱(atacamensis, T. terschekii, T. tarijensis和T.schikendatzii)进行了一般化学表征。在湿度、灰分、蛋白质含量、碳水化合物和还原糖以及酚类物质和抗自由基活性方面，对每个物种的茎组织进行了分析。这些研究结果是对这些脆弱和被开发的安第斯仙人掌的一般认识的进步，将有助于思考最适当的保护方法，以及生物勘探和调节其可持续利用的可能性。

Information and Communication Technology — ICT (i.e., computers and laptops, tablets, mobile phones, smartphones, software, audio-visual systems, wireless, VOIP, GIS, GPS, mobile app, analytical tools, augmented reality systems, holograms, virtual reality technologies) and ˗ mainly ˗ online information sources (multiplatform web pages, search engines, social media platforms) have changed how distribution, selling and consumption processes work. This also involved a revolution in how travel-related information is searched. Digital technologies have brought significant transformations to the tourism industry, significantly changing tourism business, products and destinations. The increase of digital platforms stimulated the variety and volume of tourism products, services and experiences. Nowadays, digital technologies are used as marketing tools by tourism companies, in order to boost efficiency and increase communication and awareness among visitors. The expansion of the Internet has supported the productivity of tourism-related applications and generated an opportunity for businesses to expand and attract more customers. Digitalization has changed the way tourist services are provided because customer expectations converge towards more digital solutions and tools. The present paper aims to investigate the online communication channels used by tourism organizations to promote businesses, products and services. The research was conducted in Timiș County, Romania, as a pilot study. The findings of the present paper provide valuable information regarding the limitation of digital marketing tools used by tourism companies and how to capitalize them as a strategic tool.
