The chemical properties (total lipids, proteins, total sugars, moisture, and dry matter) of the peel and seeds were determined and the morphological characteristics (whole fruit weight, pulp weight, peel weight, and the number and weight of fertilized and aborted seeds) of the fruits and their seeds from both cultivars were compared. Surface-sterilized seeds were separated into six groups according to their length and germinated on Murashige and Skoog basal culture medium. Seed viability, by analyzing the correlation between (1) germination rate and seed length, and (2) germination rate and seed weight was determined. Results showed that the province or cultivar factor had significant effects on the morphological characteristics of fruits and seeds. Fruit and pulp weights were positively correlated with the seed number. In addition, a marked difference in the sugar content of the peel was observed (57.29% in the ‘‘Dellahia’’ cultivar compared to 36.66% in the “Hajria” cultivar). The seeds of the “Dellahia” cultivar contained 10.41% fat and 8.12% protein, whereas the seeds of “Hajria” contained 12.27% fat and 8.67% protein. Seed viability was assured from a length of 3.5 mm in both cultivars. The seed germination rate correlated positively with increased length and weight; however, this rate was significantly different between the two cultivars.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42473633","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 research records the sociocultural and economic importance of the harvest of pitaya sahuira (Stenocereus montanus) in two localities of the state of Sinaloa, Mexico: 1) San José del Llano, Badiraguato, and 2) several small communities in the municipality of Choix. Semi-structured surveys and participatory evaluation were carried out with different people who harvest and market the pitaya fruits during the production season to document the harvest method, productivity, commercial value, fruit destination, cultural perceptions, and the differences between both regions. In both localities, daily harvests are made, and it constitutes the main economic activity during the production season, about 40 to 50 days between May and July. In San José, the harvest is carried out by men and women, while in Choix, it is practically exclusive by men. Higher productivity was recorded in San José, reflected by a greater amount of daily fruit harvested in a workday; however, in Choix, the fruit has a higher sales value, which balances the estimated annual earnings of around 1,940 dollars per harvester (~40,000.00 Mexican pesos). Given its great commercial value, it is necessary to implement cultivation and domestication strategies at the local level, as a regional economic alternative and to reduce the pressure on native populations. This work incorporates additional evidence on the great cultural and economic importance of the genus Stenocereus in Mexico and motivates the design of better strategies for sustainable use and the revaluation of this biocultural heritage.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48562093","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 evaluated the effect of different soil moisture contents on the growth, production, and gel quality of aloe grown in an arid region of Mexico. The study was conducted in a randomized complete block design with three replicates. Base on the percentage of field capacity (FC), three irrigation treatments were tested: 42%, 72%, and 100% of FC corresponding, on average (± standard deviation), to 0.12 ± 0.02 m3 m-3 (as control), 0.18 ± 0.02 m3 m-3, and 0.24 ± 0.02 m3 m-3 of soil water content, respectively. Aloe plants watered with 72% of FC had greater plant height and leaf width than plants watered at 42% of field capacity, while plants with 100% of FC treatment had the longest (56.1 cm) and thickest (1.5 cm) leaves. Aloe plants irrigated at either 72% or 100% of field capacity produced the freshest leaf biomass and gel. In contrast, plants grown at 42% of field capacity treatments had the highest pH (4.94), total soluble solids (1.77 °Brix), ash content (0.62%), methanol-precipitated solids (1.24%), and total solids (1.88%) of aloe gel. Even though the lowest soil moisture content (42% of field capacity) reduced plant and leaf growth and leaf and gel yields, gel quality was enhanced, meeting the gel quality standards demanded by the international market.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47495557","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}

Therefore, this research characterized regularities of the scientific production and identified emerging research trends on D. opuntiae, using one-dimensional and multidimensional bibliometric indicators. The search and retrieve of metadata from nine scientific publications databases (Biological Abstracts, Cab abstracts, Crossref, Google Academic, Dimensions, Microsoft Academic Search, Science Citation Index Expanded, Scopus, and Zoological Record) was condensed into a 193 documents collection, spanning from 1848 to 2021 using the Zotero® bibliographic reference manager. Publish or Perish® and Excel® were used to generate one-dimensional indicators and VOSviewer® for multi-dimensional indicators. Eighty percent of the publications on D. opuntiae were registered in the last 20 years, which denotes the specie´s recently acquired importance. The addressed topics in the two assessed periods showed drastic changes, since, while in the first period (1848-2000) these were directed, particularly, to its applications as a biological control agent for various Opuntia species; during the next period (2001-2021), they focused on generating strategies for its eradication and control. A high number of non-peer-reviewed publications were not included in our studies, such as serials, books, theses, and conference proceedings. Despite the recent interest in D. opuntiae and the growing number of scientific documents, no previous publications were found that address this issue. Finally, the research allowed for the identification of emerging research trends and showed their locations and who makes up the clusters or research groups, and the addressed topics, which could facilitate collaboration networks establishment and contribute to the scientific development of D. opuntiae.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43361987","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}

More broadly, the virus has transformed our\u0000everyday lifestyles, inter-human interactions, dynamics of life and last but not least, perceptions upon travelling.\u0000The tourism sector has been tremendously affected by the expansion of the virus, with hundreds of countries closing\u0000borders, introduction of numerous travel restrictions and suspended flights.
