However, Opuntia ficus-indica nutrient storage at plant and cladode levels and best fit plant requirements for fruiting remain practically unknown. Then, this research work aimed to identify the Boundary-Line Approach (B-LA) micronutrient optimum concentrations linked to maximum fruit yield per one-year old fructification cladode and sufficiency ranges at 90% maximum fruit yield for O. ficus-indica variety ‘Rojo Pelón’. Four years (2012 – 2015) data of fruit yield per cladode and micronutrient concentrations (B, Cu, Fe, Mn, and Zn) were used for the elaboration of scatter diagrams (n = 228) and selection of 7 to 10 points to estimate the B-LA quadratic functions. Then, the vertices allowed estimation of the optimum micronutrient concentrations: B = 33.62 mg kg–1, Cu =11.74 mg kg–1, Fe = 108.51 mg kg–1, Mn = 149.33 mg kg–1 and Zn = 414.91 mg kg–1 as linked to estimated maximum yield per cladode; and the sufficiency ranges at 90% maximum fruit yield: B = 24.44 to 46.25 mg kg–1, Cu = 8.68 – 15.87 mg kg–1, Fe = 73.73 – 143.3 mg kg–1, Mn = 114.89 – 183.77 mg kg–1 and Zn = 334.31 – 514.95 mg kg–1. The linked estimated maximum fruit yield per cladode varies from 1999.48 g to 2139.59 g. The proposed B-LA standards can be used to perform reliable micronutrient diagnosis and proper fertilization recommendations.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43704694","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}

Soil and water salinity are two of the main environmental factors that are considered primordial for the propagation, seedling growth, establishment, and development of coastal cacti. The objective of this study was to evaluate chirinola (Stenocereus eruca) seed germination and seedling fresh weight using NaCl as a saline medium. One hundred seeds divided into five replicates of 20 seeds in a completely randomized design, were treated with five salinity levels and distilled water as control (0, 2, 6, 8, and 10 dS m-1). Seeds were picked up from ripe fruits at a wild Stenocereus eruca population near San Carlos, Baja California Sur, México. Seedling fresh weight was significantly affected by saline stress, with lower fresh weight at the highest doses of 10 dS m-1, and the greatest fresh weight production was obtained with 0 and 2 dS m-1. However, germination percentage was greater at intermediate levels of 2 and 4 dS m-1 and lowest at 10 dS m-1 using NaCl; however, more studies should be conducted including other growth variables, seed viability, and salinity levels.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2021-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43058731","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}

A cutoff yield (1,166.67 g cladode-1) between the low- and high-yield subpopulations was determined after examining six cumulative variance ratio functions related to yield per 1-year old cladode.

In the present study, to optimize the biomass accumulation of Schlumbergera truncata under high pot density, we performed an experimental design that included different numbers of initials phylloclades and spraying or not with the synthetic cytokinin 6-benzylaminopurine (BAP). The highest biomass accumulation on a fresh weight basis and highest stem area expansion were recorded in pots with five initial phylloclades and BAP-sprayed plants. The decrease in individual biomass accumulation and the expansion of steam area were related to an increase in pot density. Since shading effect can be discard, responses to photo-assimilate uptake and distribution more associated with mechanical constraints on pot roots rather than with a competition between individual roots. Our results suggest that, when Schlumbergera truncata is grown in pots, the number of initial phylloclades may be higher than the usually recommended number per pot.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2021-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70745368","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 aim of the paper was to identify how the crisis caused by the COVID-19 pandemic negatively influenced the entrepreneurial intentions of young people. The study starts from the hypotheses that entrepreneurial intentions among young people have decreased due to the pandemic and that the existence of entrepreneurs in the family or circle of friends can positively influence young people. A review of the literature has created an overview of the \u0000importance of entrepreneurship in a country's economy and how the pandemic affected the entrepreneurs. To collect data, a questionnaire was distributed among young people between 16 and 35 years old. Following the evaluation of the respondents' answers, the two hypotheses were validated. It was found that young people who \u0000already have their own business also have relatives or friends who are entrepreneurs, who influenced them to follow the path of entrepreneurship. The pandemic has negatively affected young people, as before March 2020, 35.6% of young people wanted to start their own business, now 24.4% are undecided due to restrictions and \u0000uncertainty, and 1.6% gave up the idea setting up a business. Thus, we can conclude that the pandemic has caused disruptions to the economy and entrepreneurship, raising many challenges for current and future businesses.","PeriodicalId":54361,"journal":{"name":"Journal of the Professional Association for Cactus Development","volume":"24 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2021-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84014084","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}
