To determine the influence of fruit ripening, and seed extraction from the fruit on seed germination of a Venezuelan type of Capsicum chinense, a factorial experiment with 10 replications was conducted. Influence of the six combinations between three fruit maturation levels (green fruits, early-ripe fruits, and totally-ripe fruits) and two seed extraction moments of seed from the fruits (at the same day of the harvest and seven days after the harvest) were evaluated on seed germination percentage and days number to germination. Each replication consisted of 100 seeds, and seed germination was recorded for ten days. Results displayed no interaction between fruit ripening and extraction of seed for both dependent variables, but significant differences (P<0,01) were recorded for germination percentage among fruit ripening levels (the same for totally yellow and fruits changing color, but higher than green fruits), and between separation moment of seed from the fruits (seven days after the harvest resulted in 80% more germination rate as compared to seed separated at the same day of the harvest). Significant differences (P<0,01) were recorded also for the number of days to germination: seeds extracted from early- and totally-ripe fruits did not have significant differences (P>0,05) and germinated in 7,30 days in average, but they germinated faster (P<0,01) than seeds coming from green fruits which germinated in 8,40 days in average; seeds extracted from fruit 7 days after harvest germinated in 6,50 days in average, faster (P<0,01) than seeds extracted from the fruit the same day of harvest (8,75 days in average). Seeds of this type of sweet pepper germinate more abundantly and faster when they are separated from ripening fruits seven days after harvest.","PeriodicalId":56220,"journal":{"name":"Biotecnologia en el Sector Agropecuario y Agroindustrial","volume":"135 1","pages":"45-63"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67758720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Se evaluaron dos protocolos para la inoculación del CMV en plantas indicadoras (Nicotiana benthamiana y N. tabacum cv. Xanthi) y diferentes métodos de detección de este virus. La infección de plantas con CMV se logró mediante transmisión mecánica e infiltración. La presencia del virus se confirmó mediante la expresión de síntomas, serología (ImmunoStrip®), RT-PCR y por secuenciación. Los resultados confirmaron la efectividad del método de transmisión mecánica, en el cual, las plantas infectadas presentaron sintomatología asociada con el virus 15 días después de su inoculación. La prueba serológica permitió detectar la presencia del patógeno solo en las plantas de N. benthamiana, mientras que la prueba de RT-PCR en todas las plantas evaluadas. Los resultados de secuenciación mostraron altos valores de identidad nucleotídica con las secuencias reportadas en el NCBI para este virus.

This study seeks to combine complementarily and integrally the bibliometry with the technological outlook to obtain an image of the current state of biotechnology in a specific area. This contributes with a trend-setting in a socially relevant sector that currently addresses global challenges such as climate change and energy and food security. Through a bibliometric study, it determines the dynamics of the scientific production, key authors, country participation and language trends in the domain of Biotechnology in the agricultural and agro-industrial sectors. In addition, a technological outlook is presented, in which, based on the analysis of trends in patents, the innovative state of the area is established. The main result is associated with the dynamics of scientific production, which according to the Lotka law; states that the percentage of authors who produce N articles is inversely proportional to a power of N. The technological outlook is consistent with the Latin American studies, concluding that, despite of the increasing dynamics, there is a poor development of technology in the sector.","PeriodicalId":56220,"journal":{"name":"Biotecnologia en el Sector Agropecuario y Agroindustrial","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47869464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lignocellulosic material was dried at 80°C for 24 h to remove moisture; then crushed and sieved with meshes of different particle sizes; characterized by elemental analysis to check for the presence of cellulose, hemicellulose, and lignin, as well as by Fourier Transform Infrared Spectrometry to verify the existence of functional groups responsible for the adsorption process. It was found that the best particle size was 1 mm, with a removal percentage of 73,4 and 79,3% for Cr (VI) and Hg (II), respectively. When establishing the adsorption kinetics, it was verified that the elimination percentage increases with time up to 5,5 h of contact with the Hg (II) solution and 3,8 h with the Cr (VI) solution.","PeriodicalId":56220,"journal":{"name":"Biotecnologia en el Sector Agropecuario y Agroindustrial","volume":"19 1","pages":"54-65"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47628771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
