A través de la técnica de semillas sintéticas (SS), el CTV posibilita la propagación y conservación ex situ de recursos fitogenéticos. El monte negro (Bougainvillea spinosa (Cav.) Heimerl.), es una especie del monte, nativa de Argentina. Se evaluó la propagación de B. spinosa a través del CTV, para contribuir a su conservación y uso sustentable. Se estudió la germinación in vitro de las semillas, la expresión morfogénica de explantes juveniles y el almacenamiento de SS de esta especie. Se alcanzó una germinación de 98,67% y los parámetros germinativos evaluados fueron comparables a los de otras especies (Energía germinativa:61,33%; tiempo medio de germinación:1,79 días; índice de vigor:76,80). La formación de callo fue la respuesta morfogénica más frecuente, aún en medios libres de reguladores de crecimiento y sólo se logró un 10% de enraizamiento en medios suplementado con IBA 5mg/l. Por otra parte, se logró la conversión de las SS luego del almacenamiento en frío (13,33%).

These compounds have nutritional and therapeutic properties such as neuroprotective, antioxidant, anti-inflammatory, anticoagulant, hyperlipidemic, immunomodulatory, and immunoregulatory. For this reason, phototrophic organisms are an essential supply for different industries since they can satisfy their current commercial demand while reducing the environmental impact and promoting the bioeconomic development of the country. However, research on these microorganisms is still limited and focused on a limited group of species. This review examines the biotechnological applications of bioactive metabolites produced by several photoautotrophic microbial species from poorly explored environments and their industrial application. As a result, we could determine that there are many little-explored species with a wide variety of bioactive compounds. Moreover, they have potential uses in various industries such as nutraceuticals, cosmeceuticals, and energy. Furthermore, it was concluded that the bioindustry represents a business opportunity and can also be established as a platform for modernization and competitiveness for various country's economic sectors.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41387178","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 objective was to evaluate the biochemical response of two basil varieties inoculated with AMF Rhizophagus fasciculatus and appraise its usefulness as a NaCl-stress mitigator. A completely randomized design with a factorial arrangement, four replicates per treatment and four plants per replicate was used. Three factors were considered, (1) two basil varieties (Napoletano and Nufar); (2) three NaCl concentrations (0, 50 and 100 mM); and (3) R. fasciculatus inoculum absence or presence (0 and 10 g). The variables evaluated were a substrate chemical analysis; shoot (STP) and root (RTP) total protein content; shoot (SP) and root (RP) proline content; shoot (SGA) and root (RGA) glutathione peroxidase activity; spore count and colonization. The spore content was 50 to 70 spores per gram of inoculum. The STP and RTP were highest in both varieties in 0 mM with AMF and decreased in Napoletano in 100 mM. The SP and RP were highest in Nufar in 50 and 100 mM with AMF and lowest in Napoletano in 0 and 50 with AMF. The SGA and RGA were highest in Napoletano in 50 and 100 mM with AMF.

In Venezuela, fungi and red squirrels mainly affect its productivity. The objective was to evaluate the influence of the cocoa crop structure on the level of damage caused by red squirrels on the pods. The vegetation structure was defined in 15 farms assessing the cocoa tree biomass, the magnitude of shade tree cover, number of associated crops, presence of alternative fruit trees, and the type of ecological succession present in the surrounding. The % of damage was calculated, and nonparametric tests were used to process data. The damage was higher in crops with less shade cover, a more abundant number of associated crops, and alternative fruit trees. Squirrels used the cocoa pods opportunistically but preferred other fruits. It is concluded that pods can be a complementary food for squirrels to the extent that the cocoa plantation is more complex and has a connection with the forest. Shade cover did not directly influenced squirrels, but it is crucial for bird predators which are more sensitive to disturbance.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":"28 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80030005","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 objective of the research was to characterize the productive system of Sacha Inchi in the municipality of Arauquita, Colombia. Fifty farmers were selected (40 peasants and 10 ex-combatants of the FARC-EP), using an intentional non-probabilistic sampling. The information was collected through a questionnaire and two participatory workshops aimed at identifying limitations and potentialities of the agroecological and productive system. Data were analyzed using descriptive and multivariate statistics. The classification analysis allowed partitioning the set of farmers, based on socioeconomic and environmental characteristics necessary to guide extension plans. The results showed that the most used agroecological practices are: soil conservation, application of lime, use of compost as fertilizer, use of certified seed and direct sowing. Low crop rotation and limited use of phytosanitary products were evidenced. The participatory workshops made it possible to identify crop limitations such as low productivity, few marketing channels and lack of knowledge of some agroecological techniques necessary to improve its productivity. Agroecological practices must be reinforced and expanded through extension programs to achieve recognition as agroecological producers, since this crop is a highly viable alternative for the municipality of Arauquita, within the framework of the peace agreement.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":"69 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87650185","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}
