Growth regulators are used in agriculture to reduce vegetative growth, promote flowering and fruiting processes, and regulate production alternations. In this study, the effects of the use of paclobutrazol (PBZ) and different plant arrangements on the development and productive yield tomatoes grown for industrial use were evaluated. This experiment was carried out in the experimental area of the Universidade Estadual de Goiás, in a randomized block design with a 2×5 factorial arrangement (presence of PBZ and absence of PBZ in seedlings × planting spacing), with four replications and ten plants per plot. The paclobutrazol (growth regulator) applications were carried out in seedlings 15 days after emergence by applying 3.5 mL of the solution per tray at a concentration of 42.5 mg L-1 using a commercial product containing 25% of the active ingredient for the solution. The spacings were 0.15, 0.20, 0.25, 0.30, and 0.35 m between plants and 1.4 m between rows, corresponding to populations of 47,619; 35,714; 28,714; 23,809 and 20,408 plants/ha, respectively. The initial growth and development of the seedlings, characteristics related to productivity, and the physical and chemical quality of fruits harvested in each experiment were evaluated. It was observed that the application of paclobutrazol influenced the phylotechnical characteristics and technological quality of tomato fruits grown for industrial processing. The planting spacings between 0.21 and 0.27 m had better crop development and productivity.
O presente trabalho teve como objetivo estudar e avaliar a quantidade e qualidade das publicações científicas com Jatropha curcas abordando Biodiesel, Genética, Biotecnologia, Farmacologia, Pragas e Doenças. Para análise cienciométrica sobre Jatropha curcas foram obtidos dados no período entre 2015 e 2016 no laboratório de informática da Universidade Estadual de Goiás-Câmpus Ipameri/GO acessando a plataforma Thomson Reuters (ISI-Web of Science), avaliando-se os artigos com base na busca dos termos chave “Jatropha curcas” e “phisic nut’. O conjunto de artigos foi organizado conforme os temas: Biodiesel, Genética, Biotecnologia, Farmacologia, Pragas e Doenças, em seguida, catalogadas as seguintes informações: Tema, título, número de autores, país de desenvolvimento, nome do periódico e fator de impacto (Journal Citations Reports-JCR). As pesquisas com Jatropha curcas são voltadas principalmente para produção de biodiesel em função do elevado teor de óleo nas sementes desta espécie. A literatura é escassa de informações a respeito dos estresses bióticos (pragas e doenças) para a cultura do pinhão manso. Os países que mais publicam trabalhos científicos com Jatropha curcas nos temas de biodiesel, genética, biotecnologia, farmacologia, pragas e doenças são Índia, China, Brasil, Malásia e Tailândia. A maior parte dos trabalhos apresentam baixo fator de impacto (JCR) e disponibilizados principalmente em língua inglesa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
