Resumo: | http://dx.doi.org/10.5902/1980509813324The management of ministumps to produce minicuttings results in the continuous removal of nutrients andit is necessary replacement to avoid depletion and decline in production. Thus, it is necessary to determinethe amount of nutrients removed over time, in different management models, to enable commercial mulproduction.The objective of this study was to evaluate two minigarden multiclonal systems of Toonaciliata, in plastic tubes and bed, for productivity and nutrients removal over time by ministumps, producedby seeds, submitted to successive collections of minicuttings. One hundred and eighty-six seedlings wereused in each management system. In this paper, it was determined the nutrient content in shoots issued by20 ministumps randomly selected in each system. Five shoots were collected at intervals of 32 days in bedsystem, while in the plastic tubes system three shoots were collected at intervals of 31 days. The data wereanalyzed by a sample simple random considering an infinite population of minicuttings. The qualitativetreatment average was compared by confidence interval using the Student t test, 5% probability, and thequantitative treatment (productivity and nutrients removed in time by ministumps) by regression. It hasbeen found that the productivity and nutrient contents removed by ministumps in bed were higher than inthe plastic tubes. Nitrogen and potassium are the nutrients most removed by ministumps in both systems.Here, it was presented the curves corresponding to the nutrients exported, to estimate the replacement thatwill be made in each system over time. |

Assim, é necessário determinar a quantidade de nutrientes removidos no tempo, em diferentes modelos de manejo, para viabilizar a produção comercial. O objetivo deste trabalho foi avaliar dois sistemas de minijardim multiclonal de Toona ciliata, conduzidos em tubete e canaletão, quanto à produtividade e remoção de nutrientes ao longo do tempo pelas minicepas, produzidas por via seminal, submetidas a coletas sucessivas de miniestacas. Foram utilizadas 186 mudas em cada sistema de manejo. Foram determinados os conteúdos de nutrientes nas brotações emitidas por 20 minicepas selecionadas ao acaso em cada sistema. Foram realizadas cinco coletas de brotações em intervalos médios de 32 dias no sistema canaletão, enquanto no sistema tubete foram realizadas três coletas de brotações em intervalos médios de 31 dias. Os dados foram analisados por amostragem simples ao acaso considerando uma população infinita de miniestacas. As médias dos tratamentos qualitativos foram comparadas por intervalo de confiança, utilizando o teste “t” de Student, a 5% de probabilidade, e os tratamentos quantitativos (produtividade e nutrientes removidos no tempo pelas minicepas) por regressão. Foi constatado que a produtividade e o conteúdo de nutrientes removidos pelas minicepas manejadas em canaletão foram superiores à dos tubetes. O nitrogênio e o potássio foram os nutrientes mais removidos pelas minicepas em ambos os sistemas de manejo. São apresentadas as equações que descrevem as quantidades removidas ao longo do tempo nos dois sistemas.Universidade Federal de Santa Maria2014-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1332410.5902/1980509813324Ciência Florestal; Vol. 24 No. 1 (2014); 71-77Ciência Florestal; v. 24 n. 1 (2014); 71-771980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/13324/pdf_1Souza, Juliana Sobreira deBarroso, Deborah GuerraSilva, Mírian Peixoto Soares daFerreira, Daniele de AlvarengaGravina, Geraldo de AmaralCarneiro, José Geraldo de Araújoinfo:eu-repo/semantics/openAccess2017-04-13T17:42:32Zoai:ojs.pkp.sfu.ca:article/13324Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T17:42:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
