Resumo: http://dx.doi.org/10.5902/198050985749Bamboo is a monocotyledon of tropical origin which grows fast and is considered an important environment regenerator because of its root system. Dendrocalamus giganteus is popular learned by giant bamboo, being a big bush species, its culms can be from 24 to 40 meters high, with diameters from 10 and 20 centimeters. This work had the objective of a chemical analysis from giant bamboo to aim at giving information from its chemical composition from 2 to 6 years of age. Bamboo culms were collected in the Agriculture Experimental area of the Mechanical Engineering Department of UNESP – Bauru, where it is carried out the systematic handling from different bamboo species to this plant research and divulgation. Samples from base were collected from 2 and 6 years in the same bush, in total of 5 samples, with 2 high meters each, cropped in March, half moon. Chemical analysis was done with internodes using TAPPI Methods. The average percentage extractives from hot water, cool water, total extractives and ash content were not related to the age. The major percentage of hot water extractives, with values of 12.04%, cold water extractives, with 10.25%, and total extractives, with 12.91%, was observed by the age of two years. The major ash content was obtained on three years, with value of 1.09%.  The mean value of NaOH extractives decreased from 25.72%, in two years, to 20.17% at six years old. The same behavior was observed for ethanol toluene extractives, decreasing from 10.91% to 4.61%.  The mean lignin content was not influenced by age, varying from 22.66 to 24.11%.

O Dendrocalamus giganteus é popularmente conhecido por bambu-gigante, sendo uma espécie entouceirante de grande porte, cujos colmos podem variar de 24 a 40 metros de altura, com diâmetros entre 10 e 20 cm. Esse trabalho teve como objetivo analisar quimicamente os colmos do bambu-gigante visando fornecer informações sobre a sua composição química nas idades de 2 a 6 anos. Os colmos do bambu foram coletados na área Experimental Agrícola do Departamento de Engenharia Mecânica da UNESP-Bauru, onde é realizado o manejo sistemático de diversas espécies de bambu para fins de pesquisas e divulgação dessa planta. Foram retiradas amostras da base entre bambus com idade de 2 a 6 anos de uma mesma touceira, totalizando 5 amostras, com 2 metros de altura cada, colhidas na lua minguante no mês de março. As análises químicas foram feitas com os entrenós, utilizando as normas e procedimentos da TAPPI. A porcentagem média de extrativos em água quente, extrativos em água fria, extrativos totais e teor de cinzas não apresentaram relação direta com a idade. A maior porcentagem de extrativos em água quente, com valor de 12,04%, extrativos em água fria, com 10,25%, e extrativos totais, com 12,91%, foi observada aos 2 anos de idade. A maior porcentagem de cinzas foi obtida aos três anos, com valores de 1,09%. O teor médio de extrativos em NaOH diminui de 25,72% aos dois anos para 20,17% aos seis anos de idade. O mesmo comportamento foi observado para os extrativos em etanol tolueno, diminuindo de 10,91% para 4,61%. O teor médio de lignina não sofreu influência da idade, variando de 22,66 a 24,11%.Universidade Federal de Santa Maria2012-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/574910.5902/198050985749Ciência Florestal; Vol. 22 No. 2 (2012); 417-422Ciência Florestal; v. 22 n. 2 (2012); 417-4221980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5749/3517Marinho, Nelson PotencianoNisgoski, SilvanaKlock, UmbertoAndrade, Alan Sulato deMuñiz, Graciela Inês Bolzon deinfo:eu-repo/semantics/openAccess2014-08-26T01:31:42Zoai:ojs.pkp.sfu.ca:article/5749Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2014-08-26T01:31:42Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
