Resumo: | Among the sugar cane potential uses include those related to the extraction of products and byproducts from the stalk. The sugarcane flowering causes morphological and physiological changes in plant and in the presence of pith, promotes changes in the stalk, reducing the raw matter quality. Most of the areas planted with sugarcane in the South-Central region of Brazil are subject to flowering, however, this feature varies depending on the variety used. There are different pith diameters related to the flowered or induced stalks, and damage to the raw matter quality are still controversial. The objective of this experiment was to evaluate the response of cane sugar varieties in relation to the flowering, pith and chemical and technological parameters, and their relationship with the pith degree. The experimental design was a completely randomized with sis treatments (varieties: IAC91-1099-4004IAC94, IAC95-5000, SP81-3250, CTC and RB855536 15) and three replications. Were evaluated the flowering, based on morphological changes in the apical bud, the pith intensity by the percentage determination of internodes occupied by whitish and spongy tissues and and pith diameter, by measuring the diameters of the changes in the internodes, expressed in percentage, in addition to chemical (juice total acidity) and technological (fiber, reducing sugars and sugar cane Pol) parameters. The flowering occurrences were accompanied by higher pith intensity. The flowering induction contributed to the lower raw matter quality, although the pith volume was lower. The pith and flowering did not affected the sugarcane sucrose content. Increases in levels of fiber, sugars and acidity were observed only in cases where the diameter of the area spongeous exceeded 50% of stalk diameter. The variety that had the best and worse response was RB855536 and CTC 15, respectively. |

O florescimento da cana ocasiona alterações morfo-fisiológicas na planta e, na presença da isoporização, provoca modificações no colmo, diminuindo a qualidade da matéria-prima. A maioria das áreas plantadas com cana, na região Centro-Sul do Brasil, está sujeita ao florescimento, no entanto, essa característica varia em função da cultivar empregada. Existem diferentes diâmetros de isoporização relacionados a colmos florescidos e induzidos, e seus danos à qualidade da matéria-prima são ainda controversos. O objetivo deste experimento foi avaliar o comportamento de diferentes cultivares e a relação entre os colmos florescidos e induzidos com a intensidade de isoporização, e o comprometimento do diâmetro do colmo e da qualidade da matéria-prima. O delineamento experimental utilizado foi o inteiramente casualizados, com 3 repetições. Foram avaliados o florescimento, a intensidade da isoporização e o diâmetro da isoporização, além das análises químicas e tecnológicas. As ocorrências do florescimento foram acompanhadas das maiores intensidades de isoporização. A indução ao florescimento contribuiu para a redução na qualidade da matéria-prima, embora o volume isoporizado tenha sido menor. O florescimento e a isoporização não afetou o teor de sacarose na cana. Aumentos nos teores de fibra, açúcares redutores e acidez, apenas foram verificados nos casos em que o diâmetro da área isoporizada ultrapassou 50 % do diâmetro do colmo. A cultivar que obteve o melhor desempenho foi a RB855536 e o pior a CTC 15.Univ Estadual Paulista UNESP, CNPq, Fac Ciencias Agr Vet FCAV, Jaboticabal, SP, BrazilUNESP, FCAV, Dept Tecnol, Jaboticabal, SP, BrazilFac Tecnol FATEC, Jaboticabal, SP, BrazilUniv Estadual Paulista UNESP, CNPq, Fac Ciencias Agr Vet FCAV, Jaboticabal, SP, BrazilUNESP, FCAV, Dept Tecnol, Jaboticabal, SP, BrazilUniversidade Federal de Uberlândia (UFU)Universidade Estadual Paulista (Unesp)Faculdade de Tecnologia do Estado de São Paulo (FATEC)da Silva Neto, Helio Francisco [UNESP]Marques, Marcos Omir [UNESP]Tasso Junior, Luiz CarlosCamilotti, FabioBernardi, Juliano Henrique2014-05-20T13:17:41Z2014-05-20T13:17:41Z2011-01-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://www.seer.ufu.br/index.php/biosciencejournal/article/view/7168Bioscience Journal.
