Resumo: Changes in leaf anatomy were evaluated in genotypes of Brachiaria brizantha, Brachiaria decumbens, Brachiaria ruziziensis and three Brachiaria ruziziensis clones through tissue proportion in internerval and midrib regions at three regrowth ages. Plants were grown and cutting was performed after 60 days. Further, leaves were sampled at 8, 15 and 29 regrowth days and processed with usual plant microtechnique. The internerval region showed higher parenchyma percentage at 15 days for Clone 95 and similar values at 15 and 29 days for Clone 1. The proportion of vascular bundles was lower after 15 days in Clones 1 and 95 and 29 days in B. brizantha. In the midrib, the parenchyma proportion was higher at 29 days in B. brizantha and lower at 15 days in B. ruziziensis. The proportion of vascular bundles was higher at 8 days in B. decumbens, B. brizantha and Clone 1, and lower at 29 days for Clones 97 and 95 and at 8 days in B. ruziziensis. Therefore, the regrowth age modifies the percentage of leaf tissues in Brachiaria genotypes, in which the fibers and vascular bundles increase at 29 days and 8-day-old leaves are not fully developed.

As plantas foram cultivadas e cortadas após 60 dias. As folhas foram amostradas aos 8, 15, 29 dias de rebrota e analisadas pela metodologia de microtécnica vegetal. Na região internervural, a proporção de parênquima foi maior aos 15 dias para o Clone 95, e aos 15 e 29 dias para o Clone 1. Proporção de feixes vasculares foi menor aos 15 dias para os Clones 1 e 95 e aos 29 dias para genótipo B. brizantha. Na nervura central, a proporção de parênquima foi maior aos 29 dias para B. brizantha e menor, aos 15 dias, para B. ruziziensis. Proporção dos feixes vasculares foi maior aos 8 dias para genótipo B. decumbens, B. brizantha e para o Clone 1, e menor aos 29 dias para os Clones 97 e 95; aos 8 dias, para genótipo B. ruziziensis. Portanto, a idade de rebrota modifica a porcentagem de tecidos foliares em genótipos de Brachiaria; contudo, fibras e feixes vasculares aumentam aos 29 dias; aos 8 dias, as folhas não estão totalmente desenvolvidas.Editora da Universidade Estadual de Maringá (Eduem)2019-03-19T13:13:05Z2019-03-19T13:13:05Z2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMAURI, J. et al.
