dc.descriptionResumo 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.
