Abstract

Tall fescue (Festuca arundinacea Schreb.) reportedly produces rhizomes, but the anatomy, morphology, and growth of rhizomes have not been adequately studied. Our objective was to determine if lateral shoots were true rhizomes and distinguishable from tillers. Rhizomatous and nonrhizomatous genotypes were selected from the field for studies and comparisons with rhizomes of Kentucky bluegrass (Poa pratensis L.). Microscopic examination showed rhizomes of both species had a spongy cortex, a large pith area, one to two rings of alternately spaced vascular bundles, and sclerified bundle sheaths which merge with a ring of sclerenchyma separating the vascular tissue from cortical parenchyma. In contrast, tillers of tall fescue had numerous and closely spaced vascular bundles, and a densely packed pith region. Based on overall structure, pattern of growth, and internal anatomy, some tall fescue genotypes spread by true rhizomes, equivalent to those of other grasses.
