5 mm laciniate long) and puberalous Inner surface of the finely puberalous glabrous except around petals throughout the basal ligule Ligule narrowly triangular, finger-like, to 2 mm to 4 mm long long Anthers 2-2.
Plants perennial, tufted, caespitose, with a knotty rhizomatous base, the rhizomes short and thin; culms 15-30(-55) cm tall; nodes 2-3, branching below, puberulent to scabrellous; internodes short covered by the sheaths, glabrous, puberulent to shortly hirtellous near the nodes; leaves basal, sheaths 3-4(7) cm long, longer than the internodes, the upper with a reduced blade below the synflorescence, the lowermost purple and short-hirsute, the next green and glabrous, margins shortpilose; ligules 0.
5 mm long, connate for the basal one-third or more; lobes of the outer ligule present 3-8 mm long; culm leaf sheaths 24-29.
Leaves 6-14, essentially basal; sheaths 3-13 cm long, whitish to stramineous, strongly ribbed, old sheath bases brownish, becoming slightly fibrous, the inner band whitish-hyaline to brown, membranous, finely veined, the apex concave; ligule rounded, 1-4(-9) mm long, the free portion brownish, 0.
The fungicide applications were performed at the plant GS 22 (Main shoot and 2 tillers), GS 31 (Swelling 1st node detectable), GS 39 (Flag leaf ligule just visible), GS 45 (Full-boot, boot above ligule of 2nd last leaf) and GS 56 (50% of spikes visible), according to the diagrammatic scale of ZADOKS et al.
Expanded leaves were measured from their ligules, expanding leaves from the ligule of the last fully expanded leaf, and the measure of senescent leaves considered only the green portion of the leaf blade.
Another relevant characteristic for the cited classification was the presence of a coleoptile (also called ligule or ocrea), which was used to divide palms with remote germination into ligulate and nonligulate seedlings.
The ligule is a blunt membrane covered by short prickle trichomes.
At three ligule stage (V3), seedlings were thinned to one plant per pot.
We describe the ultrastructure of leaf blade, spikelet, ligule and auricles.
