The average height of a culm in
the sites selected for this study was 23.65 m.
Diameters and wall thickness were respectively
basal segment (11.5 cm, 1.82 cm), middle segment
(11.05 cm, 1.32 cm) and apical segment(5.84 cm, 0.89 cm) (Table 4; figures 9 and 10).
In G. angustifolia, the internodes have an average
length of 20 to 35 cm. The longest length
between internodes was registered in the middle
segment (35 cm) and the shortest in the basal
segment (20 cm) (Table 4). The average diameter
of the G. angustifolia culms studied ranged
