Abstract

Soluble and structural carbohydrate performance of elephant grass clones (Pennisetum purpureum) CUBA CT 115, CUBA CT 169 and king grass cut2, 4 and 5 times a year with sugar cane (Saccharum officinarum) varieties Jaronu 60-5 and clone 21 cut once and twice a year were analysed for 5 years in a random block design with 5 replications. Significant differences were found for acid detergent fibre of leaves, stems and the whole plant, the lowest values (P < 0.001) for the latter were found in Pennisetum clones (42.31-42.92%) cut five times a year. Significant differences were also encountered for cell walls of leaves and stems and the greatest amount (P < 0.001) was in the whole king grass plant (78.79%) cut four times a year. The content of lignin in leaves and stems showed significant differences (8.66-14.68%), but the highest accumulation was observed in the whole king grass plant (13.82%) cut twice a year. Cellulose also offered significant differences in CUBA CT 169 (44.64%) cut twice a year and no differences were found for king grass (45.37%) and CUBA CT 169 (46.26%) cut four times a year. The content of hemicellulose tended to decrease as the cutting frequency was reduced. The highest (P < 0.001) percentage of soluble carbohydrates in alcohol was obtained in the leaves (6.95%), stems (52.13%) and the whole plant (47.31%) of Jaronu sugar cane cut once a year. A variation for total water soluble carbohydrates was observed in the leaves (7.42%), stems (54.70%) and whole plant (49.80%) of Jaronu cut once a year. The variation produced by the cutting frequency on soluble and structural carbohydrates of the species studied is discussed.
