FONTE, Leydi; MACHADO, R; DIAZ, Maykelis  e  BLANCO, D. Morphological characterization of Gliricidia sepium and bromatological composition and sugar proportion in its flowers. Pastos y Forrajes [online]. 2013, vol.36, n.4, pp. 423-428. ISSN 0864-0394.

The study was conducted at the Pasture and Forage Research Station «Indio Hatuey», in order to determine the morphological characteristics of Gliricidia sepium, as well as the bromatological composition and sugar proportion in its flowers. Twenty of 165 G. sepium trees were sampled, which represented 12 % of the total, and each tree constituted a replication. The experimental design was completely randomized and the following morphological variables were measured: total plant height, stem diameter at breast height (DBH) and crown width. In addition, the number of flowers per tree and per hectare was estimated. In the collected flowers the bromatological composition was determined: DM, CP, CF and Ca, moisture and Klason lignin. The mean values were: DBH, 44,7 cm; height, 4,85 m; 295 racemes, with 34 flowers as average each, per tree and an estimated total of 10 030 flowers per tree and 8 986 880 flowers per hectare. The DM was 8,69 %; CF, 32,57 %; Klason lignin, 28,8 %; CP, 7,04 %; and Ca, 0,99 %. The simple sugars detected were: glucose (4,82 %) and fructose (10,36 %), while sucrose showed values of 1,73 %. It is concluded that all the sampled G. sepium trees were typical of the species. The DM percentage of their flowers was low, but the content of CF, CP, Klason lignin and calcium was high. Fructose was the most abundant sugar in the extract and sucrose was the scarcest.
