  Chemical Characterization of Selected Tree Legumes as Indices for Their Litter Quality
 
 
Titel: Chemical Characterization of Selected Tree Legumes as Indices for Their Litter Quality
Auteur: M.B. Oyun
Verschenen in: Journal of applied sciences
Paginering: Jaargang 6 (2006) nr. 10 pagina's 2321-2324
Jaar: 2006
Inhoud: Leaf pruning from several legume species: Gliricidia sepium, Cajanus cajan, Albizia zygia, Albizia ferruginea, Leuceena leucocephala, Dalbergia latifolia, Acacia auriculiformis were analysed for some critical litter quality indices such as total carbon, nitrogen, lignin and polyphenols. Total C was estimated as 50% of its ash free dry weight and total N was determined by Kjeldahl method while lignin content was determined from the acid detergent fibre. The polyphenol content was extracted in 70% aqueous acetone after initial depigmentation with diethyl ether containing 1% acetic acid and determined as tannic acid equivalent using Folin Ciocalteu reagent. Total C ranged from 42.8% in Albizia zygia to 49.6% in Acacia auriculiformis while N ranged from 3.9% in Acacia and Albizia ferruginea to 4.8% in Gliricidia sepium. Gliricidia had the lowest polyphenol content (2.3%) while Acacia contained the highest value (7.7%). The lignin content varied from 23.9% in Gliricidia to 49.7% in A. Auriculiformis. Based on the leaf chemical constituents, Gliricidia sepium was rated as high quality litter while Acacia auriculiformis was rated as low quality litter.
