Abstract:
The research had the objective of determining the chemical composition of the wood o f Cedrela odorataL. and its relationship with the chemical properties of the soil in a forest ecosystem; for this purpose, five trees were taken as samples, from which a branch of one meter long of 10 to 20 centimeters in diameter was obtained and the analyses of ash, extracts, lignin and holocellulose of each sample were carrie d o ut; th e analysis of the level of pH, phosphorus and nitrogen of the soil was made. For statistical analysis, the non-parametric Kruskal-Wallis test was used with the Dunn test, and a bivariate correlation of Spearman was applied. In general, it was obtained that the holocellulose (62,97 %), is the most abundant component, followed by lignin (30,15 %) and with a lower percentage the content of extractable (5,64) and Ashes (1,24 % ). Th e soil where the individuals grew is very acidic (pH of4,70) with a medium p h os p ho rus level (33,74 ppm), and a high level of nitrogen (165,24 ppm). The relationship betw ee n the chemical properties of the wood and each of the chemical properties of the soil resulted in four relationships, two positive (phosphorus -lignin with a s ign if ic a n c e o f 0.1 and nitrogen -holocellulose with a significance = 0,01) and two negative (p H -a s h with a significance of 0,01 and nitrogen -lignin with a significance value of 0,04).
