Abstract

Abstract This study involved analysing the carbon-13 isotope ratio (δ 13 C) of cellulose, lignin, and whole wood powder of Balanites aegyptiaca to determine the optimal substrate for future ecophysiological studies. From seven different trees (i.e., three from the Sudanian zone and four from the Chadian Sahelian zone), 21 samples were taken for this study. Identical variation trends were observed with cellulose, lignin, and whole wood powder, with δ 13 C values for cellulose always higher than for the other substrates, although the trees were located under different climatic conditions. The means obtained were −26.0 ‰, −28.7 ‰, and −27.1 ‰, for cellulose, lignin, and whole wood powder, respectively. Spearman’s correlation test, which was used to analyse relationships between the results, revealed a strong correlation ( r 2 = 0.93) between the δ 13 C cellulose values and those of whole wood powder from B . aegyptiaca , as well as between the δ 13 C cellulose values and those of lignin ( r 2 = 0.73). This strong correlation between cellulose and wood powder results, and between cellulose and lignin, suggests that the isolation of cellulose is not necessary for δ 13 C analysis of B . aegyptiaca wood.

埃及巴兰木纤维素、木质素和全木粉稳定碳同位素比值的比较研究

摘要本研究通过分析埃及巴兰虫(Balanites aegyptiaca)纤维素、木质素和全木粉的碳-13同位素比值(δ 13c)来确定未来生态生理研究的最佳底物。从七棵不同的树(即三棵来自苏丹地区，四棵来自乍得萨赫勒地区)，为本研究采集了21个样本。在不同的气候条件下，纤维素、木质素和全木粉的δ 13c值变化趋势相同，纤维素的δ 13c值始终高于其他基质。纤维素、木质素和全木粉的平均值分别为- 26.0‰、- 28.7‰和- 27.1‰。利用Spearman’s相关检验对结果之间的关系进行分析，结果表明木粉的δ 13c纤维素值与木粉的δ 13c纤维素值有很强的相关性(r 2 = 0.93)。δ 13c纤维素值与木质素值之间(r 2 = 0.73)。纤维素和木粉之间以及纤维素和木质素之间的强相关性表明，分离纤维素对B的δ 13c分析是不必要的。aegyptiaca木头。
