Chemical composition of lower wood in mature individuals of thirteen species of Cactaceae.

The contents are reported in the total dry weight percent (% w/w). The standard deviation in each case was less than 10% on average. (S1 Table, S3 Dataset. Supporting information for the S/G ratios) * Species where the content of lignin in the lower wood was different between adult individuals, the difference in the lignin content in adults of F. pilosus was ≈ 19% and in E. platyacanthus was ≈ 23%, the other components of the wood vary proportionately. Moreover, in these dimorphic species occurs a change from WBTs wood in juvenile stages to fibrous wood in the mature ones.
