Distribution of holocellulose, lignin, and ash contents, with holocellulose-to-lignin ratio (H/L) indicated for each sample: a Chinese fir samples: red bars represent holocellulose content, blue bars represent lignin content, orange bars represent ash content, and "H/L" denotes the holocellulose-to-lignin ratio. b Chinese cypress samples: same color coding applies (red = holocellulose, blue = lignin, orange = ash), with "H/L" indicating the holocellulose-to-lignin ratio.
