Cunninghamia

 

a genus of evergreen conifers of the family Taxodiaceae. The crown is narrowly pyramidal. The leaves are linear-lanceolate, sharp-pointed, more or less spirally arranged, and shining. The cones are 3–4 cm long, roundish ovate, with greatly reduced seeds; they mature in the first year and do not fall off the tree. The seeds are narrowly winged. There are two known species. Cunninghamia konishil is native to Taiwan. The China fir (C. lanceolata) is widely distributed in the temperate regions of China, where its soft, lightweight, aromatic, and rot-resistant wood is used for buildings and various wood products. The China fir is cultivated as an ornamental on the Black Sea Shore of the Caucasus, where it grows and propagates well.

PP was an uneven-aged stand which was only composed of 1-5-year-old plants, while China fir was an even-aged stand of 15-54 years in tree age, therefore, the mean aboveground carbon sequestration of PP and China fir stands were 8.
In contrast, the mean aboveground carbon sequestration of Masson pine and China fir stands increase with increasing tree ages up to 12-15 years and decrease slowly thereafter.

The reason is that at 130[degrees]C and 150[degrees]C , lignin and other amorphous region in China fir degraded first along with the proceeding of liquefaction, whereas the crystalline region of the cellulose wasn't damaged, which makes relative crystallinity go up.
