Bio-polymers determination in Pinus halepensis

Thermal analysis had showed that the decomposition of the plants at about 3 00 degrees was mainly dependent on the cellulose content in dry matter, on account of the flammable evolved gas responsible of forest fires. The estim ation of the fire risk is mainly proportional to the cellulose present. For the Pinus halepensis this risk will be very important for the pine-cones ( green, brown, black), important for the needles, branches, barks. buds, and less important for the soft pine-cones in formation.
