Modeling on Fire Resistance of Pinus yunnanensis Needles

Abstract

Abstract: Fire resistance experimentations of the needles of P. yunnanensis were tested during the highly dangerous period of forest fire in 2009 with experimental equipment designed by the authors. Discrimination post-heated mortality based on the colors of needles soaked with 1% 2,3,5-triphenyltetrazolium chloride(TTC) solution, and the mortality rate was accounted. The mortality rate model of needles was established. The results showed that the main factors influencing fire resistance of the needles were arranged in order of temperature, heating time, average length of needles, and sheath could protect needles under high temperature.

Key words: Pinus yunnanensis, needle, fire resistance, 2, 3, 5-triphenyltetrazolium chloride (TTC)
