| 摘 要： | 在森林防火期内,用自行设计的耐火试验装置对云南松和华山松的带叶小枝进行耐火性试验,并实时电脑采集针叶的受热温度,试验结束,立刻取出样品,冷却后用4%红四氮唑溶液染色判别针叶的死活,试验结果表明,云南松针叶的耐火性强于华山松针叶,并且枝径越大的针叶耐火性越强.

| Abstract: | Fire resistance experiments on needles fire resistance from Pinus yunnanensis and P. armandii were implemented during forest fire season with equipment specially designed, and temperature of needles was real-time determined. Mortality rate of needles was calculated based on data of tested needles soaking with 4% of 2,3,5-triphenyltetrazolium chloride (TTC) solution. The results showed that fire resistance of P. yunnanensis needles was better than that ofP. armandii ones, and that of needles from larger branch was better than that from smaller ones. |
