安徽省岳西县来榜区的方刚岭在海拔970—1350米处,生长一种五针松树,俗名“五针松”。这种松树常与黄山松(Pinus hwangshanensis Hsia)、麻栎类(Quercus spp.)混生一起,大者高达20余米,胸径50余厘米。郑万钧教授等定其名为安徽五针松(Pinus anhweiensis Cheng et Y.W.Law)。本文试图从安徽五针松与华山松的木材构造比较观察,借以验证新种的建立。一、木材通性树皮:薄,棕褐色,鳞片状剥落。边材:近白色至浅黄白色,与心材区别显明,狭窄。心材:淡红褐色至浅橙黄褐色,暴露空中颜色较深。生长轮:明晰,树干周围部分因年轮过狭常不明显;中至狭,均匀;年轮间介以深色晚材带;早
Fang Gangling from Yixi County, Anhui Province, is growing 970-1350 meters above sea level and grows a five-needle pine tree with the common name of “Pinus pinanion.” This kind of pine tree is usually mixed with Pinus hwangshanensis Hsia and Quercus spp., The largest one is more than 20 meters and the diameter is more than 50 centimeters. Professor Zheng Wanjun named its name Pinus anhweiensis Cheng et Y.W.Law. This paper attempts to observe the wood structure of Pinus tabulaeformis and Pinus armandii in Anhui Province to verify the establishment of new species. First, the wood bark bark: thin, brown, scale flake. Sapphire: nearly white to light yellowish white, with heartwood difference is obvious, narrow. Heartwood: light reddish brown to light yellowish brown, darker sky exposure. Growth wheel: clear, part of the trunk around due to the narrow and often not obvious; medium to narrow, uniform;
