经一系列考察研究证实,我国50年代后期于大兴安岭发现的所谓“漠河红松”,应属西伯利亚红松Pinus sibirica,而并非红松P.koraiensis。天然红松实际上不入大兴安岭。西伯利亚红松主要覆被西、中西伯利亚地区。在我国大兴安岭,仅偶见于西北隅,属首次发现。种的鉴定,除根据一般常用形态性状鉴别外,还以解剖镜、光学显微镜与扫描电镜相结合,对针叶表皮上的下陷气孔外口及其在角质层上的印痕,进行了一系列的比较研究。结果发现,西伯利亚红松的气孔外口,乃至表皮细胞,也与红松明显不同,应视为一可靠鉴别特征。
After a series of investigations and studies, it is confirmed that the so-called “Mohe Korean pine” found in Daxinganling in the late 1950s belongs to Pinus sibirica in Siberia and not to P. koraiensis. Natural Korean pine does not actually enter the Greater Khingan Range. Siberian pine is mainly covered by West and Central Siberia. Daxinganling in our country, only occasionally found in the Northwest corner, is the first time found. In addition to the identification of common morphological traits, a series of compare research. As a result, it was found that the stomatal orifice, as well as the epidermal cells, of P. siberia were also significantly different from that of P. koraiensis and should be regarded as a reliable distinguishing feature.
