摘要
秦岭冷杉和巴山冷杉树脂道的分布与结构特征进行了解剖学研究,结果表明:冷杉树干皮层、枝条皮层、针叶及球果中均有树脂道分布,都能分泌树脂,以树干皮层和针叶中的树脂含量高,具有采集利用价值。
Describes the anatomic distribution and structural featu res of resin ducts of Abies chensiensis Van.Tiegh.and A.fargesii Franch. The resin ducts were found in cortex of trunk, branches, needles and cones. The resin contents are much higher in trunk cortex and needles than that in other tissues.Collection and utilization of fir resins were also described.
