摘　　要：对四川独活属13种植物进行了解剖学研究.根据独活属植物根的次生韧皮部远比次生木质部发达的特点,确定独活属植物的根是典型的贮藏型根.研究结果表明:分泌道存在于中柱鞘和次生韧皮部,而不存在于次生木质部和周皮.根部分泌道的数量与药用价值相关,接受独活属植物中分泌道丰富的独活H.hemsleyanum、短毛独活H.moellendorffii、平截独活H.vincinum、白亮独活H.candicans、永宁独活H.yungningense等种为独活属主要的药用植物.This paper reports the result of anatomical studies on the root of 13 species in the genus Heracleum from Sichuan. The secondary phloem is larger than the secondary xylem in the Heracleum, which is the typical storing root. The result shows the secretary canals exist in the pericycle and the secondary phloem of the mature root except in the secondary xylem and the periderm. The quantity of secretary canals in the root is relative to the medical use. H. hemsleyanum, H. moellendorffii, H. vincinum, H. candicans, H. yungningense etc have abundance of secretary canals. They are the main medical plants of Heracleum.
