摘　　要：对五味子科 2属 1 9种植物导管分子的结构进行了比较观察。结果表明 :2属均以具缘纹孔导管为主 ,少有梯纹和螺纹导管 ,南五味子属多数种还有梯孔纹导管 ;2属导管长度和宽度差异很小 ,长 /宽比值有差异 ;根据穿孔板的结构可分为 2种形式 :( 1 )单穿孔板 ,这类穿孔板较普遍存在 ;( 2 )梯形穿孔板 ,发现 2属中的红花五味子 (Schisandrarubriflora)、五味子 (S .chinensis)、翼梗五味子 (S .henryi)、铁箍散 (S .propinquavar.sinensis)和黑老虎 (Kadsuracoccinea) 5种植物的导管分子具有此类穿孔板。其中五味子属中的五味子导管分子只具有梯形穿孔板 ,无单穿孔板 ,但横条较少 ,多为 2～ 3条。This paper deals with comparative study on the structures of vessel elements in 19 species of 2 genera of Chinese Schisandraceae. Pitted vessels were commonly observed in the two genera,spiral vessels and scalariform vessels were occasionally found;The length and the width of vessels show little difference,but length/width has difference between two genera. Two types of perforation plate were recognized. (1)The simple perforation plate was comparatively universal and widespread. (2)The scalariform perforation plate was demonstrated in S.rubriflora,S.chinensis,S.henryi,S.propinqua var. sinensis of Schisandra and K.coccinea of Kadsura . The vessel elements of Schisandra chinensis showed only typical scalariform perforation plates with fewer bars.
