摘　　要：本文通过对蓬蘽悬钩子根和茎的解剖学研究,发现其周皮的发生部位,均不同于一般植物,即其根自外皮层发生,而茎则由中柱鞘起源,这就为植物学及植物解剖学的教学与科学研究工作,积累了一份新资料。The anatomical study of Rubus crataegifolius Bunge showed that the original position of periderm on its root and stem differs frpm general plants in that the periderm arise 9 from exodermis on root but from pei-cycle on stem.In addition, root phellem is composed of a special protective tissue-polyderm, while the stem phellem is made up of suberized cells and unsuberized pheloid cells.
