This paper reports the results of studies on the relation between diameter and length of ramie stalks of the Murakami variety to the content, fineness and tensile strenght of the fiber. The stalks were grouped in 7 diameter classes, varying from 4.5 to 10 mm, and according to lenght in classes differing by 10 cm, from 80 to 160 cm. The results showed that the stalks of smallest diameter had the highest fiber content; at the same time, their fiber was correspondingly the finnest. The tensile strength of the fibers had no relation to stalk dimensions. In relation to the fiber characteristcs studied, no difference was found that could be related to stalk length.
