Fineness and length of fiber of ten ramie varieties

A study concerning the fineness and length of the following international varieties of ramie (Boehmeria nivea Gaud.) is reported: Saikeisheishin-Shun, London, Tatsutyama, Izu-Kairyo, Chiayi, Tsuannan n.° 2, Toakan, Kokuhi, E 49-63 and Tatsuka-Kairyo. This study was based on fibers obtained from ninety five to hundred three old stalks of the ramie varieties produced in the State of Sao Paulo, Brazil. The Chiayi had the higher average fineness (Nm = 1536,8) and the E 49-63 had the lower average fineness (Nm = 1101.6). The varieties E 49-63, Tatsuka-Kairyo e Saikeisheishim-Shum had the longer fibers (average of 172.3; 167.9 and 168.6 mm, respectively). Kokuhi, London, Tatsutyama Tsuannan n.° 2 and Toakan had the lower fiber length (average of 160.8; 160.1; 155.0; 158.9 and 161.0 mm, respectively). The fibers classified in short, median and long, showed that the varieties of high average length fiber were more uniform than varieties of low average length fiber. The results obtained may be used by the ramie industry for production of different kinds of manufactures and also by the breeders in order to establish any breeding and selection program.
