Algumas características de variedades de rami e suas correlações com o teor de fibra Some characters of ramie varieties and its correlations with the fiber content

Algumas características, como peso de caules verdes com folhas, de caules verdes sem folhas, de duzentos e cinqüenta milímetros de caules verdes e secos, de fibra seca, teor de umidade do caule, comprimento e diâmetro de caule, foram estudadas em doze variedades internacionais de rami (Boehmeria nivea Gaud.). As variedades apresentaram valores diferentes para as características estudadas. Foi efetuado estudo de correlação entre o teor de fibra e características, para verificar o grau de associação existente entre elas, encontrando-se algumas correlações significativas.<br>They were tested some agro-botanical and technological characters of ramie (Boehmerict nivea Gaud.) and their simple and partial correlations. In this study the following international varieties were considered. Hakui Ibgou, White Skin, Taiwan Hakushi, Shalien n.° 1, Hsi-Ching-Chin-Hsin, Banmethuot, Miya-saki 112, E 47-1, Murakami, P.I. 87.521, Kagisei, and Yilan n.° 1. The characters studied were: weight - green stalk with leaves, green stalk without leaves, two hundred fifty milimeters of green and dry stalk, dry fiber, - fiber content in green and dry stalk, leaves content, stalk humidity content, and length and diameter of stalk. Considering the characters tested the varieties differed significantly. For certain varieties there were obtained significative correlations among fiber content and some characters studied. The results of this study must be considered by the breeders in the selection works of ramie
