Abstract
To investigate the sulfate utilization efficiency in different rape (Brassica napus) cultivars, sulfate uptake are analyzed under complete S-supply level (2.0mM ${SO_4}^{2-}$). This study used ten different genotypes of rape (Mokpo, Tamra, Youngsan, Naehan, Saturnin, Akela, Mosa, Capitol, Pollen and Colosse). For comparison of ${SO_4}^{2-}$ uptake among 10 cultivars, leaf number, leaf length and width, root length was also observed. Leaf length and width in all cultivars less variable among the cultivars examined. The longest root was shown in Saturnin (36.3 cm). ${SO_4}^{2-}$ uptake in Saturnin, Youngsan and Mokpo was significantly higher whereas that of Mosa and Pollen was relativety lower. Saturnin and Mokpo which have a high ${SO_4}^{2-}$ uptake exhibited a high ${NO_3}^-$ uptake.
