Abstract
The difference in concentration of some mineral elements in the tissue and bark of two cultivars of white Yam (Dioscorea rotundata) sampled randomly from Kaduna State of Nigeria is reported. The elements report ed were determined by Flame atomic absorption spectrometry and Flame e mission spectrometry. The Ca, Fe, Mg and K contents were significantly different contrary to concentration of Cu, Na, Ni and Zn showed insig nificant differences. In both cultivars, Fe showed the highest bark/ti ssue ratio while K had the lowest.
