| Abstract: | Inorganic ions in plants can be determined by using the near-infrared spectral(NIRS) technique,because they combine with the organic groups that have NIRS absorptions.The present study explored the feasability of applying near-infrared diffuse reflectance spectrometry for rapid determination of Cu,Zn and Cd contents in sweet potato leaves and stems.Sixty-seven leaf and same number of stem samples were collected from sweet potato plants grown under different fertilizations.The partial least square method was... |
