High-resolution 31P nuclear-magnetic-resonance (NMR) spectra are reported for oil-palm (Elaeis guineensis) cells in suspension culture. The spectra are a signicant improvement on the results that have appeared for other cultures and they are comparable with the spectra of the meristematic tissue in seedling roots. The NMR technique was used in parallel with other analytical methods to investigate the growth characteristics of the suspension culture, indluding the effect of 2,4-dichlorophenoxyacetic acid.
