Summary
By means of electron microscopy and X-ray energy spectroscopy (CORA in the transmission mode) it was shown that lanthanum may enter the cytoplasmic phase of undifferentiated cells in barley root tips. The nucleolus in particular proved to be a site with a high affinity for lanthanum. This finding is discussed in relation to the inhibition of root growth which has been reported to occur when root tips are exposed to polyvalent cations.
