Abstract
Ultrastructural studies of root cortical cells of Raphanus sativus L. seedlings experimentally exposed to 0 - 7 mgL Cr revealed small electron dense granules especially in preplasmic zone.Root cortical cells of control seedlings grown in the absence of Cr3+ additions were void of any granules. X-ray microanalysis of the granules provided that Cr was the predominant element while lower amounts of Fe , Zn and Mn were also measured in the granules . Presence of chromium deposit inclusions in the cells may be regarded as plant detoxifying mechanism to maintain relatively low cytoplasmic concentration of the element.
