Abstract
Chromium-51-labeled Cr(III) or Cr(VI) was added in seven increments to plant nutrient solutions, to a final level of 0.044 ppm. The Cr was added over a 14-day period at flowering stage in bean and wheat plants. At maturity bean plants contained about 55% and wheat had removed 81% of the added /sup 51/Cr. Bean roots contained about 92% and wheat roots 95% of the total plant /sup 51/Cr. Seeds contained only 0.02 to 0.1% of the total plant /sup 51/Cr. Uptake and translocation of /sup 51/Cr differed only slightly between the Cr(III) and Cr(VI) sources. Most of the /sup 51/Cr in fresh bean leaves was present as a soluble low molecular weight anionic complex that was not associated with any subcellular organelle. Rats fed the /sup 51/Cr-labeled bean leaves retained less than 0.5% of the dose after 48 hr.
