The anatomy of the leaf of Phaseolus vulgaris L. was similar when grown at 0.04 and 0.50 ppm Cu without Fe and with 0.50 ppm Cu-Fe tartrate; necrosis was most severe in the latter. Stems showed no cellular abnormalities. Compared to the controls and other treatments, however, the number of xylem and tracheary elements was less in plants grown at both levels of Cu without Fe and with 0.50 ppm Cu-Fe tartrate. Stunting of roots and shoots occurred when plants were grown with high levels of Cu or without Fe. With high Cu, blunt enlarged root tips resulted from severe hypertrophy and hyperplasia. Lateral roots were initiated within 0.4 mm from the promeristem and fewer meristematic cells were present. Anatomical symptoms characteristic of high Cu were absent when FeEDTA was used as the source of Fe. 23 references, 20 figures, 1 table.
