Two greenhouse sand culture experiments were conducted to investigate the influence of bean yellow mosaic virus (BYMV) on growth and elemental composition of ‘Dark Red Kidney’ beans. Virus concentration within infected beans increased rapidly between 4 and 8 days after inoculation. Symptom expression, growth reductions, and changes in the elemental composition of infected plants were associated with this increase. Virus distribution within the plant varied with the position of the trifoliate leaf or plant part sampled. In addition, symptom expression on the trifoliate leaves at different positions on the plant varied greatly. Changes in the plant nutrient element levels caused by virus infection were first detected 8 days after inoculation. Calcium and Mg concentrations were significantly lower in basal leaves of infected plants than in corresponding tissue from controls. In contrast, Mn and Zn tended to concentrate in infected trifoliate leaves. Total accumulation of individual elements in samples of infected second and third trifoliates was significantly reduced by BYMV. The lower total accumulation of elements in infected trifoliates reflected dry weight reductions due to virus infection. Symptom expression did not appear to be correlated to an imbalance of any one specific element.
