Abstract: | The effect of rain on foliage elemental composition, especially B, was assessed using samples of wheat collected at three
harvests from a field trial conducted in soil containing excessive levels of B. Moderate rainfall substantially decreased
both the B concentration and content of whole shoots and young leaves. The change in B concentration due to rain suggests
that foliar analysis is unreliable for diagnosing B toxicity. For the other elements examined (Ca, Cu, Mg, Mn, Mg, P, S, Zn),
rainfall had little effect. |
