Boron deficiency interacts strongly with environmental factors. Whilst the mechanisms governing these interactions are poorly understood, they stem from the need for a continuous supply of B to growing tissues in the plant. Boron deficiency occurs when the rate of supply of B to growing tissues falls below the rate of demand. It can occur when demand increases as a result of increased absolute growth rate or as internal requirements increase to cope with environmental stresses such as high light intensity or low temperature. Supply may be depressed by environmental factors such as low soil water and low temperature which depress B uptake by roots. That these factors act in a dynamic rather than a static manner adds to the challenge of predicting when and where B deficiency will occur and its impact on seed yield in wheat crops.
