Both chemical and visual estimations of starch reserves in woody tissue demonstrated that affected trees had lower reserves than healthy trees. The starch deficit appears to be a causal factor in the condition. It is suggested that this deficit may be caused by an imbalance between crop and vegetative growth, associated with low soil fertility
