In this article:
Typical symptoms on Sultana grown in solutions containing deficiencies or excesses of single elements are described.
The vines were grown in solutions deficient in nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, zinc, boron, and manganese, and in solutions with excessive concentrations of sodium, chloride, boron, nitrogen, sulphur, zinc, and manganese.
Foliar symptoms produced by these treatments, except for those treated with excesses of nitrogen and sulphur, are shown in colour plates.
A key based on the characteristics of the symptoms, the position on the shoot where symptoms first appear, and the development of chronic symptoms is also presented to aid visual identification of these nutrient aberrations.
