Other claims from this paper (6)
- Intervention effect ABA treatments enhanced anthocyanin content of Redglobe grape skins in two of three years.
- Recommendation ABA applied at about 300 mg/l at veraison may be required to reliably increase grape pigmentation.
- Intervention effect ABA treatment did not change anthocyanin composition of grape skins.
- Intervention effect Applications of ABA had few effects on grape fruit size or composition.
- Intervention effect ABA applications caused grape fruit softening, which the authors regard as undesirable.
- Recommendation Colour measurements may be needed to evaluate the effect of cultural practices on colour in table grapes.
