Calcium sulfate ameliorates the effect of aluminum toxicity differentially in genotypes of highbush blueberry (Vaccinium corymbosum L.)

The effect of gypsum (CaSO4) amendment in the reduction of Al phytotoxicity of blueberry cultivars differing in Al resistance (Legacy and Brigitta, Al-resistant and Bluegold, Al-sensitive) was studied in a Hoagland's nutrient solution under acidic conditions for 2 weeks. Treatments were: Contro...

Treatments were: Control (Hoagland solution), 2.5 mM CaSO4, 5 mM CaSO4, 100 μM Al (AlCl3), 100 μM Al + 2.5 μM CaSO4, 100 M Al + 5 mM CaSO4.
