Abstract
Container-grown `Formosa' azalea plants were affected by irrigation water quality. Sodium (200 ppm), supplied by NaHCO3 and NaCl, inhibited plant growth and diminished plant quality. Observable symptoms were tip-burn, marginal necrosis, leaf curling, and eventual defoliation. There was a negative relationship between leaf tissue calcium and magnesium and higher rates of sodium from NaHCO3. Leaf tissue Cl levels were higher in the higher NaCl treatments. Sodium treatments inhibited root growth. Plants in NaHCO3 treatments accumulated more Na than did plants in NaCl treatments. Media pH and sodium levels following 12 months of sodic irrigation far exceeded acceptable levels for producing marketable container-grown `Formosa' azalea plants.
