Effect of seed treatment emulsifiers on seed quality and membrane function in maize.

Three commonly used seed treatment emulsifiers, Triton X-100, Proprietary-adjuvant A and Proprietary-adjuvant B, were applied at 13.8 (recommended rate) or 55.1 mg/kg seed to 4 maize seed lots differing in genotype and seed vigour. Seed quality was measured by cold germination test, leachate conductivity and sugar leakage. Membrane repair capacity during imbibition, membrane lipid composition and thermal properties were determined. Seed and seedling performance as indicated by germination tests showed no significant difference between control and treated seed in the 2 high-vigour seed lots. All 3 emulsifiers, especially at high treatment rates, significantly reduced the performance of the 2 low-vigour seed lots. Conductivity and cold test germination were not related. However, a high correlation was found between sugar leakage and cold test germination following emulsifier treatment. The occurrence of membrane repair and the associated changes in phospholipid composition and thermal properties i

n the emulsifier-treated seed indicate a modification of the membrane function due to the emulsifier treatments.
