Sunflower seeds have a high fat content that causes rapid seed deterioration. The objective of this experiment was to determine the effects of coating of sunflower seeds with polymer (Flare-2, Centor Thai) mixing with vitamin c and chitosan at the concentrations of 0 (control) 2 4 and 6 ppm (120 ml/100g seed). The coated seeds were stored in plastic bag for 6 months at 10 deg C. The results showed that the seed germination of coated seeds for all treatments after 4 months of storage was not significantly different from the initial value. However, after 5 and 6 months of storage, the control treatment had the lowest germination percentage of 76 percent and it was lower than the coated seeds with polymer mixing with vitamin C and chitosan treatments (87-95 percent). Seed vigor of coated seeds decreased with the longer storage time in every treatment. Germination index (GI) and seedling growth
