Abstract

Germination test (sand test) of storage condition of treated field corn seed, SW. 5 variety was carried out in 2 conditions, room temperature (25 deg C +- 2 deg C) and control room (13 deg C +- 2 deg C, 45 percent RH.) storage for 6 months. There were 8 treatments including 7S+SPt 360, 7S+ KPS 46, 7S+SW 01/4, SW 01/4+SPt 360, SW 01/4+KPS 46, SPt 360+KPS 46, bacterial suspension KPS 46 and non-treated (control). The result showed that seed storage under different condition affected on seed germination significantly. Seed deterioration rate in condition room lower than in room temperature. For seed treatment, it was found that there were high correlation between seed storage and treated material. Under control room temperature, field corn seed treated with SW 01/4+SPt 360 (S4) gave highest seed germinated to 98 percent. In room temperature seed treated with KPS 46 (S7) gave highest percent of germinated to 72 percent for 4 months after storage and vigor of organic seed treatment gave higher vigor than non treated seed. Moreover, seed moisture content was increased 1-2 percent higher than initial moisture content.
