Method for Obtaining Better Germination of Green Panic (Panicum maximum var. Trichoglume Eyles) Seed

Description
Because germination of green panic seed was unstable, a series of tests were performed to establish methods for obtaining better germination of this seed earlier than usual after it is harvested. In this report key points of the methods formulated are described. Seed ripened at 21 °C showed a higher germination percentage in its early age ( 4 months after harvest) than that ripened at 25°C or 29°C. Excellent early age germinations were realized by drying seed slowly immediately after harvest, especially by spending as much as a month gradually drying seed at 20°C and stirring every few days. Heating (storage at 30°C) expressly improved germination of seed dried slowly, and hulling (removal of bracts) also improved .germination. Seed ripened at about 21 °C and treated by a combination or slow drying, heating and hulling showed a final germination of 84% and rapid germination 3 months after harvest when seed normally processed hardly germinated at all. The most effective method for obtaining better germination with early age green panic seed was slow drying immediately after harvest. Slow seed drying seems to surpress germination inhibitors.
