Family Scientific Name: Poaceae
Family Common Name: Grass family
Scientific Name: Tripsacum dactyloides (L.) L.
Common Name: Eastern gamagrass
Species Code: TRIDAC
General Distribution: T. dacytloides is a widespread North American species that ranges from the central and southeeastern United States into Mexico and South America in grasslands and prairies.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Time To Grow: 0
Propagule Processing: Seeds exhibit physiological dormancy.
Pre-Planting Treatments: Seeds are placed in cold moist stratification for 42 to 56 days.
Germination occurs at 30D/20N C alternating temperature cycle.
In other studies, mechnaical injury of caryopsis or covering layers reluted in 86% germination. Application of gibbrellic acid resulted in 82% germination.
