| Family Scientific Name: | Poaceae | ||
|---|---|---|---|
| Family Common Name: | Grass family | ||
| Scientific Name: | Sporobolus contractus Hitch. | ||
| Common Name: | Spike drop seed | ||
| Species Code: | SPOCON | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Time To Grow: | 0 | ||
| Pre-Planting Treatments: |
Mechanical injury of the caryopis or covering layers resulted in 67% germination. Pretreatment with potassium nitrate resulted in 47% germination. Seeds are placed in cold moist stratification for 28 days. Germination occurs at 35D/20N C alternating temperature cycle. In another study, germination occurs at 30D/15.5N C alternating temperature cycle. Germination was greater in light than dark; and light was equal to dark. Physiological dormancy of seed is overcome by 28 day cold moist stratification treament and germination tempertures of 35D/20N. |
