Germination, emergence, and seed persistence of Panicum miliaceum L.
MetadataShow full item record
The effects of varying levels of temperature, moisture, and seed depth on wild proso millet (Panicum miliaceum L.) emergence were observed. The effects of depth and duration of seed burial and the effects of seed overwintering on the soil surface on modes of seed depletion and persistence were studied. Patterns of wild proso millet emergence in the field were studied under conditions of plus or minus intraspecific and corn competition, and with and without soil disturbance. Emergence occurred over a range of 10 to 40 C with percent and speed of emergence increasing with temperature. Under simulated ...
