Description
Mature seeds harvested from both fungicide-sprayed and unsprayed portions of plots, were stored and used in germination trials to test the effects of length of storage, disease infection and treatment with potassium nitrate solution on germination of guinea grass (Panicum maximum). There was no germination before 14 weeks of post-harvest storage irrespective of fungicidal treatment. Among the fungicide• sprayed seeds, germination was highest with 18 weeks' storage, suggesting a probable inactivity of the embryo when freshly harvested and up to 17 weeks' post-harvest storage. Treatment with potassium nitrate appeared to increase germination in Panicum maximum. For the concentration range of potassium nitrate from 0.25% to 3.0%, germination was highest at the 0.5% concentration and with 10-15 minutes of soaking.' Fungal infection and low seed filling percent possibly contributed to low germination in guinea grass.
