Germination ecology of Chloris truncata and its implication for weed management
Fig 6
Effect of sorghum residue amount on seedling emergence of Chloris truncata after 21 d of incubation at 25/15°C day/night temperature.
The line represents an exponential decay model fitted to the data. The arrow shows the sorghum residue amount to inhibit 50% emergence. Vertical bars represent standard error of mean.
