Fig 1.
Effect of alternating day/night temperatures and light regimes on seed germination of Chloris truncata after 21 d of incubation.
Fig 2.
Effect of sodium chloride (NaCl) concentration on seed germination of Chloris truncata after 21 d of incubation at 25/15°C day/night temperature.
The line represents a three-parameter sigmoid model fitted to the data. The arrow shows the NaCl concentration required to inhibit 50% germination. Vertical bars represent standard error of mean.
Fig 3.
Effect of osmotic potential on seed germination of Chloris truncata after 21 d of incubation at 25/15°C day/night temperature.
The line represents a three-parameter sigmoid model fitted to the data. The arrow shows the osmotic potential required to inhibit 50% germination. Vertical bars represent standard error of mean.
Fig 4.
Effect of pH on seed germination of Chloris truncata after 21 d of incubation at 25/15°C day/night temperature.
The line represents a quadratic model fitted to the data. Vertical bars represent standard error of mean.
Fig 5.
Effect of seed burial depth 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 seed burial depth required to inhibit 50% emergence. Vertical bars represent standard error of mean.
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.
