| Parameters | Equations |
|---|---|
| Germination potential (GP) | The number of normally germinated seeds on the 6th day/the total number of tested seeds ×100 |
| Germination rate (GR) | The number of normally germinated seeds/the total number of tested seeds ×100 |
| Germination index (GI) |
 , where Ni is the number of seeds that emerged on the ith day, and Ti is the day counted38. |
| Germination rate index (GRI) |
G1/1 + G2/2+… + Gx/x, where, G1 = germination rate at first day after sowing; G2 = germination percentage at second day after sowing; Gx = germination percentage at x day after sowing39. |
| Seedling vigour index (SVI) | Seedling length × Germination percentage/10040. |
