Table II. Water content at harvest and germination indexes of Brassica napus seeds produced by plants grown under control, LS70, LS53, and LS32 conditions.
| Water content (%) | Final germination rate (%)a | T′5 (h)b | T′10 (h)b | T′50 (h)b | CRGc | |
|---|---|---|---|---|---|---|
| Control | 6 ± 0.1 | 93.3 ± 2.8 | 21.2 ± 0.3 | 22.6 ± 0.2 | 29.4 ± 1.0 | 2.37 ± 0.01 |
| LS70 | 5.9 ± 0.1 | 92.3 ± 2.3 | 23.2 ± 0.3 | 24.2 ± 0.3 | 28.9 ± 0.9 | 2.37 ± 0.02 |
| LS53 | 6 ± 0.2 | 91.5 ± 2.1 | 23.1 ± 0.3 | 24.5 ± 0.3 | 30.8 ± 1.0 | 2.32 ± 0.01 |
| LS32 | 7.5 ± 0.1 | 40.3 ± 3.5 | 24.1 ± 0.3 | 26.3 ± 0.3 | 36.5 ± 1.2 | 2.22 ± 0.02 |
The values are shown as mean ± S.E. (n = 4). Significant differences from the control value are indicated in bold (p < 0.05).
a Determined at 58 h.
b Time required in order to achieve 5% (T′5), 10% (T′10), or 50% (T′50) germination, calculated from the Gompertz equation (28).
c Coefficient of the rate of germination, as calculated by Bewley and Black (11).
