Germination percentage and fertility in wild type and homozygous GA biosynthesis or response mutants
| Plant | Germinationa (%) | Seeds/siliqueb |
|---|---|---|
| Ler | 99.7 | 42.1 ± 1.2 |
| rga-24 | 99.3 | 40.4 ± 2.2 |
| gai-t6 | 100.0 | 39.9 ± 1.6 |
| rga-24/gai-t6 | 99.6 | 7.6 ± 1.0 |
| ga1-3 | 3.5 ± 1.3 | Sterile |
| rga-24/ga1-3 | 5.3 ± 2.4 | Sterile |
| gai-t6/ga1-3 | 2.1 ± 0.9 | Sterile |
| rga-24/gai-t6/ga1-3 | 3.1 ± 1.5 | Sterile |
Values are means ±SE.
↵a A total of 220–310 seeds per line were tested. ga1-3 background seeds were tested three times, except for rga-24/ga1-3, which was tested twice.
↵b Fertility was measured by the number of seeds per silique on the primary inflorescence stem for 10 plants/line. For Ler, rga-24, and gai-t6, seed number in 14 siliques per plant was counted. Because the first 4 siliques of rga-24/gai-t6 were completely sterile, the mean was determined for siliques 5 to 36.
