Vegetative and flowering traits of B73 in the field pot study, Johnston, IA
| Treatment | Plant height (cm) | Plant growth rate (cm/day) | Leaf no. | Leaf appearance rate (leaves/day) | GDDC to shed | GDDC to silk | ASI |
|---|---|---|---|---|---|---|---|
| WW | 223.9 ± 12.8 | 5.41 | 20.4 ± 0.8 | 0.34 | 715.9 ± 14.5 | 730.5 ± 14.0 | 1.6 ± 1.1 |
| DRT | 178.4 ± 9.9a | 3.57 | 20.0 ± 0.9 | 0.29 | 750.5 ± 13.5a | 798.4 ± 11.0a | 4.8 ± 1.9a |
Vegetative traits were collected weekly. Final measurements were collected at R2 stage. Growth rate and leaf appearance rate were calculated using linear regression based on data in Figure 2. Measurements represent mean ± SD. One day is approx. 11 GDDC, growing degree days.

DRT means are statistically different from WW at p < 0.01.
