Other claims from this paper (16)
- Observation Spring wheat emerged 7 to 15 days after planting.
- Observation Growing degree days to emergence ranged from 94 to 138 and averaged 106.
- Observation Time to emergence did not differ among cultivars within trials.
- Observation Eighteen of the cultivars produced eight leaves.
- Observation ‘James’ produced seven.
- Observation HRS cvs. Butte and Waldron had a main-stem phyllochron interval of 73 GDD.
- Observation “other” eight‐leaved HRS cultivars had a main-stem phyllochron interval of 81 GDD.
- Observation durums had a main-stem phyllochron interval of 81 GDD.
- Observation James had a main-stem phyllochron interval of 81 GDD.
- Method / resource Combined analyses had an R-squared value at least 0.970, significant at 0.01.
- Intervention effect fertilizer N rate had no effect on main stem development rate.
- Intervention effect Soil water level affected maximum tiller number per plant.
- Intervention effect fertilizer N rate affected maximum tiller number per plant.
- Observation Growing degree days per growth unit were equal across the two developmental periods.
- Method / resource GDD and PTU estimated growth rates and stages with equal precision.
- Method / resource GDD and PTU estimates were more precise than DAYS.
