Other claims from this paper (16)
- Observation Maximum kernel dry weight occurred 43 to 47 days after silking except in very late plantings.
- Observation Very late mid-June plantings reached maximum kernel dry weight at 48 and 66 days after silking.
- Observation Kernel moisture declined linearly.
- Observation Untreated seed harvested 72 to 75 days after silking from mid-April plantings gave an 80% stand the next year.
- Intervention effect Harvest at maximum dry weight produced final stands of 20% or lower.
- Intervention effect Delaying planting until mid-May reduced maximum field emergence to 50% in 1987.
- Intervention effect The mid-May planting delay did not reduce maximum field emergence in 1988.
- Intervention effect Mid-June planting lowered maximum emergence to 30% in 1987.
- Intervention effect Mid-June planting lowered maximum emergence to 40% in 1988.
- Observation Laboratory germination maxima preceded field emergence maxima by 12 to 26 days.
- Observation Black layer formation preceded immaturity-related low vigor.
- Association Soil cold test correlation with final stand had median r = 0.87, exceeding rolled-towel germination.
- Association Accelerated aging correlation with final stand had median r = 0.85, exceeding rolled-towel germination.
- Association Mean leachate conductance correlation with final stand had median r = −0.88, stronger than rolled-towel germination.
- Intervention effect Early harvest at 45 to 60 days after silking produced high germination but low vigor.
- Intervention effect Leaving crops until 80 to 90 days after silking consistently produced relatively high-vigor seed unless planted very late.
