Claim · model-written summary
Heavier seed weight partly, and sometimes fully, compensated for the potential yield decrease caused by shading-reduced seed number.
Sorghum bicolorVerbatim
e0“‘Georgia 615’ grain sorghum ( Sorghum bicolor (L.) Moench) was shaded for weekly periods in three field experiments”
e5“When number of seed per panicle was reduced by shading, heavier seed weight compensated for part, and sometimes all, of the potential yield decrease”

Other claims from this paper (4)
- Intervention effect Shading in the stage from the pre-boot vegetative stage to full panicle expansion reduced seed number per panicle.
- Intervention effect Shading in the milk and dough stages after 50% anthesis resulted in lighter seed.
- Intervention effect Shading in the milk and dough stages had little or no effect on seed number per panicle.
- Intervention effect Grain yield per panicle and per hectare of shaded sorghum was generally lower than in the unshaded check.
