Claim · model-written summary
Late planting restricted vegetative growth and reduced photosynthesis, grain carbohydrate accumulation and final yield in the late maturing variety.
ZeaVerbatim
e0“In late planting, however shorter day length restricts vegetative growth and lower temperature during ripening period degresses photosynthesis and accumulation of cabohydrate in grains, and these bring decrease in yield finally.”

Other claims from this paper (14)
- Intervention effect Somewhat late planting gave the early maturing variety more grain yield than other planting times.
- Intervention effect Earlier planting gave the late maturing variety more grain yield than late planting.
- Intervention effect Earlier planting gave early maturing plants less dry matter weight than somewhat late planting throughout growth.
- Intervention effect Early planting increased dry matter accumulation of the late maturing variety in early growth relative to later planting.
- Intervention effect Before silking, early and later planted plants had similar increases in dry matter weight.
- Intervention effect After silking, early planted plants gained dry matter weight faster than later planted plants.
- Observation Nitrogen and carbohydrate content followed a pattern similar to dry matter weight across growth.
- Observation The early maturing variety was insensitive to day length.
- Observation The early maturing variety differentiated tassel primordia under long days after basic vegetative growth.
- Intervention effect Early planting yielded less carbohydrate accumulation in grains.
- Intervention effect Late planting reduced growth and yield of the early maturing variety.
- Observation The late maturing variety was sensitive to day length.
- Observation In the late maturing variety, tassel primordia did not differentiate until day length shortened.
- Intervention effect Earlier sowing gave better grain yield.
