文摘
- •
Sowing date effects on maize were studied under near-optimal growth conditions.
- •
Field experiments covered a wide range of contrasting photo-thermal conditions.
- •
An original method was proposed to assess source-sink relationships.
- •
The variation of source capacity across sowing dates was higher than that of sink strength.
- •
Source/sink ratio decreased from early to late sowing dates.
