Figure 1. Total seed number is a function of the amount of photosynthate production from R1 to R5 that is allocated to reproductive growth divided by the minimum amount of photosynthate required by a seed.
Figure 2. Final seed weight is a function of the rate of seed growth and the duration of the seed fill period.
Figure 3. The main factors affecting final yield in soybean are the amount of photosynthate produced from R1 to R5 and the length of the seed fill duration.
