The study looked at how super-high-yield wheat farming methods can improve photosynthesis and yield. Researchers studied the changes in photosynthesis and environmental factors in wheat plants during the grain-filling stage. They found that super-high-yield cultivation led to higher CO2 assimilation rates and better photosystem II electron transport compared to high-yield cultivation. The environmental conditions like leaf and soil temperature also favored higher photosynthesis rates in super-high-yield wheat fields. The study suggests that these factors contribute to the higher biomass and yield in super-high-yield wheat cultivation.
