Sustained assimilate supply determines grain development in wheat under post-anthesis heat.

Abstract excerpt

Short episodes of post-anthesis heat restrict grain filling by accelerating leaf senescence, reducing photosynthetic capacity, and limiting assimilate supply to developing grains. We explored the contribution of assimilates, derived from both current photosynthesis and remobilisation, for sustaining wheat yield under post-anthesis heat. Two recombinant inbred lines, SB062 and SB003, were subjected to 7-day heat...
