Can perennial C4 grasses attain high efficiencies of radiant energy conversion in cool climates?

This study provides the evidence that the superior potential light conversion efficiencies associated with C4 photosynthesis can be realized under cool temperate conditions and that such climatic conditions do not Inherently impair the C4 process

Scholarcy highlights

  • C4 plants are considered to have higher conversion efficiency and productivity than C3, plants, this advantage may not be realized under sub‐optimal conditions
  • The conversion efficiencies of these species were examined for 2 years in fertilized, irrigated, replicated plots in south‐eastern England
  • The M. × giganteus crop attained shoot productivity of 2.87 kg m−2 between April and September, exceeding the highest values typically obtained with intensively managed C3, crops
  • This study provides the evidence that the superior potential light conversion efficiencies associated with C4 photosynthesis can be realized under cool temperate conditions and that such climatic conditions do not Inherently impair the C4 process
