Could wheat be made a little more like maize?

摘要

Wheat yields could potentially double as scientists seek to make the crop's efficiency of photosynthesis similar to that of maize plants. Maize draws in more carbon dioxide than wheat does, making it twice as efficient at transforming light energy into biomass and hence yield. Scientists at Rothamsted Research see improving the photosynthesis of wheat as key after setting out a programme to raise top yields by a third.
