Number of kernels in wheat crops and the influence of solar radiation and temperature

SUMMARY The number of kernels per m 2 ( K ) in well managed and watered wheat crops was studied using results of experiments in Mexico and Australia in which short spring wheat cultivars were subjected to independent variation in radiation, largely via artificial shading, and in temperature. Also crops subjected to differences in weather (year), sowing date and location within Mexico, revealed responses to the natural and simultaneous variation...
