Grain yield in wheat: Effects of radiation during spike growth period

The effect of radiation on yield formation in irrigated and fertilized spring wheat was quantified, focusing on the crop growth and partitioning during the spike growth period, critical for the determination of number of grains. Most of the data were obtained from five experiments at Balcarce, Argentina, with cv. PROINTA Oasis. Additional data were obtained from an experiment in Sonora, Mexico. A wide range of incident radiation during spike...
