S ummary Changes in nitrate reductase activity in response to nitrogen treatment were measured in vivo in the basipetal part of the youngest ligule emergent leaf of wheat plants during early development. The relationship between these measurements and grain yield is reported for some spring wheats grown in a growth room and some field‐grown winter wheats. In both situations the c correlation of a linear regression of yield parameters and single measurements of nitrate reductase was found to be significant. Where split dressings of nitrogen were applied the seasonal mean nitrate reductase activity correlated well with yield.
