Changes in the percentage photosynthetic active radiation (PAR%) with canopy depth as indicated by the cumulative leaf area index (LAI) at the start of spike emergence (Z50-52) and late anthesis (Z69-70) in two pairs of near- isogenic lines differing in the tin gene (7770/7770tin and B/Btin) at Canberra, 2013. The data pair PAR% = 100 and LAI = 0 corresponds to the measurements taken above the canopy, and the lowest PAR% and greatest LAIs were measured at ground-level. Bi-directional error bars show ± one standard error.
