Ppd-H1 affects the duration of leaf elongation, cell number, cell size, and LL under LD conditions. A, LERs were determined by measuring the LL every 3 d under LDs in Scarlett (solid line, triangle) and S42-IL107 (dashed line, square) in the fifth leaf of the main shoot. Breakpoints of the regression model and their 95% confidence intervals are indicated for the different genotypes and conditions above the regression curves. B to D, Cell length (B), estimated number of interstomatal cells (C), and final LL (D) of the fifth fully expanded leaf on the main shoot. Barley genotypes with the mutated ppd-H1 allele and ILs with the photoperiod-responsive Ppd-H1 allele are represented by gray and white bars, respectively. Bars represent means with 95% confidence intervals (n = 5).
