Fig. 6. The number of myonuclei in single muscle fibre segments of 1 cm length in
relation to muscle fibre diameter for the 4 June sample (see
Table 1) for the ambient
(closed circles) and photoperiod-manipulated treatment (open circles).
First-order linear regressions were fitted to the data with the following
equations. For the ambient photoperiod: myonuclei number=288.6+14.4(fibre
diameter) (r2=0.80; ANOVA:
F1,159=627.2, P<0.001). For the manipulated
photoperiod: myonuclei number=1258.1+12.4(fibre diameter)
(r2=0.34; ANOVA: F1,230=118.4,
P<0.001).
