Fig. 6.

Onset and completion of four stages of flowering [flag leaf exertion, panicle exertion, anthesis, and maturity (seed set)] in an individual stem of each of six Miscanthus sacchariflorus lines from different latitudes ±SE (n=7). Data are shown in response to warm and cool temperature regimes from Experiment 2 that differed in accumulated temperature by 180 °Cd. An asterisk indicates that flag leaf exertion was the furthest developmental stage reached. (A) Photoperiod at each flowering stage. (B) Degree days at each flowering stage.
