Fig. 3

Thermal time of B. pilosa seeds from three populations predicted by thermal time models based on Normal distribution at different water potentials at suboptimal temperatures. The red circles show the observed mean thermal times and the black dashed lines show the predicted thermal times fitted by the thermal time model
