Phenology
The number of days to first flowering significantly varied with
germination strategy and was not affected by soil warming (Fig. 1, Fig.
4, Table 1). Although warming did not affect flowering time, it
accelerated time to seed maturity and reduced the overall duration of
seed production. Immediate germination strategy plants flowered 50 days
earlier and the seeds were relatively slower to mature compared to the
three other strategies (Fig. 4, Table 1). Consistent with their early
flowering date, absolute timing of seed maturity of immediate strategy
was earlier compared to the other strategies (Fig 4, Table 1). Finally,
the plants senesced earlier in warmer soil than in ambient soil (Fig. 1,
Fig. 4, Table 1). At the end of the experiment a greater proportion of
plants survived in the ambient than warmed conditions for all
germination strategies except the postponed strategy, in which mortality
was approximately 95% regardless of growth temperature (Fig 4, Table
1).
