Flowering in the tillers from which leaf samples were collected
Control tagged plants at 1070 m did not flower in 2017 and 2018, but did
in 2019, a masting year (Table 1). Since activation of floral
development initiates a year before anthesis (Appendix S1), leaf samples
from these control plants (18Control; January 2018) were included in the
study. Some tillers collected from the plants that had been moved to
other altitudes (16Hot, 16Cool, and 17Hot) flowered in the next season
(Table 1). Flowering was recorded for each of the tagged tillers and all
the leaf samples were then correspondingly identified as being from
tillers that subsequently flowered or not (Table 1).
