Flowering in the tillers with leaf samples collected
Control tagged plants at 1070 m did not flower in 2017 and 2018, but did
in 2019, a masting year. 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 i.e. in
2017, 2017 and 2018, respectively. 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).
