Shining a Light on Patterns of Photoperiod Sensitivity in Germination and Flowering Across Latitudes, Ecosystems and Functional Traits.

ABSTRACT: In photoperiod sensitive plants, the timing of phenological events depends primarily on day length rather than temperature, precipitation or other environmental variables. This may make these photoperiod sensitive species less able to respond to climate change as their phenologies are more tightly controlled by day length conditions, which remain constant into the future, than by changing climatic conditions. We measured germination under three light treatments (short-day, long-day and equal light and dark) to quantify species' germination photoperiod sensitivity. We developed a novel metric that provides a continuous measure of germination photoperiod sensitivity for 67 plant species across a range of locations, habitats and growth forms. Of the 67 species, four species had significantly
