In some cases, quick and relatively uniform germination is desirable even in the coldest treatment, to reduce noise among populations. In our case, a minimum plant size was also needed for the plants in the coldest treatment to allow for the harvest of fresh green material, at the beginning of the second season, for DNA extraction without impacting growth or phenology. This required starting out with a uniform \u2018greenhouse\u2019 regime, which gradually diverged and morphed into climates of 2, 6 and 10 \u00b0C MAT. The second season started with the \u2018real\u2019 target climates of MAT 1, 6 and 11\u00b0C.<\/p>\n

\"Modification<\/a>
Modification of germination temperatures to speed up germination, achieve necessary plant sizes and reduce noise. On the left: the first 14 weeks gradually evolve from a \u2018greenhouse\u2019 regime to a real MAT 6\u00b0C regime. Right: the last ten weeks are unmodified.<\/figcaption><\/figure>\n
