      abstract     = {Spring ephemerals of deciduous forests appear shortly after
                      snow melt and senesce shortly after the overstorey canopy
                      has closed. During this short period, they take advantage of
                      the high light conditions, but also of the low-temperature
                      regime that favours growth in these species. This better
                      growth at cooler temperatures has been attributed to longer
                      leaf life duration. The objective of this study was to test
                      if temperature effect on growth in spring ephemerals can be
                      explained solely by the leaf life duration, or if there is
                      also a direct temperature effect on the underground organ
                      growth. Crocus vernus (L.) Hill was exposed to two
                      temperature regimes, 12/8 and 18/14°C (day/night), for
                      sequential harvests and to four differential air to soil
                      temperature regimes: 12/12, 12/18, 18/12 and 18/18°C
                      (air/soil temperature). Dry mass, leaf nitrogen, starch
                      concentration and cell size of the new corm were determined.
                      Final dry mass and cell size were higher at the lower
                      temperature regime while leaf lasted longer than at the
                      higher temperature regime. Although both air and soil
                      temperatures had an impact on the different growth
                      parameters measured, the impact of soil temperatures was
                      greater and it also influenced leaf life duration. At higher
                      temperature, corm growth stopped before the first visual
                      sign of leaf senescence, suggesting that corm growth
                      controls leaf life duration in C. vernus rather than the
                      opposite and that crocus growth becomes rapidly sink limited
                      at higher temperatures.},
