                      ecotypes from Sweden and Italy) versus summer (Helianthus

                      Romanesco) annuals. Significant relationships existed among
                      leaf dry mass per area, photosynthesis, leaf thickness and
                      palisade mesophyll thickness. While the acclimatory response
                      of the summer annuals to cool temperature and/or high light
                      levels was limited, the winter annuals increased the number
                      of palisade cell layers, ranging from two layers under
                      moderate light and warm temperature to between four and five
                      layers under cool temperature and high light. A significant
                      relationship was also found between palisade tissue
                      thickness and either cross-sectional area or number of
                      phloem cells (each normalized by vein density) in minor
                      veins among all four species and growth regimes. The two
                      winter annuals, but not the summer annuals, thus exhibited
                      acclimatory adjustments of minor vein phloem to cool
                      temperature and/or high light, with more numerous and larger
                      phloem cells and a higher maximal photosynthesis rate. The
                      upregulation of photosynthesis in winter annuals in response
                      to low growth temperature may thus depend on not only (1) a
                      greater volume of photosynthesizing palisade tissue but also
                      (2) leaf veins containing additional phloem cells and
                      presumably capable of exporting a greater volume of sugars
                      from the leaves to the rest of the plant.},
