The key message of this section is that plant development will not necessarily
track a given trend in temperature. Annual plants may rapidly evolve new photoperiodism
genotypes (Heide, 2001), and in the case of trees, this is not a reasonable scenario. In case of rapid climatic warming, the given diversity of genotypic phenology
responses will affect intraspecific competition and may change species composition,
at least in long-lived plant taxa that have no time to evolve new genotypes
