Several aspects of genotype-environment interaction may act to modulate natural selection in populations that encounter variable environments. In this study the norms of reaction (phenotypic responses) of 20 cloned genotypes from two natural populations of the annual plant Polygonum persicaria were determined over a broad range of controlled light environments (8%-100% full sun). These data reveal both the extent of functionally adaptive phenotypic plasticity expressed by individual genotypes, and the patterns of diversity among genotypes for characters relevant to fitness, in response to an environmental factor that is both highly variable within populations and critical to growth and reproduction.
基因型与环境的相互作用的几个方面可能会在遇到多变环境的种群中调节自然选择。在本研究中，测定了来自一年生植物春蓼两个自然种群的20个克隆基因型在广泛的可控光照环境（全日照的8%-100%）下的反应规范（表型反应）。这些数据揭示了个体基因型所表现出的功能适应性表型可塑性的程度，以及基因型之间与适合度相关性状的多样性模式，以应对种群内高度可变且对生长和繁殖至关重要的环境因素。
