translate English to French: We also cultivated plants from wetland and pasture populations and estimated genetic variance for several morphological traits. We did not find any significant differentiation to suggest differential selection between populations from the two habitats.
Nous avons ensuite cultivé en serre des plants de phalaris issus de pâturages et de zones humides afin d'évaluer la variance génétique pour des traits quantitatifs dans les deux habitats.
