DIVERSITE GENETIQUE ET PHENOLOGIE DE CYPERUS ESCULENTUS L. (CYPERACEAE) POUR UNE GESTION INTEGREE DE L'ESPECE DANS LES CULTURES DE HAUTE LANDE
2006
We studied the development, phenology, demography and genetic diversity of Cyperus esculentus (Cyperaceae), an invasive clonal perennial weed in the small-statured crops of Haute Lande, southwestern France. The goal was to understand its colonizing capacity and then make propositions for an integrated management of the species.The colonizing capacity of C. esculentus is linked to the huge subterranean vegetative development, with both foraging thanks to rhizomes and multiplication thanks to tubers. On the other hand, the local crop systems provide all the needs of the species: water, light and nutriments without competition by other weeds. Genetic analyses showed a low genetic diversity and…
