Estudio de los mecanismos de resistencia a glifosato en dos biotipos de lolium spp.

The aim of this study was to analyse the glyphosate resistance mechanisms in Lolium multiflorum and Lolium rigidum. Both these species were collected in Spain, the former in Andalusia in olive grove crops and the latter in citrus plantations in Valencia. These were compared to a susceptible population of both species, which had never been treated with herbicides. Absorption-translocation, contact angle and retention assays were performed. The experiment design used was completely random with six replications. The study was performed as a consequence of data previously obtained for screening and dose-response trials, and which served to confirm the resistance of the resistant biotypes. Regar…
