Establishing background sensitivities of a range of species from different sites range of herbicide treatments.

摘要

Seed from field populations of a range of species were collected and tested for background sensitivity to herbicides. Results are illustrated using Papaver rhoeas and Stellaria media. Plants raised from these populations were sprayed with five-seven doses of metsulfuron-methy 1. One population of S. media showed much greater tolerance than did the other populations. Aspects of seed collection, sampling and interpretation of the results are discussed.
