Average fresh weight of soybean somatic embryos (SSE) tissues cultured in different 1/5 (FNL) culture media without asparagine containing: Lysine plus Threonine, two ALS inhibitor herbicides (Exceed and Synchrony) and a lysine analog (AEC). The medium containing Lysine plus threonine (x) was found to be less effective than the other compounds (with about 70% growth inhibition obtained after 120 days). The Exceed containing medium (◆) was found to be more efficacious than the one containing Synchrony (●). However, in either case it took four weeks for all SSE tissues growth to be completely inhibited. With the medium containing the lysine analog AEC (▲), 100% of the SSE tissues ceased growth after a period of four months at all treatment levels. n = 3
