Summary Effects of population with different origin, biotype, seed size, temperature and depth of burial on the emergence of germinated seeds were investigated to assess the possibilities for successful management of triazine resistant populations of Solanum nigrum. Emergence fraction increased with temperature and decreased with increasing depth of placement. Emergence fraction appeared to be highest at intermediate seed weights. Resistant seeds showed a higher emergence fraction than susceptible seeds while emergence rate of resistant seeds was slightly lower. Emergence rate increased with increasing temperatures and decreasing depths. The possibilities for management of resistant S. nigrum with a stale seedbed preparation are discussed.
