Alterações nos caracteres de plantas M₁ de Phaseolus vulgaris derivadas de sementes tratadas com etil-metanossulfonato
Palavras-chave:
etil-metanossulfonato ems, mutações induzidas, germinação de sementes, produção de grãos, cor do tegumentoResumo
Seeds of Phaseolus vulgaris cv. Milionário 1732 were treated with ethyl methanesulfonate (EMS) solutions with the following concentrations: 0 (control), 0.0625, 0.125, 0.25, and 0.5% (v/v). Increased concentrations of EMS reduced percentage of germination, survival, plant height, number of seeds per pod and yield. The number of pods per plant was not reduced, but pod size decreased.
